【摘要】：介绍了焦化加热炉在线清焦技术在中国石油天然气股份有限公司乌鲁木齐石化分公司延迟焦化装置的应用过程以及注意事项,通过应用在线清焦技术,在相同工况下加热炉炉管壁温度最高降低约100℃,燃料气消耗量降低约200 m3/h,炉膛温度最高下降了42℃,炉管压力约降低0.15 MPa,有效延长了加热炉运行周期。对多次在线清焦给加热炉、焦炭塔和分馏稳定系统带来的不良影响进行了分析,提出了降低不良影响的相关措施。由于加热炉清焦对设备和生产操作影响大,也存在一定危险因素,提出了应当尽可能减少在线清焦频次,制定在线清焦界面条件也非常有必要。
[Abstract]:The online application process of coking furnace coke cleaning technology in Urumqi Petrochemical Company, the PetroChina Co Ltd of the delayed coking device and the matters needing attention, through the application of online coke cleaning technology, in the same condition the wall temperature of the furnace tube is reduced up to about 100 DEG C, fuel gas consumption is reduced about 200 m3/h, the temperature dropped 42 degrees maximum about 0.15 MPa, reduce the tube pressure, prolong the operation cycle of the heating furnace. On the number of online coke cleaning for heating furnace, influence of coke tower and fractionation stabilization system were analyzed, and puts forward relevant measures to reduce the adverse effects. Due to the heating furnace coke cleaning effect on equipment and production operation, there are some risk factors, should be made as far as possible to reduce the online coke cleaning frequency, making online coke cleaning interface condition is also very necessary.
