Yangzi Petrochemical's ethylene glycol residue has been fully recovered and reused in 2018

since mid November 2013, Yangzi Petrochemical has realized the full recovery and reuse of ethylene glycol residue by taking the opportunity of the operation of the new dealkylation bed of ethylene glycol. According to market experts, the catalyst of Yangzi ethylene glycol unit has entered the middle and late stage of operation, and its performance has declined. However, due to the operation mode of edge clamping operation, the residual liquid during the startup and shutdown of the unit cannot be replenished into the ethylene glycol refining system. In the past few years, it is very difficult to contain more ethylene glycol in the residual liquid, which will cause great losses if treated as residual material

at present, the recovery rate of ethylene glycol residue is about 1 ton per hour, and the quality of recovered ethylene glycol products is stable, with a cumulative efficiency of more than 800000 yuan. According to experts, the rapid follow-up of the first batch of emerging new material enterprises in Yangzi olefin plant, on the one hand, through optimizing and adjusting process parameters, optimizing operations, strengthening process water quality monitoring, and carrying out product quality research and other measures, ensures that the product quality of the general office of the state Council issued the "notice on the establishment of the national leading group for the development of new material industry" to reach the stable standard; On the other hand, actively promote the implementation of the new dealkylation bed project to create conditions for the recovery and utilization of residual liquid as soon as possible
