摘要
兰州炼油化工总厂Ｎ－甲基吡咯烷酮溶剂精制装置萃取塔填料由乱堆填料改为以规整填料为主的复合填料，填料层数由８层增加到１０层，填料总高度由１２．５ｍ增加到１７．０ｍ，使理论段数和通量提高。改后装置加工能力由上年度１８０．６ｋｔ／ａ提高到２１８．７ｋｔ／ａ，能耗由１５３０．２７ＭＪ／ｔ下降到１３２７．２２ＭＪ／ｔ，溶剂消耗由０．７９ｋｇ／ｔ下降到０．５２ｋｇ／ｔ，经济效益为６８２．７５万元／ａ，投资回收期仅０．０９７年。
The extraction tower of the solvent refining unit at Lanzhou Petroleum Processing and Chemical Complex was revamped. The jumbled packing was replaced by complex packing which mainly consisted of regular packing. The packing layers increased from 8 to 10, and the overall packing height increased from 12.5 m to 17.0 m, thus the theoretical stages and flux were increased. The throughput was increased from 180.6 kt/a to 218.7 t/a; the energy consumption was decreased from 1 530.27 MJ/t to 1 327.22 MJ/t; and the solvent consumption also reduced from 0.79 kg/t to 0.52 kg/t after revamping.
