OBJECTIVE To evaluate possible adverse reproductive outcomes in an area adjacent to a petrochemical plant in southern Brazil. METHODS A review of 17,113 birth records of the main hospital of the municipality of Montenegro, southern Brazil, from 1983 to 1998 was carried out. Three groups of cases were selected: (1) newborns with major congenital malformations; (2) newborns with low birth weigh...
The equilibrium chemical reactions taken place in a converter reactor of the Khorasan Petrochemical Ammonia plant was studied using the minimization of Gibbs free energy method. In the minimization of the Gibbs free energy function the Davidon– Fletcher–Powell (DFP) optimization procedure using the penalty terms in the well-defined objective function was used. It should be noted that in the DFP...
Background and purpose: It is likely that industrial workplaces increase the chance of developing obesity and cardiovascular disease risk factors in the employees. The aim of this study was to compare obesity and some health markers between male employees of gas refinery (first exposure group) and petrochemical staff (second exposure group) compared to non-industrial male employees of general p...
Based on the analysis of the theories of value chain and multinational merger and acquisition, we research the merger and acquisition of petrochemical industries based on value chain, according to the trait of the value chain of the petrochemical industries. And we propose the implementation process and the integration method for the merger and acquisition of petrochemical industries based on v...
In petrochemical plant facilities handling highly inflammable and combustible substances, it is necessary to preferentially review the frame type (closed or open) of facility with consideration various fire conditions that may arise depending on substances being handled. Accordingly, a simulation was carried out in this study for different by assuming three types, spatial temperature distributi...
Background and Objectives: Wastewater contains various pathogens including viruses, bacteria, fungi, etc. These microorganisms can easily become airborne during normal operations of wastewater treatment plant and contaminate the neighborhood environment. The aim of this study was to investigate the type and density of bioaerosols in a petrochemical wastewater treatment plant in Iran. Materials...
