Abstract: To address the problems of low processing load of S Zorb gasoline refining unit and agglomeration of adsorbent in the regenerator, combined with the actual operation of the unit, nitrogen heat removal is adopted instead. When increasing the processing capacity or processing high sulfur gasoline, the regenerator heat removal is limited. According to the existing problems, the reasons are analyzed. The following solutions are put forward: stable control the processing load; reasonably control the circulation speed of the adsorbent; add catalyst cooler in regenerator on the outer wall, reasonable control of adsorbent activity and circulation speed; ensuring normal flow at each loose point. By adopting the above scheme, the problem of adsorbent agglomeration is alleviated.
