MIP技术加工加氢渣油的优势分析

ADVANTAGE ANALYSIS OF MIP TECHNOLOGY FOR PROCESSING HYDROGENATED RESIDUE

对以加氢渣油为原料的工业MIP装置与常规FCC装置的液体产品收率与产品性质进行对比分析。结果表明：与常规FCC技术相比，MIP技术即使在加氢渣油原料性质略差时，其液体产品收率仍提高1．35～3．23百分点，汽油收率较高，油浆产率较低；而且所产汽油的硫含量低、烯烃含量较低、辛烷值较高。MIP技术具有独特的串联双反应区反应系统，重油转化能力高，汽油品质好，在加工加氢渣油时比常规FCC技术更有优势。

The data of liquid yields and product qualities of MIP unit were compared with the results of traditional FCC units,all of which use hydrotreated residue as feedstock. The commercial data show that MIP technologies, although processing poorer quality of hydrotreated residue feedstocks, has higher total liquid yield, higher gasoline and lower slurry yields. Compared with the results of conventional FCC technologies, the liquid yield of MIP is higher by about 1.35 3.23 percentage points. MIP technology can achieve gasoline with lower olefin and sulfur content and higher octane number. MIP process based on the unique double reaction sections in series in one riser reactor intensifies the heavy oil conver- sion,and improves the quality of gasoline, and has more advantages in processing hydrotreated residue than common FCC.
