Chemical plants rely on continuous and batch production processes, each posing different requirements for a control system. A continuous process calls for a robust and stable control system that will not fail and cause the shutdown of a production line, whereas the emphasis with a batch process is on having a control system that allows great flexibility in making adjustments to formulas, procedures, and the like. Both kinds of systems need to be managed in available quality history of product, and to be able to execute non-routine operations. With its extensive product portfolio, experienced systems engineers, and global sales and service network, Yokogawa has a solution for every plant process.

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. 

Overview:

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.

Overview:

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. 

Overview:

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.

Overview:

The aim of this work is to present a proposal for implementation of a support framework for abnormal situation management in the chemical process industry. A main feature of the technology developed is that it takes advantage of existing software packages that are familiar to plant engineers (e.g. Plant Information System) and a commercial process simulator. On the basis of three sources of information (a historical database, a HAZOP analysis, and a first principles plant model), the support framework is developed and easily implemented into the real plant. It consists of a preprocessing module, which performs a variety of key tasks using plant data such as data reconciliation, filtering, and denoising. Some of the outputs of this preprocessing module are the inputs of the fault diagnosis system (FDS). This FDS is a combination of a pattern recognition approach based on neural networks and a fuzzy logic system (FLS) in a block oriented configuration. The case study used to demonstrate the FDS implementation corresponds to a real petrochemical plant.

Overview:

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.

Overview:

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.

Overview:

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.

Overview:

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.

Overview:

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.

Overview:

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.

Overview:

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.

Overview:

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.

Overview:

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.
