摘要
采用Amine Sweetening-SRK和Amine Sweetening-PR专用物性模型对净化厂净化装置脱硫单元进行了模拟计算,分析了MDEA循环量、浓度及水蒸汽加热介质等可调参数对净化过程的影响。针对湿净化气温度偏高的现象,提出增加1个气/气换热器的建议。从降低能耗、节约生产成本的方面,提出暂停使用大流量泵以及利用净化厂所处的地理位置和自然气候,水冷器只在夏季使用等建议。
The Amine Sweetening-SRK and Amine Sweetening-PR physical model are used to simulate the desulfurization unit in purification devices in the purification plant. The influence of the adjustable parameters such as the amount of MDEA cycle,the concentration and the steam heating medium on the purification process is analyzed. In view of the phenomenon of high temperature of the wet gas,the proposal of adding one gas/gas heat exchanger is proposed.From the reduction of energy consumption and saving production costs,some suggestions,including the suspension of the use of large flow pumps,the use of the geographical location and natural climate of the purification plants,and the use of water coolers only in the summer,are put forward.
