Till now Chinese producers have not yet adopted the novel oxidation co-catalyst for manufacture of PTA. For this reason, SINOPEC has set up a project on R＆D of novel co-catalyst for oxidation of para-xylene, and the development work is jointly performed by the chemical plant subordinated to Yangzi Petrochemical Company （YPC） and YPC＇s Research Institute.展开更多

Different from optimization of product quality or calculation of generic energy conservation in most previous studies, the application of exergy analysis and exergy cost optimization in petrochemical industry is of great economic and environmental significance. Based on the main fractionator in Jiujiang Petrochemical Complex No. 2 FCCU, an enhanced exergy cost optimization under different operating conditions by adjusting set points of temperature and valves opening degree for flow control is studied in this paper in order to reduce exergy cost and improve the quality of energy. A steadystate optimization algorithm to enhance exergy availability and an objective function comprehensively considering exergy loss are proposed. On the basis of ensuring the quality of petroleum products, the economic benefits can be improved by optimizing the controllable variables due to the fact that exergy cost is decreased.展开更多
