In March 2014, the line test was carried out in hengsheng 50,000-ton ethylene glycol industrial plant in hualu, shandong. After a periodic operation assessment, the performance indexes were good. In May 2014, our company cooperated with hualu hengsheng to carry out a series of technical modifications to the device.

3 yuet shandong hengsheng glycol plant of 2015 put into operation, hydrogenation, carbonylation catalyst replacement for ningbo gold all far east petrochemical engineering technology co., LTD., products, the production load reached 100% in May, product quality reach national standard level of polyester, classy article rate is more than 95% above, at present, the product has entered the field of polyester. The production cost of constant liter per ton of ethylene glycol is 3,190.54 yuan and the total cost is 3,517 yuan.
