使用Aspen Plus模拟软件对33万t/a废旧轮胎裂解油加氢装置的2种汽提工艺方案(双塔方案和单塔方案)进行对比,并讨论了热、冷低分油温度(Th,Tc)以及汽提蒸汽(1.0 MPa,250 ℃)总耗用量(mst)对硫化氢脱除效果及汽提塔塔底流出物收率(Y)的影响。结果表明:在热、冷低分油进料条件均相同前提下,这2种汽提方案的塔底流出物含硫化氢量均低于10 μg/g,Y均大于93.0%;权衡考虑装置脱硫效果及能耗,选择mst为0.36 t/h较佳;单塔工艺方案优于双塔方案,前者不仅运行更加稳定、操作弹性更大,而且主要设备总投资成本仅为后者的85%,尽管其当量综合能耗比后者的高0.08 MJ/t。

In response to the quality upgrade requirements of blending components of National Ⅵ B gasoline products,the 1.2 Mt/a heavy oil catalytic cracking (RFCC) unit of CNOOC Zhongjie Petrochemical Co Ltd began to add the LC-6 type gasoline olefins reduction catalyst since October,2023,which developed by Lanzhou Chemical Research Center,PetroChina. The results showed that after using the LC-6 type gasoline olefins reduction catalyst,the volume fraction of olefins in RFCC gasoline reduced from 31% - 34% to 26% - 29%,and met the quality upgrade requirements of blending components of National Ⅵ B gasoline products and ensured the finished ex-factory gasoline products up to standard (its volume fraction of olefins not more than 15%). Compared with the blank calibration period,under the condition that the unit consumption of the LC-6 type gasoline olefins reduction catalyst reduced to 1.21 kg/t and the processing raw material was inferior heavy oil with high metal content,then the yields of dry gas,liquefied gas,gasoline,slurry and total liquid of this above RFCC unit decreased by 0.29,0.24,1.90,0.49and 0.14 percentage points,respectively. However, the yields of coke and diesel increased by 0.43 and 2.49 percentage points,respectively. Meanwhile,the volume fraction of olefins in RFCC gasoline reduced by 5 percentage points,and the volume fraction of propylene in liquefied gas increased by 1.29 percentage points.
