In the plants of food and beverage manufacturers, there are times when monitoring and recording of production equipment is necessary inside clean rooms. This is an introduction to monitoring and recording in clean rooms using paperless recorders.
Operators must receive diagnostic information before a line block leads to a malfunction. Yokogawa provides predictive diagnostics based on trend analysis of the blocking factor, which improves maintenance efficiency and reduces maintenance costs.
Steam is still one of the most popular methods of providing an energy source to a process and its associated operations. The more accurate and reliable measurements that are made, the more informed decisions can be taken that affect costs and product quality.
In order to reduce emissions of air pollutants such as sulfur oxides (SOx) and nitrogen oxides (NOx), power plants have installed flue gas desulfurization systems known as scrubbers.
In flue gas desulfurization systems that use magnesium hydroxide (Mg(OH)2) slurry, the consumption of the desulfurization agent (Mg(OH)2) is controlled by using online pH analyzers. A great concern in the pH measurement is heavy staining of the pH electrodes by the Mg(OH)2 slurry. To ensure accurate measurement, frequent cleaning of the electrodes with an acid is required, adding to both maintenance workload and cost.
Control of sodium chloride (NaCl) concentration at a salt dissolver where solid salt is dissolved in water, is highly important because of the electrolysis efficiency. A conventional way of measuring the concentration of supersaturated NaCl solution had been performed by using non-contact type sensors (e.g., γ-ray density meter) since NaCl, impurities, and precipitates are in the solution.
There are various methods for continuous fabric dyeing as well as dye fixing. When dye is directly applied, steaming (heat treatment) is required. At present the pad-steam method is widely used for continuous dyeing. To ensure stable product quality, the humidity in the steamer is kept at a constant level.
Caustic soda is an important basic material in the chemical industry and is mainly produced by the electrolysis of soda. In the electrolysis process to make concentrated caustic soda, the DM8 Liquid Density Meter ensures high product quality through accurate measurement of liquid density.
Process liquid analyzers such as pH meters, conductivity meters, ORP meters, and density meters play an important role at electrolysis plants in the control of concentrations of various process solutions. This requires both precision and stability under harsh conditions that include highly corrosive substances, high temperatures, and many impurities.
Many different types of gases are consumed in industries as varied as chemicals, food & beverages, and medical. These gases are normally delivered in liquid form by trucks and dispensed at the customer site. Although the flow volume of cryogenic liquefied gas is used for billing purposes, it is not easy to accurately measure this because the gas is always at saturation temperatures.
The discharge of improperly treated industrial chemicals and fuel gas can have a major impact on the environment, posing a serious threat to public health. Concurrent with the global growth of manufacturing operations to keep pace with market trends, many countries are taking measures to deal with environmental problems.
For safe and efficient operation, the quality of feedwater, steam, and condensate in boiler plants must be controlled and maintained in the most favorable conditions.
With industrial and economic development comes increasingly large and advanced power plants and factories. Nevertheless, we find many cases where the original cables, cable tunnels, and other components of the power infrastructure have languished under continuous operation.
Fired heaters are used for various processes in oil refining and petrochemical plants.
Both bulk and finished inventories are stored in distributed tank farm remote from the site operations. These are difficult to instrument due to the infrastructure cost involved. These are then monitored daily by patrol rounds. While effective, this method does require a large skilled labor force to monitor all of tanks. This can impose an additional risk when the stored medium is of a hazardous nature.

In maintaining and managing industrial plants, monitoring waste water pH/ORP is both a legal obligation and an unavoidable necessity for protecting the environment. Monitoring without an attentive eye can lead to severe consequences.
Pressure measurement of tubeless tyres to monitor the air loss is one of the key performance tests in the tyre manufacturing units. Relocation of tyres from one testing rack to the other for various tests and frequent movement of the testing setup for conditional tests to various locations calls for cable free implementation for ease of handling.
To defray energy costs, many industrial plants have their own boilers to generate steam to produce a portion of their energy needs. In addition to generating power, the steam may also be used directly in plant processes or indirectly via heat exchangers or steam jacketed vessels.
Heat exchangers are devices that provide the flow of thermal energy between two or more fluids at different temperatures. Heat exchangers are used in a wide variety of applications. These include power production; process, chemical and food industries; electronics; environmental engineering; waste heat recovery; manufacturing industry; and air-conditioning, refrigeration, and space applications.
Ion Exchange is a method for the exchange of ions between two electrolytes or between an electrolyte solution and a complex molecule. In most cases the term is used to denote the processes of purification, separation, and decontamination of aqueous and other ion-containing solutions with solid polymeric or mineralic ion exchangers.

Visual MESA© is a steam system optimization and management computer program that was originally developed at Chevron and now marketed by Nelson & Roseme, Inc. Visual MESA is currently used at refinery and chemical manufacturing sites to optimize the overall site steam system and the parts of the electrical system that economically trade off with the steam system.
This paper will explore significant optimization variables and constraints commonly encountered in refinery steam system optimization, the strategies Visual MESA uses to deal with them.
In the course of more than twenty years as an engineer involved directly in utility related projects in a number of industries, I have seen a great variety of energy efficiency projects and programs covering the entire spectrum of efficacy. The Deer Park, Texas, plant of the Rohm and Haas Company has a unique energy management program that has proven to be highly successful. This program has resulted in a 17 percent reduction in energy use on a per pound of product basis, saving 3.25 trillion btus and $15 million each year! This article discusses this program, its history, successes, and the unique characteristics that have contributed to those successes.
In general, refineries exhibit a very good potential for real time monitoring and optimization using Visual MESA Energy Management System.
Based on our extensive experience, overall benefit in the range of 2% to 5% of the total energy cost can be achieved. Expected project payback is always less than one year.
The REPSOL company had in mind the improvement of the control on one of their chemical reactors. A feasibility study for the implementation of an Advanced Control technique (Predictive Control for temperature control for chemical Reactors - PCR) for a batch reactor for Polyols production has been performed. The proposed technique PCR is based on a dynamic model of the unit which makes the prediction of the process variables behaviour.
This paper will not describe just all the features of the software or fully explain on-line optimization technology. The objective of this work is to present some interesting facts and lessons from the experience of implementing a cost based optimization program at thirty oil refineries and petrochemical complexes, around the world, since 1997. This paper will focus on the key optimization variables and constraints in steam system optimization, how they should be handled and how the human and organizational aspects can be addressed.
Industrial facilities where power and steam is produced (i.e., Cogeneration) exhibit a very good potential for real time monitoring and optimization using Visual MESA Energy Management System.
Based on our extensive experience, overall benefit in the range of 2% to 5% of the total energy cost can be achieved. Expected project payback is always less than one year.
Visual MESA was successfully applied to many industrial facilities worldwide, several of them operating steam and power generation networks of different complexity and capacity but all with energy cost savings.
This paper discusses real industrial examples in which the sitewide utilities system of refinery and petrochemical Sites are optimized with a real time, on line, industrially proven software. Experiences gained during more than 20 years of industrial projects deployed worldwide are commented (Refs. 1 to 10 are related to some recent projects). Main project steps are explained and critical details to be taken into account to assure successful use and proper technology transfer are presented. Specific case studies will be discussed in the paper.
Utilities and energy systems are often the major source of SOx, NOx and CO2 emissions, therefore, emissions control and the management of credits and quotas are tightly interrelated with energy management.
In the case of refineries, chemical and petrochemical plants, energy represents the main cost (second to feedstock) and therefore its reduction has become a bottom line business decision. The energy systems at these sites are inherently complex, with the emissions cost analysis and limits compliance introducing an additional factor to the complexity of the energy costs reduction challenge.
Process plants use different type of fuels, they often operate cogeneration units, their steam networks consist of several pressure levels, there are different types of energy consumers and there are emission limits to be observed. Import or export of electricity in deregulated markets, which could also be traded off with more or less CO2 and other contaminant gaseous emissions, increase the optimization problem complexity.
After a feasibility study, Repsol YPF decided to apply a model-based predictive controller to a batch reactor producing polyols. The predictive controller for reactors (PCR) is a set of control modules that are designed to face most of the reactor configurations. The important increase of production is a consequence of the better handling of the reactor temperature. Here's a description of the unit and control objectives, methodology, project steps, results and the corresponding benefits.
Big and complex industrial facilities like Refineries and Petrochemicals are becoming increasingly aware that power systems need to be optimally managed because any energy reduction that Operations accomplish in the producing Units could eventually be wasted if the overall power system cost is not properly managed. However, process engineers always attempted to develop some kind of tools, many times spreadsheet based, to improve the way utilities systems were operated. The main drawback of the earlier attempts was the lack of data: engineers spent the whole day at phone or visiting the control rooms to gather information from the Distributed Control System (DCS) data historian, process it at the spreadsheet and produce recommendations that, when ready to be applied, were outdated and not any more applicable.
This paper addresses some of the root causes for issues and discusses the best practices that will help to avoid project failures. Main project steps are explained and critical details to be taken into account to assure successful use and proper technology transfer are discussed. It also presents real industrial examples in which the whole utilities system cost of a production Site (i.e., steam, fuels, boiler feed water and electricity) is optimized with a real time, online, industrially well established software.

The energy systems, the steps for the implementation of Visual MESA and several features of the model are described in this article, with a focus on the use of the software for the calculation of energy-related KPIs. The EMS implementation project is discussed and the main conclusions relative to the reduction in operating costs are also presented.
Experiences gained during more than 20 years of industrial projects deployed worldwide are commented.

Alarm management is not just a project that has a start and end date; it's a continuous cycle. Once the alarm system has been reviewed and improvements have been identified, we must check that controls are in place to ensure the alarm system remains functional. The key is to ensure that the system is continuously monitored and any changes are fully documented. There are seven key steps for alarm management. Rationalization is one of those critical steps.
This paper shows how to improve distillation operations by focusing on procedure automation. It will review the importance of using procedures in distillation operations and highlights the collaboration work underway between Fractionation Research Inc. (FRI) and Yokogawa Corporation to improve procedural operations.
The worlds of process automation and production management have been converging for some time. What once used to be islands of automation and production management functionality connected through highly proprietary integration schemes that were costly to maintain have developed into integrated platforms that provide seamless data exchange between the world of automation and the plant floor, the functions of production and operations management, and integration with business level systems.
The world of process automation is governed by procedures. While we like to refer to the process industries as being largely "continuous", this could not be further from the truth. Process manufacturing is constantly in flux.
From engineering to installation, commissioning, operations, and maintenance, FOUNDATION fieldbus offer significant cost reductions of 30 percent or more versus conventional analog systems. Many of these cost reductions come from the advanced functions that fieldbus offers versus analog technology.
The automation suppliers that will be successful in the long term will be those that effectively address application or industry specific problems for end users with a value proposition that cannot be ignored. These problems exist throughout the process industries today, and they won't be solved by simply offering a product, but through a combination of hardware, software, services, application expertise, and knowledge.
In ARC's view, customers need a compelling business value proposition to justify investment in any kind of automation. Vigilance and VigilantPlant were created with this in mind. Yokogawa's vision with VigilantPlant is to create an environment where plant personnel and operators are well informed, alert, and ready to take action.
Yokogawa has come a long way in making its message clear to the world of process automation. Last year, the company embarked on a full-scale global marketing campaign to make customers aware of the company's focus on system reliability, security, dependability, and robustness. Dubbed "Vigilance", the campaign created a unified message for the company and greatly helped expand awareness of the Yokogawa brand and corporate philosophy.
Process automation end users are under more pressure than ever to do more with less. The current economic climate means that many automation capital projects are on hold. With capital budgets tighter than ever, users instead focus on operational budgets (where cost cutting is also a key concern), or on automation investments with a very rapid return on investment.
In today's dynamic industrial marketplace, the only constant is change. Raw material costs, energy costs, market demands, environmental and safety regulations, technology, and even the nature of the labor force itself are constantly changing, and not always in predictable directions.
Migration of a refinery's DCS provided an opportunity to reconfigure and consolidate the control rooms and operational management system.
Process plants are run according to operational procedures. These procedures consist of a set of tasks that are executed in a consistent manner to achieve a specific objective, such as starting up, shutting down or transitioning a unit as part of making a product.
The new CSPC (CNOOC and Shell Petrochemicals Company Limited) petrochemical complex at Daya Bay in southern China is one of the world's largest process industry projects (see box, Figure 1 and Table). It has a control system to match. Process Worldwide spoke to Johan Veerman, principal instrument and process control engineer at CSPC, about the challenges of managing such a huge job.
In times of abnormal operations, systems are configured to produce lots of data – humans are not configured to handle or interpret them. However, when presented with the right information, in the right context, during an abnormal condition, humans are able to do things machines cannot.
The Wyoming Trona Ore Mine and Refinery upgrade from Yokogawa Centum CS3000 to CENTUM VP-R5 involved two domains, 21 RIO and FIO field control stations, 17 operator stations, 6 engineering stations and 8 different plant servers
ISA S88.01 provides great benefit to users and vendors by solidifying batch operating models and standardizing batch control terminology. On the other hand, as befits an industry-wide standard, ISA S88.01 leaves great flexibility for individual users to apply their own project practices and implementation methodology. Even when utilizing ISA S88.01 models and terminology, many pitfalls remain for those who implement batch controls and recipe management without thinking ahead. Real-world project experience has demonstrated a number of design and implementation "lessons" which might be overlooked to the eventual grief of the batch engineer.
The S88.02 draft standard defines a means for depicting procedural control in master and control recipes. This depiction method is called a Procedural Function Chart (PFC). This standard depiction is based on the requirements of S88.01, technical report ISA-TR88.0.03-1996, user requirements, previous standards and commonly used procedure depiction methods in use today. PFCs can provide a common basis for the exchange of recipes, reduce the learning curve between control systems, and establish a common ground for improved human communication. This paper provides a brief overview of the development of PFCs, the rules for their use and some of the benefits expected by their adoption in the industry.
The case study in this paper illustrates the value of integrating front-end scheduling with a batch control system. Recipe changes, and addition of recipes, occur frequently in the target process. However, since both scheduler and batch packages were designed with the ISA-S88.01 model in mind, these packages could be tightly coupled (well integrated) – and, as a result, it is easy to add or change recipes. The front- end scheduler is not limited to performing scheduling; it also provides an easy-to-grasp real-time production status display which can help enhance efficiency and productivity.
As batch processes are automated, it is common to leave certain less essential field devices without automatic actuators. Thus, the initial control design must accommodate both automated and manual activities. Later, the manual field devices may be automated, either one-at-a-time or in related groups as equipment modules. These field changes, often occurring over a period of years, each require rework of the batch control logic, which can easily exceed the cost of the actuator. In response to this undesirable situation, a technique has been developed which permits the batch design to automatically modify itself, or evolve, to accommodate changes in field automation.
Six Sigma is a quality improvement methodology applied to improving any type of process. It is a methodology endorsed by and heavily integrated into several major chemical companies.
Key Performance Indicators (KPIs) are used in batch processing industries as measurements of production performance. Their use is one element in the current trend of real-time performance management. A single KPI used as the primary measurement of production can cause other dimensions of production performance lose importance. When multiple KPIs are used to measure a batch's production performance it can be difficult to reconcile differences between them for individual batches or for groups of batches. KPIs based upon meeting a target, or specification, measure absolute performance yet do not provide relative information regarding how a batch performed against its peers. The peer comparisons are important for monitoring variability of production performance, which is a critical factor in documenting ROI.
The application of DCS-based "advanced controls" is a common method of achieving enhanced performance from continuous processes such as refinery units. However, it is less widely recognized, but nonetheless true, that modern DCS systems can include other software tools for the significant improvement of batch plant productivity, product quality, and economic performance. Due to the fundamental processing differences between the two types of plants, unique batch "advanced control" features are required which are different from those used for continuous plants.

Standard Automation Methodology Improves Operations and Prevents Incidents by Enabling the Sharing of Best Practices Among Operators.
Process automation in oil refineries is undergoing major changes, driven by customers frustrated by what they consider to be slow and incremental advances from the main automation original equipment manufacturers (OEMs) in the industry. ExxonMobil has become a de facto industry representative and is driving vendors like Yokogawa and others to reevaluate how large-scale automation projects are implemented.
Supervisory control and data acquisition (SCADA) systems have been part of the process industries for many decades and cyber security measures need to grow as technology advances. SCADA systems are used in oil and gas pipeline and other remote control and monitoring applications, such as electrical transmission and distribution, and water/wastewater.
Many lubricant blending businesses find themselves in a challenging situation: there are opportunities to increase their overall business volume and profits by improving production flexibility, expanding their product slate and optimizing high-margin blends. At the same time, they find themselves constrained by current manufacturing limitations. However, launching a capital project for a significant manufacturing expansion may not be possible, and it may not be necessary.
Spectrometric technology can assess many critical characteristics about products, but it has limits. It can be challenging to determine when the line has been crossed
Machines can support humans when facing a stressful situation. Using a standards-based approach can reduce the likelihood of a problem escalating.
Honeywell and Yokogawa have both been producing Distributed Control System (DCS) platforms for decades, and both are very active in this area. In 1975, Honeywell introduced its TDC2000 platform and Yokogawa brought out CENTUM. These two competing systems emerged from a similar place, oil refining and petrochemical industries, so they started out with similar basic concepts and use cases in mind.
The accuracy of pH measurements depends upon maintenance; maintenance frequency largely depends upon the application. Understanding and addressing the causes of pH measurement difficulties comprise key to ensuring stable and accurate readings.
