Overview:

ENEOS Materials successfully achieved the world's first long-term autonomous operation of a plant using Yokogawa's AI. FDKPP saves energy and reduces operator workload while maintaining manufacturing quality.

Overview:

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.

Overview:

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.

Overview:

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.

Overview:

Storage tanks are used in a variety of industries ranging from holding crude oil to holding feedstock for vinyl chloride monomer (VCM).

Overview:

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. 

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:

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.
