Background and Objective: Ethylene oxide (EO) is a very toxic and dangerous substance with a high potential for explosion and fire. Ethylene oxide units are among the most hazardous units in petrochemical industries. This study was designed to analyze and model the consequences of ethylene oxide storage tanks explosion in one of Iran's petrochemical industries. Materials and Methods: In this s...
Steels/alloys are widely used in various aspects of human society, such as transportation and construction, machinery manufacturing, oil, chemical, petrochemical, marine, nuclear power industries, etc [...]
in this research degradation and mineralization of ortho-toluidine (ot) in the wastewater of petrochemical industries was investigated by uv/tio 2 process in a batch recirculating photo reactor. the influence of different variables such as initial ph, amount of tio 2 and initial concentration of ot on the reaction rate was investigated. in optimum conditions (1.75 g/l of catalyst, ph at 7 and i...
Petrochemical industry generates highly toxic effluents with a large variety of chemicals, being most of them recalcitrant and toxic such as: organic chlorinated compounds (mainly 1,2 dichloroethane) and volatile and semivolatile organic compounds. The most common wastewater treatment systems used in Mexico to treat this kind of effluents are activated sludge and aerated lagoons. Treatibility s...
BACKGROUND Petrochemical industry is one of the fastest growing industries. This industry has immense importance in the growth of economy and manufacture of large varieties of chemicals. The petrochemical industry is a hazardous group of industry generating hazardous waste containing organic and inorganic compounds. In spite of the present treatment process, the hazardous waste compounds are fo...
BACKGROUND Volatile organic compounds (VOCs) are human-made chemicals widely spread in the environment and produced by petrochemical industries and petroleum refineries. The aim of this research was to evaluate the distribution of VOCs in the ambient air of Mahshahr Petrochemical Complex, Iran. METHODS This study was a cross-sectional research performed in 2009. We used the method numbered 15...
