Abstract:

According to the Claus catalyst Maxcel 727 developed by Porocel, this article introduced the characteristics and start-up situation of the catalyst. Relative parameters of the catalyst used in the Claus unit of Puguang Natural Gas Purification Plant during 8 years operating process were collected, and the application was analyzed. The measures for stabilizing catalyst operation were summarized, which mainly included scientific loading, stabilizing operation of desulfurization unit and air distribution optimization of Claus furnace.
