碳酸二甲酯生产中液体二氧化碳冷量利用的研究

摘要

研究了碳酸二甲酯装置生产过程中液体二氧化碳冷量利用的问题.通过合理利用液体二氧化碳的冷量,起到了既能替代冷水机组制冷,又能降低装置蒸汽消耗量的作用.装置经过二氧化碳冷量利用改造后,经济效益大大提高.%The cold energy utilization of liquefied carbondioxide was studied. Through utilizing cold utilization of liquefied carbondioxide, refrigeration with chillers was replaced, the steam consumption was also reduced. Economic efficiency of the device was greatly increased by utilizing cold energy of liquefied carbondioxide.
