M. E. Zeynali [email protected] Petrochemical Synthesis Group, Petrochemical Faculty, Iran Polymer and Petrochemical Institute (IPPI), P. O. Box: 14965/115, Tehran, Iran, Abstract In this study the diffusion coefficients for reaction components were determined for unimodal and bimodal pore size distribution and assuming transitional diffusion regime using a more realistic, Stewart-Johnson, m...

To investigate potential links between environmental exposure to petrochemical plant emissions and lung cancer, a population-based case-control study (LMRICS) was conducted in eleven Louisiana parishes bordering the Mississippi River. Cases and age, gender, and race-matched controls were interviewed regarding potential risk factors. Residential history was geocoded to provide indices of long-te...

There have been growing concerns regarding the limited fossil resources and global climate changes resulting from modern civilization. Currently, finding renewable alternatives to conventional petrochemical processes has become one of the major focus areas of the global chemical industry sector. Since over 4.2 million tons of acrylic acid (AA) is annually employed for the manufacture of various...

Biological treatment methods for the biodegradation of anthropogenic toxic pollutants are eco-friendly in nature and powered by a variety microbial enzymes. Green chemistry enzymes play crucial role catalyzing organic inorganic including azo dyes; polyaromatic hydrocarbons; lead; cyanides; aromatic amines; mono-, di-, polyphenols; polymers; mercury. Laccases form prospective group multifunction...

The increasing population, urbanization and industrial growth are causing serious environmental challenges including air pollution worldwide. According to WHO, the indoor and outdoor air pollution exposure has caused around 7 million deaths globally only in 2012. The major air pollution sources include transportation and petrochemical based industry. Motor vehicle repair workshops (MVRW) pose m...

A study on the impact mechanism of safety capacity in petrochemical base is carried out, according to system structure modeling and system dynamics simulation. The hierarchical structure model of 14 factors that affect the safety capacity in petrochemical base is built up. Safety management and emergency management are included in the first hierarchy. In the next hierarchy, there are three fact...

Aquatic environments are among the most vulnerable habitats that affect all Organisms. The Persian Gulf is home to numerous plant and animal species, biological safety at risk due its human activities. Traffic of oil commercial vessels in area, waste water, desalination, proximity industrial, refinery petrochemical units shores rivers, rigs, fishing, tourism activities potential hazards environ...

This paper addresses the strategic planning, design and optimization of a network of petrochemical processes under uncertainty and risk considerations. The problem was formulated as a two-stage stochastic mixed-integer nonlinear programming model (MINLP) with parameter uncertainty considered in process yield, raw material and product prices, and upper and lower product market demand. Risk was a...

Petrochemical-based plastics are widely used in modern society due to their high effective mechanical and barrier properties (Farris et al., 2009; Siracusa et al., 2008). However, petrochemical-based plastics have become an environmental concern as they are not biodegradable or recyclable. Replacing the petrochemical-based polymers with biopolymers which are renewable has become an attractive i...
