摘要
中国石油化工股份有限公司巴陵分公司烯烃厂ARGG装置在实际运行中暴露出能耗高、蒸汽难平衡等问题,通过运用大系统用能综合分析方法,分析装置用能现状,找到了换热流程的“瓶颈”,并运用窄点设计方法,确定最优的热量传递网络,网络换热终温由260℃提高到272.5℃;结合装置扩能改造,考虑装置原有流程布置,充分利用装置原有设备,确定最终的换热流程;两年的实际运行表明,本次换热网络优化取得了显著的经济效益,原油换热终温由改造前不到285℃提高到305℃,节能效果显著。
High energy consumption and unbalanced steam were exposed in the operation of olefin plant in Baling Petrochemical Co. , Ltd. The 'bottleneck' in heat exchange train has been found out by analyzing the energy usage of unit by comprehensive analysis method for large system, and the optimal heat exchange network determined by pinch point design method. The terminal temperature of heat exchange network has been . increased from 2601 to 272. 5 ℃ and the terminal heat exchange flow scheme was decided in the revamping of unit with a sufficient consideration of existing flow scheme and equipment. Two-year operation data shows that excellent economical benefits have been gained by the optimization of heat exchange network. Terminal temperature of crude heat exchange has been increased from 285℃ to 305℃. Energy conservation effect is evident.
