abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
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...
According to the proposed regulation of the Ministry of Petroleum to support downstream petrochemical industries with emphasis on completing the value chain of methanol / propylene and due to the significant overcapacity of methanol production units in Iran and the uncertain trend in methanol price in global markets, methanol downstream projects has attracted the attention of many investors. In...
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
Determining the optimal level of oil and gas production from the upstream projects of the country is one of the main challenges in the formulation of Master Development Plans (MDP) for petroleum projects and impacts the return on investment and profitability of contracting parties, especially the contractor. In Iran's oil and gas contracts, since the development of the MDP is the responsibility...
Export of liquefied natural gas (LNG) is one of the basic needs of the Iranian oil, gas and petrochemical industry due to the severe sanctions conditions in Iran, restrictions on export of natural gas through pipelines and increased use of LNG in the energy basket of different countries. However, in recent years, despite some attempts to produce this strategic product, no concrete results have ...
the caspian sea contains great resources of oil and gas. the caspian sea is a 700- mile- long body of water in central asia, land located between azerbaijan, iran, kazakhstan, russia and turkmenistan. iran was challenges and opportunities in the caspian region. key question in this thesis includes three section that first question, opportunities of iran in the caspian region, second question ch...
This study aims to design a strategic model of talent management system in the petrochemical industry and by using Grounded Theory. The present study is part of exploratory research projects. the researcher has collected data with a qualitative approach with a careful review of literature and history of talent management, researches, articles and books of internal and external literature as wel...
introduction: construction phase in industries is a dynamic process that is naturally and intrinsically dangerous and as it becomes more complicated, the accidents rate also increases. one should note that without considering a model, one could not obtain useful and reliable information and method to prevent accidents. therefore, to achieve useful methods for preventing accidents, it is desirab...
in this thesis, structural, electronical, and optical properties of inverse pervskite(ca3pbo) in cubic phase have been investigated.the calculation have been done based on density functional theory and according to generalized gradiant approximate (gga) as correlating potential. in order to calculate the configurations, implementing in the wien2k code have been used from 2013 version. first of ...
