How to control the temperature of desulfurization liquid in winter
Thread Content
For the regeneration of high towers and the PDS desulfurization process using soda ash, the optimal temperature for the desulfurization solution is 35–38 degrees Celsius. However, it is difficult to maintain this temperature range in winter; this not only leads to unstable desulfurization but also reduces the solubility of the salts present in the desulfurization solution, resulting in salt accumulation within the system and an increase in system resistance. This further hinders the efficiency of desulfurization. How can this problem be solved?
The idea is to raise the temperature of the desulfurization liquid to 35-38 degrees.
If, after a thorough analysis, you determine that the issue is related to temperature, then technical modifications can be carried out, or the cooling temperature of the regenerated caustic soda can be reduced. Generally, the feed temperature for gasoline in fixed-bed reactors is between 30 and 32 degrees; nowadays, it is rarely used with naphtha hydrogenation. Liquefied gas generally does not cool down to very low temperatures; if the temperature in the stabilizer becomes too low, it means that the energy consumption of the entire stabilization system is high
