催化裂化加工苏丹高酸原油工业试验标定

摘要

Industrial test of processing Sudan high acid crude oil with 20×104 t/a wax oil catalytic cracking unit in Shtar science and Technology Group Co., Ltd. was calibrated. The results show that the direct processing of high acid crude oil with catalytic cracking unit is feasible, and it can play a double effect of atmospheric distillation and catalytic cracking; 99% of naphthenic acid in high acid crude oil can decompose in the riser under the environment of high temperature, which can avoid the equipment corrosion caused by the naphthenic acid in subsequent processing;Because crude oil residue and metal content are high, external heat collectors of the device must be fully run, and the amount of treatment need be decreased, catalyst deactivation easily appears after poisoning.%对山东石大科技集团有限公司20×104 t/a 蜡油催化裂化装置加工苏丹高酸原油的工业试验进行标定。结果表明，高酸原油进催化裂化直接加工是完全可行的，它可起到常压蒸馏和催化裂化双重效果；高酸原油中的环烷酸在提升管高温环境下99%发生分解反应，避免了环烷酸后续加工对设备的腐蚀；原油残炭高，金属含量大，装置必须全开外取热并采取降处理量操作，催化剂中毒容易出现失活。
