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.

  • 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.
  • Smooth conversion of existing controls solely by customer
  • Lowered cost of ownership
  • Integration of previously independent water usage functions into automatic control system
  • Reduced operators' workload and environmental impact

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


El vapor es todavía uno de los métodos más populares que proporcionan una fuente de energía para un proceso y sus operaciones asociadas. Las mediciones más precisas y confiables que se realizan, las decisiones más informadas pueden ser tomadas afectando los costos y la calidad del producto.


El método único de excitación simultánea de doble frecuencia de Yokogawa y el método opcional de excitación de doble frecuencia mejorada pueden ofrecer beneficios en esta aplicación que puede resultar en un control más estricto, una respuesta más rápida, más producto final por lote, mayores beneficios y un ahorro directo de costos para el cliente.

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.

Industry:Pulp & Paper


La mejora continua de la tecnología en curso en la industria de pulpa y papel sirve para obtener el mejor rendimiento posible. El desempeño mejorado de la planta se traduce en la mejora de la calidad y menor costo, al mismo tiempo una operación de la planta amigable con el medio ambiente.


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.


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.


El nuevo medidor de flujo magnético digestor activa la medición de flujo exacta y estable de la línea de circulación de alcohol negro, ayudando al usuario a estabilizar el grado de cocción que determina la calidad del chip proceso de digestión.

  • 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.


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.


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. 


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. 

Documentación Técnica

Yokogawa ha recorrido un largo camino en hacer que su mensaje sea claro en el mundo de la automatización de procesos. El año pasado, la compañía se embarcó en una campaña global de marketing a gran escala para que los clientes conocieran el enfoque de la compañía en la confiabilidad del sistema, su seguridad, constancia y durabilidad. Denominado "Vigilancia", la campaña creó un mensaje unificado para la empresa y en gran medida ayudó a aumentar la difusión de la marca Yokogawa y la filosofía de la empresa.


Los usuarios finales de procesos automatización están bajo más presión para hacer más con menos. La situación económica actual hace que muchos proyectos de capital de automatización estén en espera. Con los presupuestos de capital más limitados que nunca, los usuarios en lugar de enfocarse en los presupuestos de operaciones (en donde también la reducción de costos es una preocupación clave), o en las inversiones de automatización con un rápido retorno de inversión.


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.
