【摘要】：以某規(guī)劃新建煉油廠研究方案為例,提出催化裂化輕循環(huán)油(LCO)總加工流程優(yōu)化的新思路,根據(jù)LCO不同餾分段的組成特點及硫化物脫硫難易程度分餾為:LLCO(小于260℃輕餾分)、MLCO(260~340℃餾分)及HLCO(大于340℃餾分)。其中,LLCO進柴油加氫精制裝置,而富含多環(huán)芳烴的MLCO和HLCO則分別進加氫裂化裝置和渣油加氫裝置,增產(chǎn)重整料和催化裂化原料,因此在柴油產(chǎn)品產(chǎn)量降低的同時間接地增加汽油和芳烴產(chǎn)品的產(chǎn)量。結果表明,與基礎方案相比,優(yōu)化方案的汽油產(chǎn)量增加415.6kt/a,對二甲苯和苯分別增加33.3kt/a和14.7kt/a,柴油產(chǎn)量減少774.0kt/a,全廠柴汽比由1.38降至1.04,降柴汽比效果顯著。
[Abstract]:Taking the research scheme of a newly built refinery as an example, a new idea of (LCO) total process optimization for FCC light circulation oil is put forward. According to the composition characteristics of different fractions of LCO and the easy degree of desulfurization of sulfides, the fractionation of: LLCO (is less than 260 鈩，
