What are the reasons for the excessive total sulfur content at the outlet of the dry desulfurization tank? 1) High sulfur content at the inlet of the dry desulfurization tank, meaning that the wet desulfurization process is not effective; 2) Large fluctuations in load or an excessively high load; 3) Poor activity of the desulfurizing agent; 4) Liquid present in the upstream section, which causes the desulfurizing agent to become inactive and form clumps; 5) The end stage of the desulfurizing agent’s useful life.

(1) Low temperature in the dry catalyst bed. (2) Saturated sulfur capacity of the catalyst or catalyst deactivation. (3) Excessive load. (4) Gas quality not meeting process requirements.
1) Fluctuations in system pressure and temperature； 2) Decline in catalyst activity ； 3) Desulfurization tank saturation ； 4) Excessive production load
