OR YEARS, PROCESS SIMULATION WAS limited to the petrochemical industry and other related chemistries. Today, several simulation packages include aqueous thermodynamic capabilities that open process simulation up to a wide range of additional applications. This article will look at the theory of aqueous chemical equilibrium, its application to process simulators, and the application of simulatio...

Petrochemical plants are increasingly faced with the need to upgrade their control centers to support the installation of more advanced control systems and to better protect operations personnel in the event of catastrophe. Plants often take advantage of this opportunity to consolidate existing control rooms into a central facility, in hopes of improving plant-wide communications, increasing op...

In this work we investigated the structure of the iron-stimulated surface tension reducing substances produced by P. citronellolis 222A isolated from a 17-years old landfarming used for sludge treatment in petrochemical industries and oil refinery. Its mass spectrum differs from P. aeruginosa spectrum, indicating that the surface tension reducing substances produced by P. citronellolis can be a...

The course of 20-year studies on the health of the population of Ptock and its neighbourhood has been discussed as regards environmental pollution generated by refinery-petrochemical plant. Analysis of environmental factors and general principles of health-promoting phenomena were of particular concern. This paper demonstrates an increase in options of environmental factors in studies on health...

background & aims of the study: petrochemical industry is an important industry in the economic development of the country that causes employees have exposure with several kinds of contamination. the aim of this study was semi-quantitative assessment of the health risk of occupational exposure to chemical materials and investigation of spirometry indices between employees of petrochemical indus...

The investigation of occupational Noise in a Petrochemical industry has been carried out. The noise levels were measured following standard procedure using calibrated sound pressure level meter Smart Sensor (Model AR854), Noise levels were measured at Gas plant, Olefin plant area, and Preform machine area of a petrochemical industry then questionnaires were designed to determine the health impa...

Petrochemical industry is a strategic for nation because it has big impact on society at large. derivative products are an inseparable part of our modern life. With the development technology, humans can synthesize innumerable combinations petrochemical molecular structures to obtain materials with certain properties suitable final be made, from clothing, packaging, pharmaceutical, households, ...
