A health risk assessment for the Lin-Yuan Petrochemical Industrial Complex (LYPIC) in southern Taiwan was conducted in this study. The main aims of the study were to develop an emission inventory for the 21 processing plants in the LYPIC, conduct hazard identification based on the emission inventory, perform an exposure assessment by applying air dispersion modeling to obtain the annual average...
The objective of this paper is the development and solution of nonlinear and mixed-integer (MIP) optimization models for real-world planning and scheduling problems in petroleum refineries. Firstly, we present a nonlinear planning model that represents a general refinery topology and allows implementation of nonlinear process models as well as blending relations. The optimization model is able ...
The Technical University of Madrid (UPM) and REPSOL YPF are collaborating in the improvement in the estimation of the emiss ion factors for refinery flares. Flaring is an unavoidable process in the refining activity, both for safety reasons during upset processes (start-up, shut down, system blow-down) and when managing the disposal of waste gases with hydrocarbon from routine operations. The o...
the lack of a structured anticipating about high usage product of the national petrochemical company, has forced this company to buy forecasted price from foreign countries. prevent the outflow of foreign exchange and tolerance of political factors such as sanctions in this field requires a forecast of prices in our country. due to the chain-like nature of the petrochemical products, and the ab...
