Abstract: Chemical storage tank leakage in petrochemical wharf is a serious economic, environmental and safety problem. Risk assessment is an effective way to identify chemical storage tank hazards and provides a guide for accident prevention in petrochemical wharf enterprises. Based on the characteristics of chemical storage tank zone, this paper proposes a real-time relative risk assessment m...

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...

The complex nature of the petrochemical industries necessitates an efficient decision on a large number of factors so as to optimally operate a plant. Production planning is an integral part of the petrochemical industry and requires the optimal selection of processes, production levels and products to maximize its profit. Previously an MILP formulation has been proposed for guiding the petroch...

The investigation of occupational Noise in a Petrochemical industry has been carried out. The noise levels were measured following standard procedure using calibrated sound pressure level meter Smart Sensor (Model AR854), Noise levels were measured at Gas plant, Olefin plant area, and Preform machine area of a petrochemical industry then questionnaires were designed to determine the health impa...

The competitive scenario in recent decades has imposed increasing levels of complexity and interdependence to companies, which try to respond to this challenge providing some organizational changes, such as collective arrangements. This article aims to understand the emerging collective competencies based on the mobilization of different working groups to make the turnaround maintenance (TM) po...

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...
