提高柴汽比、汽油降烯烃的有效途径──大庆原油加工流程探讨

Planning Process Scheme to Increase Diesel/gasoline Ratio and Reduce Gasoline Olefin for Processing Daqing Crude

介绍了催化裂化、延迟焦化、加氢裂化等提高轻油收率的主要技术手段 ,以 1 0 0 0万t a规模的大庆原油炼油厂 3种不同加工流程的主要产品产量、柴汽比、汽柴油产品质量、技术经济评价等几方面的对比结果 ,论述了加工流程对提高柴汽比和产品质量的影响 。

Fluid catalytic cracking, delayed cracking and hydrocracking processes to increase light oil yield are reviewed. Based on three typical flow schemes for processing Daqing crude oil of 10 Mt/a, the paper discusses the effect of flow schemes on increasing diesel/gasoline ratio and up-grade products quality, and suggests restructure way for existing refineries by comparing products yield, diesel/gasoline ratio, gasoline,diesel quality and economic evaluation.
