Effect of temperature on desulfurization efficiency in fiber membrane desulfurization
Thread Content
Colleagues using fiber membrane desulfurization alcohol removal devices, have you observed any impact of temperature on the desulfurization efficiency in the alkali solution regeneration system during operation? Especially in winter, I hope everyone will pay closer attention
Reply to 1# bomber058: For the alkali solution regeneration system, 40 degrees is the most suitable temperature; either too high or too low a temperature will result in a decline in the quality of the regenerated alkali solution, thereby affecting the efficiency of desulfurization. It is recommended to use a cooler in summer and a heater in winter, especially since alkaline solutions tend to crystallize in winter. Which manufacturer’s fiber desulfurization alcohol equipment does your company use?
Fiber membrane desulfurization of alcohols – Ningbo Zhongyi has carried out many projects in this area.
Our facility is equipped with one set of heat exchangers and two sets of coolers in the alkali solution regeneration unit. The regenerated alkaline solution must be heated to at least 60 degrees before entering the oxidation tower, while it needs to be cooled to no more than 40 degrees before coming into contact with the oil in the back-extraction process. If the raw material contains hydrogen sulfide in addition to thiol, it will increase the sodium sulfide content in the alkaline solution; at low temperatures, sodium sulfide tends to crystallize and block the pipelines, preventing the heat tracing system from being turned off.
During regeneration, the temperature is around 60 degrees, but a cooler is needed to reduce the temperature to around 40 degrees
