Customer Challenge

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.

Our Solutions

Chemical Industry Value Chain

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.

Enabling Technology

Production Control System: CENTUM VP

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

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

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.


Process Analyzer

Analyzer
Highly responsive analytical systems contribute to accurate measurement of product/intermediate property, helping chemical companies meet tighter quality control and environmental regulations.


Field Instruments

Field Instruments
“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.

Prezentare generală:

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.

Prezentare generală:

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.

Prezentare generală:

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.

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. 

Prezentare generală:

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.
