The temperature issue of the desulfurization solution in chestnut gum desulfurization

The gas temperature is around 20 degrees Celsius; I plan to add a cooler. I still don’t know the reason for the increase in temperature

Reasons for the increase in gas pressure: 1. High consumption of steam used for gas production; 2. Low water volume in the wash towers at the inlet and outlet of the gas holder; 3. High temperature at the inlet of the desulfurization fan; 4. Clogged nozzles due to low water volume in the wash tower at the inlet of the desulfurization fan; 5. Clogged nozzles due to low water volume in the wash tower at the outlet of the fan; 6. Large rotor clearance in the Roots fan, resulting in circulation; 7. Excessive backflow or internal leakage at the bypass valve connecting the outlet and inlet of the Roots fan

None of what you said is correct; the temperature of the gas produced by the transformation is only around 20. Before driving, the temperature of the desulfurization liquid was also in the low 20s degrees Celsius; the syngas produced was fed directly into the desulfurization tower. However, the temperature of the desulfurization liquid continued to rise, eventually reaching over 60 degrees Celsius.

Isn’t yours a fixed-bed batch gas production system? Is it semi-water gas desulfurization or shift gas desulfurization? It wasn’t made clear; I thought it was half-water gas desulfurization.

After the transformation, is there an organic sulfur conversion furnace? If not, then steam enters the lean liquid tank.

The desulfurization liquid circulation is done using a lean liquid pump, right? Should I use one or two? I suspect that the circulation rate of the desulfurization fluid does not match the volume of the shifted gas; it might be possible to shut down one of the lean fluid pumps in order to reduce the circulation rate of the desulfurization fluid and see what happens

Alkaline solutions absorb hydrogen sulfide gas; there is already a temperature rise of 3–5 degrees due to the reaction heat. In other seasons, during the circulation of the desulfurization solution and in the regeneration tank, heat is lost due to the entry of large amounts of air, but this allows the heat balance to be maintained so that the temperature does not become too high. However, when the solution is circulating in summer, first, the temperature of the equipment pipes is high; second, due to the high ambient temperature, the temperature of the air drawn into the solution by the ejector is also high, as a result of which no cooling effect is achieved. If this portion of the reaction heat cannot be absorbed, or only very little of it can be absorbed, it will cause the temperature to rise increasingly. However, it won’t stay that high either; over 60 degrees is already the limit. When the temperature of the solution is too high, even air at 40 degrees drawn in by self-priming can help to lower the temperature. Once equilibrium is reached, it will no longer rise. Given the frequent occurrence of extreme weather conditions these days, it is quite necessary to include a solution heat exchanger in the design. Cooling in summer and heating in winter is beneficial for the management of desulfurization operations. By the way, could someone change my name? I’m no longer with Dongshi; it should be Zhang Tong from Jiangsu Minglang. Thank you.
