Reciprocating compressors play a key role in the today industry. They are vital machines in various units of industrial plants from air compression units to refineries, gas processing plants, petrochemical facilities, refrigeration systems, LNG units and so on. They are the most efficient and the most common type of compressor. Advantages of new technologies compared to old-fashion designs for ...

Very-large-scale-integrated (VLSI) chips have made a great impact on the development of advanced control systems. The paper highlights the basic features and architecture of Programmable Logical Controller (PLC), Distributed Control System (DCS) and Personnel Computer (PC) based system used in almost all industries like paper, chemical, petrochemical, sugar, and fertilizer etc. The factors affe...

With the rapid development of the petroleum industry, a large number of oil contaminants leaked into the soil in the petrochemical complex areas, gas stations, automobile factory and other places, which resulted in serious soil contamination. Micro-Biological degradation of oil pollution was the focus of the present study. Many hydrocarbon-contaminated environments were characterized by low or ...

Various organic solutions are used in many industries such as the petrochemical industry. The presence of moisture in those solvents results in poor insulation, corrosion of apparatus and catalyst poisoning. Therefore, the moisture content of the solvents must be reduced to less than several ppm. Since ion exchange resins have an ability to adsorb selectively polar substances fromnonpolar solve...

Catalysts play a pivotal role in modern industries, especially in the petrochemical industry, such as in the processes for production of advanced materials such as carbon nanotubes. Since the discovery by Iijima in 1991, carbon nanotube has received increasing interest worldwide owing to their unique structural, electronic and mechanical properties [1], and their promising applications in molec...

There has been a recent surge in the number of disasters and incidents in occurring in the process industry (e.g. the petrochemical, chemical, food and pharmaceutical industries). The reasons include defects in process-safety management (PSM); inadequate safety management systems in companies; inadequate knowledge among managers and insufficient information about the tasks undertaken and result...

We describe a constraint programming approach for a supplydelivery problem in the petrochemical industry, in which barges transport liquid material from supplier locations to downstream processing plants. The problem is to design a pickup-and-delivery route for each barge such that given minimum and maximum inventory levels at each location are met for a given fleet size. This optimization prob...

Inspector Systems is a specialist in manufacturing of tethered self-propelled pipe robots for internal inspection, non-destructive testing and machining of pipeline systems. Our industrial sectors, which originates from 30 year experience in the nuclear industry, are Gas & Oil (On-/Offshore, Refineries), Chemical, Petrochemical, Water etc. The pipe robots are able to get inserted through poor a...

Chromatography has developed from an analytical technology to a well-established separation process in industry. It is the method of choice for difficult separation tasks especially when temperature-sensitive components or species exhibiting very similar thermodynamic properties are involved. Large-scale industrial applications have been reported from different industrial fields, e. g. in the p...

For predictive control in industry often very long horizons for control error and manipulated signal are used because of the slow processes which take place in the petrochemical industry. In order to reduce the computational effort some commercial predictive control program packages offer the ability to reduce the number of points in both horizons but do not recommend how to select the points w...
