Abstract: A new technology in which the filter ME-101 was located outside the reactor had been applied in the S Zorb unit of a petro-chemical company, meanwhile new process had been designed, in which the adsorbent powder coming from ME-101 entered the collector D-117, and then entered the receiver D-105 through the pipe connecting the bottom of the collector D-117. The case of poor discharge appeared in the pipe between D-117 and the D-105 after the unit began to run. After the analysis on the fluidization performance of the adsorbent powder in the D-117 and the operation of the unit with different loads, it was concluded that there were two reasons which lead to the poor discharge. First, the quantity of the powder from the reactor R-101 to the collector D-117 increased with the load of the unit increasing, meanwhile the flow resistance in the pipe between the collector D-117 and the receiver D-105 increased too, which was the main reason. Second, the bad flow and fluidization performance of the adsorbent in the collector D-117 aggravated the problem. After optimizing the parameters of adsorbent transportation in the reaction and regeneration system, properly reducing the storage capacity of the reactor, and increasing the sulfur and carbon loading capacity of the adsorbent, the problem of poor discharging did not appear again under the maximum load of 96.5%.
