美国AMT公司(AMT International Inc.)和韩国LG化学公司合作,采用最新萃取精馏工艺,对LG化学位于韩国丽水的一套芳烃装置成功进行了改造。该装置原来采用传统的液液萃取工艺,溶剂为环丁砜。本次改造利用了原有芳烃装置绝大部分已有的设备,而且继续延用原来的环丁砜溶剂。改造后的萃取精馏芳烃装置于2013年4月开车,和原来的液液萃取工艺相比,在芳烃产品的纯度和收率都达到设计要求的情况下,萃
AMT International Inc. and South Korea’s LG Chem, in collaboration with South Korea’s LG Chem, have successfully transformed LG Chem’s aromatics plant in Lishui, South Korea, using the latest extractive distillation process. The device uses the traditional liquid-liquid extraction process, the solvent is sulfolane. The transformation of the original use of existing aromatic plant most of the existing equipment, and continue to use the original sulfolane solvent. The upgraded extractive distillation aromatics unit was started in April 2013. Compared with the original liquid-liquid extraction process, when the purity and yield of the aromatic hydrocarbon products meet the design requirements, the extraction
