含硫原油加工对策的探讨

DISCUSSION ON PROCESSING SULFUR-CONTAINING CRUDE OILS

就中东含硫原油的性质和我国石油炼制的实际情况，提出了１０个加工流程方案，并以沙特轻油：沙特重油＝１：１的混合原油为例，进行了技术分析及经济评价。认为含硫原油加工最关键的是渣油加工路线，是脱碳还是加氢。渣油延迟焦化加工的方案投资低，经济效益较好；渣油加氢方案轻油产率高，无低价值难销副产品，利税值高，但因投资过高致使投资利税率偏低，然而与国外情况相比还有潜力可挖，可与脱碳方案经济效益持平，值得进一步推广应用。

The properties of Mid-East sulfur containing crude oils are different from the low sulfur content crudes in China, so the processing schemes should also be distinguished. Through the technical-economic evaluation, it is recognized that the selection of processing route, either decarbonization orhydrogenation, is important. Decarbonization route, taking the residue oil delayed coking as an example,which has the advantages of low investment and rather high economic effect, however, it accompanies withlow value products. Hydrogenation route, residue oil hydrogenation, has the advantages of producing highyield light oils with high qualities, the weakness is that the ratio of profit to investment is lower due to thecurrent high investment in China. Frond the development point of view, efforts should be made to lowerthe hydrogenation investment and to carry forward the application of hydrogenation route.
