摘要
采用通常的渣油加氢脱硫 重油催化裂化 (ARDS/RFCC)方案加工伊朗常渣 ,轻油收率为 73 6 1% ,LPG和轻油总收率达 83 6 0 % ,但由于ARDS投资和操作费用较高 ,使得该方案投资利润率并不高 ;采用渣油预处理 加氢处理 重油催化裂化 (ROP/RHT/RFCC)方案加工伊朗常渣 ,尽管LPG和轻油总收率比ARDS/RFCC方案低 2 0 3个百分点 ,但由于采用ROP工艺大大减少了RHT的投资和操作费用 ,使总投资降低 6 1亿元 ,总操作费降低 6 6 2 1万元 /a ,因而使得该方案投资利税率比ARDS/RFCC方案高 2 5 % ,投资利润率比ARDS/RFCC方案高 9% ,投资回收期比ARDS/RFCC方案短
Iranian atmospheric residuum was processed with normal scheme of hydrodesulfurization/RFCC,the recovery ratio of light oil was 73.61%,the total recovery ratio of LPG and light oil could reach to 83.60%,but because of higher investment and operation costs of the scheme,its profit investment ratio was not high.When Iranian atmospheric residuum was processed with scheme of Residual Oil Pretreating(ROP)/hydro treating/RFCC,although LPG and light oil was lower for 2.03% than the former scheme,because the process of ROP greatly reduced the investment and operation costs of hydro treating,therefore the total investment cost was reduced for 610 millions Yuan(RMB),and the total operation cost was reduced for 66.21 millions yuan(RMB) per year,thus the profit investment ratio was higher for 9% and the investment payment time was shorter for 10 months than the former scheme.
