色谱法提纯鱼油中EPA/DHA生产过程甲醇回收工艺对比Comparison of methanol recovery processes in the production of EPA/DHA purified from fish oil by chromatography
旨在为色谱法从鱼油中进一步分离纯化DHA和EPA生产企业甲醇废液回收工艺方案选择提供参考,介绍了普通单塔精馏、双效精馏、单塔热泵精馏和双塔热泵精馏4种甲醇回收工艺流程和主要参数,并以40 t/h甲醇废液为例,利用Aspen Plus软件对4种甲醇回收工艺路线的运行能耗做了模拟计算,对其成本进行了对比分析。结果表明:普通单塔精馏、双效精馏、双塔热泵精馏和单塔热泵精馏的冷却能耗和加热能耗依次降低;对比压缩机电耗在内的综合能耗(折合标煤),普通单塔精馏最高,双塔热泵精馏、单塔热泵精馏和双效精馏综合能耗分别是普通单塔精馏的34.2%、35.3%和56.5%;普通单塔精馏、双效精馏、单塔热泵精馏和双塔热...
