泸天化绿源醇业有限责任公司现有40万t/a甲醇装置和年产10万t二甲醚装置两套生产装置,其中年产40万t甲醇装置在产生过程中有大量杂醇油副产品产生。在详细分析杂醇油副产品特性并与其他公司处理方法进行对比的基础上,利用公司年产10万t二甲醚装置对其进行回收利用。该方案实施后不仅回收了杂醇油中的甲醇和乙醇,同时也解决了我公司销售杂醇油困难的问题。每年40万t/a甲醇装置副产杂醇油约1800t,可回收利用甲醇和乙醇约1170t,用于生产二甲醚约824t,按市场均价格3500元/t计算,能产生经济效益约288.4万元。 Lutianhua Lvyuan alcohol industry limited liability company existing 40 million t / a methanol plant and an annual output of 100,000 sets of dimethyl ether plant two sets of production equipment, which produces 400,000 t methanol plant in the production process has a lot of fusel oil By-product generated. Based on the detailed analysis of fusel oil by-product characteristics and comparison with other company’s treatment methods, the company recycle 100,000 tons of dimethyl ether with the company’s annual output. After the implementation of the program not only recovery of fusel oil in the methanol and ethanol, but also to solve the company’s sales of fusel oil difficult problems. Annual 400000t / a methanol plant by-product fusel oil 1800t, recyclable methanol and ethanol about 1170t, for the production of dimethyl ether about 824t, according to the market price of 3500 yuan / t calculation, can produce economic benefits of about 288.4 Million.
