Pulp & Paper

PT. Tanjung Enim Lestari Pulp and Paper (PT. TEL) operates a pulp mill in Muara Enim, which is 130 km west of Palembang, the capital of Indonesia's South Sumatra province. This is the only pulp mill in the world to produce high-quality, bleached-hardwood kraft pulp solely from plantation grown Acacia mangium trees.

A virtual network system that securely connects OT-IT built on existing network resources.
Yokogawa experts monitor the network remotely like customer's information system department.

• Yokogawa installed a B/M9000CS quality control system with various cross direction profile control functions.
• The installation improves product quality and efficiency at pulp & paper mill.

• Exaquantum Achieves $2 Million in Annual Savings for CENIBRA Pulp & Paper Plant.
• Following an upgrade to the CENTUM CS 3000 Production Control System, leading pulp and paper supplier CENIBRA saw the potential for further savings and efficiencies through tighter control of the production process.

To enable central control of the entire plant, all of its subsystems are integrated with Yokogawa's CENTUM VP DCS.

Yokogawa's unique simultaneous, dual-frequency excitation method used in the ADMAG TI magnetic flowmeter can enable tighter control, faster response, larger quantity of end product per batch, reduced cost, and higher profitability.

Drying is an important part of the papermaking process that evaporates the remaining water in the wet paper web. This is performed with a dryer, and the humidity control in this dryer is essential to maintaining high paper quality (e.g., strength, paper surface) and high heat energy efficiency.

With the high temperatures, pressures, and levels of dissolved organics that are encountered, the ADMAG AXG flow meter design is ideal for use in all phases of the chemical recovery process.

The treatment of wastewater from pulp and paper plants is a serious environmental concern. Yokogawa's submersion holder with an ultrasonic+air-jet cleaner (customized product) can reduce the manual cleaning frequency to just once every one or two months.

Ideal for various tank and vessel level measurements, diaphragm seal systems with compensating capillaries set a new standard for high performance, safety, and reliability.

Reverse osmosis (RO) is a separation process that uses pressure to force a solution through a membrane that retains the solute on one side and allows the pure solvent to pass to the other side. More formally, it is the process of forcing a solvent from a region of high solute concentration through a membrane to a region of low solute concentration by applying a pressure in excess of the osmotic pressure.

• Oil level measurement of diesel tanks that feed fuel to their diesel generator's which are at three locations and 400 meters apart from each other.
• Also to measure level , pressure and flow to and from their main storage yard.

The kraft process, also known as kraft pulping or the sulfate process, is a technology for conversion of wood into wood pulp that consists of almost pure cellulose fibers. Today, the kraft process is used in approximately 80% of paper production.

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.

The quality of paper for printing or writing should be high and it depends on many parameters. Cobb is one of the parameters, which requires control. Using a retractable fitting, this optimum pH level can be achieved by using Yokogawa's 4-wire pH Analyzer with a suitable, retractable fitting and sensor. Since a separate controller is not required for the dosing pump, this solution provides a cost-saving.
 

Problems at the wet end of a paper machine can rarely be corrected downstream. That is why monitoring and controlling pH in pulp stock is critical to the paper-making process. Essentially, at every stage in the manufacture of paper, correct pH values play a vital role. Variations in the pH value at the headbox have a negative effect on the quality of the paper produced. Proper monitoring ensures minimizing plugging and fouling problems that occur with pH measurements in paper mills. 

Yokogawa's digitalYEWFLO Reduced Bore Type Vortex Flow meter features a cast stainless steel body and a concentric reducer and expander that enable stable flow rate measurements in low-flow conditions. This expands the range of measurements that can be performed, from the higher flow rates down to the lower end of the flow span, which is normally difficult for Vortex Flow meters, and ensures stable and accurate flow rate output.

A belt conveyor fire detection solution employing the DTSX distributed optical fiber temperature sensor can greatly reduce crises that can threaten a company's survival.

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.

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.

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.

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.

Smart devices, like Yokogawa’s line of Total Insight transmitters and flowmeters contribute to Digital Transformation during operations and throughout the lifecycle of the instrument.

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.

Discovering your Baseline with OT Security Risk Assessment

Vibrating element (VBE) type gas measurement devices measure refinery reformer stream compositions, power generator hydrogen purity, centripetal compressor gas inputs, process heater fuel gas quality, and others in multiple process control environments.

Optimizing the maintenance cycle is not always straightforward. In some cases, cleaning once a week is sufficient and other processes may require every 8 hours.

Learning these four lessons will help you improve your engineering skills and most importantly extend the life of your pH sensors.

Select the correct pH glass and reference type to improve your pH sensor lifetime and you can limit or even eliminate the effects of temperature and pressure on especially the reference sensor.

The lifetime of a pH sensor has a significant impact on the overall annual costs of a pH measuring loop. Optimizing four key factors will decrease these costs and optimize process control and overall plant efficiency.

Kind of. Calibration itself will not extend the life of a sensor, however, a sensor that is not calibrated properly can cause unreliable measurements - that are often misdiagnosed leading to unnecessary replacements.
