| Abstract: | The propylene dearsenifying process in 150 kt/a polypropylene plant in Jinxi Petrochemical Company is presented. Combining with the practical application process of KTA-2 arsenic removal agent and the production data, the industrial application of the KTA-2 arsenic removal agent in the process of propylene purification is summarized. The results of industry application indicate that the KTA-2 arsenic removal agent has superior activity, the mass fraction of arsenic compounds in refined propylene is lower than 20× 10^-9, the elimination efficiency of As is higher than 99. 1% which meets the requirement of arsenic content by the high efficiency catalyst for refining propylene; the KTA-2 arsenic removal agent has superior As capacity and the penetrate As capacity can reach 10%. |
