摘要
分析了中国石油四川石化800 kt/a乙烯装置高负荷运行时,脱丁烷塔塔釜再沸器运行周期短、塔釜产品中碳四组分损失高的原因。对结焦过程进行了分析。结合实际操作经验对工艺参数进行优化,达到延长再沸器运行周期的目的。根据工艺流程及现场再沸器的实际情况,找出了运行周期缩短的主要原因,并实施了优化措施。从而保证了乙烯装置稳定高效运行,达到了增加装置产能、降低能耗、提高总体经济效益的目的。
The reasons for the short operating cycle of bottom reboiler and the high loss of C4 components in bottom product of the debutanizer in the 800 kt/a ethylene plant at PetroChina Sichuan Petrochemical Company Limited during high-load production were analyzed,and the coking process was analyzed.The process parameters were optimized according to practical operation experience,and the goal of prolonging the operating cycle of reboiler was achieved. According to the process flow and the actual situation of reboiler on site,the main reasons for the shortening of operating cycle were found out, and some optimization measures were taken,thus ensuring the stable and efficient operation of ethylene plant and achieving the purposes of increasing plant capacity, reducing energy consumption and improving overall economic benefit.
