新型化工型炼油厂总加工流程的优化

CONFIGURATION OPTIMIZATION OF NEW PETROCHEMICAL COMPLEX

以典型沙特混合原油为研究对象,通过分析原油组成、加工工艺路线以及化工原料优化等,探讨不同原油加工方案对炼化一体化总加工流程的影响。结果表明:在“以多产化工原料为目标,宜烯则烯,宜芳则芳”的原则下,可以统筹炼油工艺优化和化工产品生产;在“新型化工型炼油厂的总加工流程”中选择重油催化裂解、二次柴油加氢处理、C_(4)馏分综合加工、石脑油正异构分离等工艺技术,可减少成品燃料油的产出,多产化工原料,适量增产芳烃产品;通过优化炼化一体化的产品方案,可以提高全厂经济性、降低成本、增强企业竞争力。

Taking typical Saudi blended crude oil as the research object,this paper discussed the influence of different crude oil processing schemes on refining-chemical integration total processing scheme through analyzing its composition,processing route and chemical raw material optimization.The results showed that the optimization of oil refining process and the production of chemical products could be coordinated under the principle of“appropriate olefins feedstock produces more olefins and appropriate aromatics feedstock produces more aromatics”in order to realize overall optimization of refining and chemical products production.In the new chemical refinery,the technology like DCC,RLA,C_(4)process and normal and isomeric naphtha separation could improve the product structure,reduce the fuel oil production,and product more chemical raw materials and appropriate aromatic products.By optimizing the product scheme of refining and chemical integration,we can improve the whole plant economy,reduce the operating cost and enhance the enterprise competitiveness.
