加工中质高硫原油的新炼油厂设计理念及方案

Design philosophy and scheme of a grass-root refinery processing of medium high-sulfur crude oil

大连长兴岛石化园区的建设为中国石油天然气集团公司大连石化分公司的进一步发展提供了新的机遇。新建炼油厂设计加工来自中东地区的中质高硫原油,API°为30.6,硫质量分数为2.67%。其重油加工设计以加氢路线为主,以脱碳路线为辅的方案,以增强原油适应能力。规划生产高附加值芳烃产品,高档润滑油基础油产品,汽柴油产品质量定位为欧V标准,充分利用C3,C4轻烃资源发展化工。采用重质原料进行POX制氢,充分回收炼油厂氢气资源,降低氢气成本,分析了与石化园区开展合作的意义及优势,项目具有较好的盈利能力。

The construction of Dalian Changxing Island Petrochemical Park provides a new opportunity for further development of PetroChina Dalian Petrochemical Company. The grass-roots refinery is designed to process medium high-sulfhur crude oil from Middle East with 30.6°API and 2.67% sulphur. Its heavy oil is mainly processed by the hydrogenation processes, which are supplemented by decarburization to improve the adaptability of crude oil. The refinery is planned to produce high value-added aromatics products, high-grade lube base oil products, fuel oil products meeting Euro V standards as well as petrochemical products by using C3 , C4 light hydrocarbons resources. The hydrogen is produced from heavy feedstock by POX process, and the hydrogen resources of refinery are fully recovered to reduce the hydrogen costs. The significance and advanta- ges of cooperation with the Petrochemical Park are finally analyzed, which shows that the project has a good profit-making potential.
