Successful Application of Leader’s New Type SLC-S Slurry Catalyst at 300 KTPA PE Plant of Inner Mongolia ChinaCoal Mengda New En
The 300 KTPA polyethylene plant of Inner Mongolia ChinaCoal Mengda New Energy & Chemical Co., Ltd. adopted American Univation’s licensed technology of gas phase polyethylene. To lower the catalyst procurement cost and shorten the procurement lead time, ChinaCoal Mengda started to try out domestic new type SLC-S slurry catalyst developed by Shanghai Leader Catalyst Co., Ltd. on November 19, 2016, on which the first drum was injected. By December 11, 2016, the catalyst concentration had reached 100%. The plant was stably operated and had no production upset in the course of trial. In comparison with application of the imported catalyst, there were no obvious differences in terms of the reactor temperature, static electricity and agglomerates and the trial could meet the production requirements. The product performance indices were equivalent to those of the imported catalyst and the product premium grade rate was 100%. After wrap-up of the trial, leaders of both companies unanimously agreed that the new type SLC-S slurry catalyst of Shanghai Leader Catalyst Co., Ltd. could meet normal production demand of the plant and the trial was successful.
