摘要
直馏石脑油是重整装置的主要原料,但通常存在着上游供料不足的问题。在加氢裂化石脑油和焦化石脑油不足时,可以考虑用催化裂化石脑油作补充。工业实践表明,当催化裂化石脑油掺入比小于20%的情况下,催化裂化石脑油可以直接进重整预加氢装置,生产出满足重整工艺要求的原料。这可以在一定程度上缓解重整装置低负荷运行及全厂氢气供应紧张的难题,同时可以缓解出厂汽油烯烃和硫含量高的问题。
Straight-run naphtha is the main raw material of reforming unit, but there is usually insufficient upstream feed. When hydrocracking naphtha and coking naphtha are insufficient, FCC naphtha can be considered as a supplement. Industrial practice shows that when the blending ratio of FCC naphtha is less than 20%, FCC naphtha can directly enter the reforming pre-hydrogenation unit to produce raw materials that meet the requirements of reforming process. This can alleviate the problem of low load operation of reforming unit and the shortage of hydrogen supply in the whole plant to a certain extent, and also alleviate the problem of high olefin and sulfur content in gasoline.
