Extraction of desulfurization by-products
Thread Content
Recently, the H2S content in the gas downstream of the tower in our plant’s desulfurization system has consistently been above 200, and at times even exceeded 500. It is suspected that the high level of by-products in the desulfurization solution is causing poor regeneration. Previously, we would transport some of the desulfurization liquid to the coal yard for spraying, but later we found that this caused corrosion in the coal transportation system, so we stopped doing that. As a result, the desulfurization liquid was not replaced for a long time. I heard that there is a device for extracting by-products; how effective is it, according to everyone?

A company from Tai’an contacted me a couple of days ago; their phone number is 13171497152, so you can get in touch with them for more information
The content of by-products has a significant impact on the desulfurization efficiency of the desulfurization solution. The by-product extraction equipment plays a very positive role in reducing the level of by-products in the system fluid, but this does not mean that no liquid will need to be discharged outside the system. . . The increase in hydrogen sulfide content is influenced by various factors; it is recommended to conduct analysis from aspects such as sulfur content in the coal blend, hydrogen sulfide concentration before the tower, content of by-products salts, and suspended sulfur in the clear liquid
Reply to 3# lwtaigang: May I ask which factory you are from? How is the performance of your product? Is the product effective?
It’s probably not entirely a problem with by-products; it’s recommended to have it tested. It could be fluctuations caused by rising temperatures, or it may be due to unstable quality of the desulfurization agent.
May I ask which factory you are from, and how is the performance? Is the product effective?
The production of by-product salts has been facing difficulties; the quality of the products does not meet the standards. It’s impossible to make a profit from environmental protection projects – their purpose is merely to reduce pollution
There are many desulfurization waste liquid treatment plants these days. Just find one with better performance. The by-products of extraction are mainly thiocyanate and thio compounds; the higher the purity, the more expensive they are, and they represent the most important chemical raw materials. A price below 96% is considered very low. Now, most coking plants have installed systems for treating desulfurization waste liquid and extracting by-products.
