Optimal Management of a Hydrogen Network in a Petrol Refinery
نویسندگان
چکیده
This paper discusses different aspects of the optimization of the distribution of hydrogen in a petrol refinery through a network that connects production and consumption plants. Due to the lack of reliable information from the field measurements, a previous stage of data reconciliation is required. The hydrogen distribution problem can be formulated as a non-convex NLP one, which implies the possibility of local minima if standard non-global NLP algorithms are used. To avoid this situation, a reformulation is proposed in order to convexify the problem. Results corresponding to data from a refinery are presented.

Editor – We appreciate the comments of P.J. Landrigan concerning our article on the factors associated with elevated blood concentrations in children in Karachi, Pakistan (1, 2). In his editorial, however, he commented that the decline in the use of leaded petrol in Pakistan had resulted in declines in children's blood lead levels. Mean blood lead concentrations in schoolchildren had been repor...
متن کاملAN OPTIMIZATION APPROACH TO REFINERY STEAM MANAGEMENT WITH CONSIDERATION OF CO2 EMISSION
The importance of energy crisis and global warming necessitates presenting strategies in order to decrease the amount of emissions as well as fuel consumption in large and complex industries such as refineries and petrochemical industries. Generally, refinery steam networks are regarded as units which consume fuel enormously. In this paper, the steam network of Tehran Oil Refinery is considered...
