[Abstract]:By using the method of hydrogen pinch analysis, the basic distribution scheme of hydrogen flow unit in refineries is obtained, and then the optimized hydrogen pipe network scheme is determined by combining with the plan optimization model, and the economic and technical indexes of the scheme are analyzed. The effectiveness of the evaluation scheme is evaluated. Taking an oil refinery in China as an example, the hydrogen system is optimized by the above scheme. The results show that the purity of hydrogen can meet the processing process requirements of the refinery by means of pinch point analysis. Combined with the plan optimization model, the network structure of hydrogen can be effectively optimized according to the production condition of the refinery, and the purpose of saving hydrogen and optimizing the processing scheme of crude oil in the refinery can be achieved, and after the optimization of the hydrogen system, the hydrogen can be saved by 16.6and the crude oil of poor quality can be processed. Reduce the cost of crude oil procurement and improve the economic efficiency of refineries.
