In 2018, the worldwide consumption of meat was 346.14 million tonnes, and this is expected to increase in future. As increases, use packaging materials along with it. Petrochemical which are widely used processing industry, take a long time regenerate biodegrade, thus they adversely affect environment. Therefore, necessity for development eco-friendly processing, easily degradable recyclable, c...

In this work, a multiperiod MINLP model is proposed for the supply chain optimization of a petrochemical complex. Nonlinear, semi-rigorous models have been included for main plants in the site, allowing the determination of process operating conditions and product properties. Intermediate and final product storage and shipping are considered. Binary variables are associated to intermittent prod...

Since global warming due to greenhouse gas emissions is no respecter of geographical boundaries of countries, concerted mitigation activities such as Clean Development Mechanism (CDM), are suitable. In this mechanism, some developed countries can gain certified emission reduction credits from emission reduction actions undertaken in developing countries. Thus, the data of greenhouse gas emissio...

the purpose of this study is to evaluate effect of porter`s competitive strategies tomeet customer market orientation needs in petrochemical firms. given the numbers ofproducts of this company, this study examine polyethylene products, so the impact of 3porter`s strategies, differentiation strategy, focus strategy, cost leadership strategy,evaluate in response to market orientation needs of thi...

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...

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...
