Whether you produce Petrochemicals, Inorganics or Intermediates, you are under constant cost and margin pressure to deliver products to your customer in a timely and efficient manner while maintaining safe and compliant operations. Additionally, you need to adjust to constant feedstock and energy prices and be able to provide the most profitable product mix to the market.
Yokogawa has been serving the bulk chemical market globally and is the recognized leader in this market. With products, solutions, and industry expertise, Yokogawa understands your market and production needs and will work with you to provide a reliable, and cost effective solution through the lifecycle of your plant.
The chemical industry is highly specialized, with plants producing intermediate products, out from raw materials, that, in turn, are used by other plants as inputs in their production of more advanced products. Each chemical company needs to carefully consider its positioning in a highly competitive marketplace.
Basic chemicals are usually produced in a continuous process that requires a highly reliable and robust control system. Here also, the CENTUM VP integrated production control system is the ideal solution which realizes a comfortable operation environment in response to process requirements, and provides a comfortable driving environment with a stable process control. The Exapilot online navigation tool provides operators with a strong support for reliable execution of non-routine operations such as shutdown and startup.
Production Control System: CENTUM VP
The single Integrated Control and Safety System (ICSS) database simplifies engineering.With graphics, alarm windows, and system status screens all having the same look and feel, operation is also easier.
Safety Instrumented System: Prosafe-RS
Yokogawa offers a full-lineup of safety instrumented systems from solid-state and hard-wired types to fully integrated DCS-SIS integrated types, covering all safety integrity levels (SIL 1 to 4) for the chemical industry.
Operation Efficiency Improvement: Exapilot
Exapilot is an online navigation tool that guides operators step by step through plant operating procedures.
Using Exapilot, Standard Operating Procedures (or SOPs) are created in a standardized form. SOPs improve efficiency and reduce the total cost of ownership by reducing or eliminating human errors.
Highly responsive analytical systems contribute to accurate measurement of product/intermediate property, helping chemical companies meet tighter quality control and environmental regulations.
“Install and forget” digital field instruments deliver stable and accurate process measurements with low installation cost, near-zero maintenance and self-diagnostic intelligence. As a true leader in the process automation industry and its related technologies, Yokogawa brought the world’s first FOUNDATION fieldbus™ enabled device to market and has since developed a complete range of FOUNDATION fieldbus™, HART, and Profibus protocol instrumentation, in addition to ISA100.11a compliant wireless communication products.
Hydrogen is the simplest and smallest atomic element. Water, acids, bases, and the immense family of organic compounds all contain hydrogen. Even though hydrogen is not corrosive, it can cause problems for pressure transmitters through Hydrogen Permeation.
Caustic soda and hydrochloric acid, produced in electrolyzer plants, are fundamental materials used in varieties of industries; chemicals, pharmaceuticals, petrol-chemicals, pulp and papers, etc. Profit is the result of the effective production with minimized running / maintenance cost. Proper control of the process brings you stabilized quality of products with the vast operational profit.
Electrolysis plants create hydrogen and chlorine from a brine solution. Chlorine gas generated from the anolyte of the electrolysis tank generally contains between 0.5 to 2.0 vol% H2O. The sample is then cooled and filtered to remove brine, subsequently coming out as wet chlorine gas. The wet gas is sent to a drying tower where it is treated with sulfuric acid to get moisture down to the ppm level.
Measurement and control of Heat Exchanger Leakage can help prevent costly maintenance, repair and downtime. The simple, essentially maintenance-free measurement of condensate conductivity will give the operator information necessary (or provide automatic control) to prevent severe damage to the boiler should a breakthrough of the heat exchanger occur.
If a sensor is not operating, the manufacturer cannot detect moisture in the chlorine and must stop the process. Unfortunately, sensors can deteriorate and deliver inaccurate measurements due to contact with the process.
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.
Storage tanks are used in a variety of industries ranging from holding crude oil to holding feedstock for vinyl chloride monomer (VCM).
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.
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.
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. 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. Open loop vs Closed loop implementation is also presented.
Rohm and Haas Company is one of the world's largest manufacturers of specialty materials, including adhesives, sealants, coatings, monomers, electronic materials, inorganic and specialty solutions, and ion exchange resins. Founded in 1909 by two German entrepreneurs, Rohm and Haas has grown to approximately $6 billion in annual revenues.
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.
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.
