加工高硫原油使炼油工业面临含硫渣油、沥青和焦炭产品最终不可避免的硫排放问题。国内大型炼油厂在加工进口原油时 ,所产生的残渣要进一步加工利用。论述了可选择的三个非加氢方案。气化 (IGCC)方案是目前国外普遍采用的利用炼油厂废渣造气的渣油加工路线 ,延迟焦化加循环流化床锅炉和重交通道路沥青加硬沥青水浆两个方案对加工高硫原油的国内大型炼油厂具有现实的指导意义。可利用这些方案将销路不好的高硫渣油、沥青和焦炭转化为具有一定附加值的产品如电、蒸汽等
The processing of high-sulfur crude oil has left the refinery industry with the ultimate inevitable sulfur emissions from sour residue, pitch and coke products. Large domestic refineries in the processing of imported crude oil, the resulting residue to be further processed. Three alternatives to hydrogenation are discussed. Gasification (IGCC) scheme is currently widely used in foreign countries to make use of refinery residue gasification of the residue processing route, delayed coking plus circulating fluidized bed boiler and heavy traffic asphalt asphaltene plus asphalt slurry two programs to process high-sulfur crude oil The domestic large-scale oil refinery has realistic guiding significance. These solutions can be used to convert poorly-crafted, high-sulfur residual oils, bitumen and coke into products of certain added value such as electricity, steam, etc.
