How to determine precise desulfurization
Thread Content
Is the desulfurizer deactivated and needs to be replaced?
1. The desulfurizer becomes saturated with absorption, causing a change in color; 2. The desulfurizer clumps together; 3. The absorption efficiency decreases, resulting in excessive hydrogen sulfide levels at the outlet.
1. First, consider the service life of the desulfurization agent. 2. Comprehensive analysis based on the sulfur content at the inlet and the sulfur content at the outlet. 3. Is there still room for adjustment in the entire system? 4. If the desulfurization agent is loaded in sections, samples can be taken from between these sections to analyze the desulfurization efficiency of each section, so as to determine which section has a less severe issue; there is no need to replace the entire agent, which would result in waste.
By sampling each layer and analyzing its hydrogen sulfide content, it can be determined which layer has reached sulfur capacity saturation； The usage time can also be calculated based on the hydrogen sulfide content in the imported material and its sulfur capacity
The iron-molybdenum, cobalt-molybdenum, and zinc oxide desulfurizers produced by that manufacturer are of high quality! Thank you all!
The zinc oxide desulfurization agents produced by companies such as Shanxi Keling Purification Company, Hubei Chemical Research Institute, and Changge Yuxin have good performance
The sulfur capacity to be used should be determined based on the conditions of each plant; if it is calculated that the desulfurizer after regeneration cannot achieve the required desulfurization level at the outlet, it needs to be replaced
