摘要
介绍大庆分公司炼油厂延迟焦化装置扩能改造情况 ,内容包括 :柴油系统的换热流程优化、空气冷却器改造等。装置处理量由原来的 1.0Mt/a提高至 1.17Mt/a。此改造方案不增加设备 ,仅靠降低装置循环比及局部改造瓶颈部位 ,改造后循环比降至 0 .3,总液体收率提高 2 .3% ,年净利润达 15 43× 10 4RMB $。
Capacity expansion revamping of the delayed coker in Daqing Company is introduced. The description includes the heat-exchange flow scheme optimization of diesel system and the modification of air cooler, etc. Capacity of the unit has been increased from 18 000 b/d to 21 200 b/d by decreasing the recycle ratio and modifying some local bottlenecking positions, without adding any new equipment. After revamping, recycle ratio has reduced to 0.3 and total liquid yield has increased by 2.3%. Net annual economic benefit has reached 1 543×10 4 RMB yuan.
