There is a large amount of HCL gas in production, 40-50M3/H, which contains easily crystallized components. Please tell me how to absorb it? :funk: :funk: :funk:
Use desalted water to absorb it and make hydrochloric acid for sale. The current price of hydrochloric acid is not low!
The easy-to-crystallize components can be separated through crystallization, and the tail gas HCL gas is absorbed through the falling film to make hydrochloric acid for sale. Falling film absorbers are produced by many manufacturers in Nantong, Yangzhou and other areas.
Similar views. Use graphite products for treatment and absorption.
The problem is how to remove the crystalline component. This component is easy to crystallize when exposed to water. It is troublesome to crystallize the equipment. What should I do?
If you don't have much equipment, you can use ammonia to absorb it and sell it as fertilizer. A vacuum pump is enough.
Your suggestion is very good. It is better to absorb it under slight negative pressure. This post was last edited by swdy67 on 2008-2-4 16:10 ]
Absorbed with alkaline ammonia water, generally considered as fertilizer
The HCL gas in the chemical and pesticide industry that I have been exposed to uses a three-stage falling film method to absorb and make hydrochloric acid, which not only treats the process waste gas, but also recovers resources, and the higher the concentration, the better it is absorbed. Only when the HCL gas in the process tail gas still cannot meet the "Comprehensive Emission Standards for Air Pollutants" after the above treatment, caustic soda will be used to absorb it so that the tail gas can be discharged up to the standard. Simply using caustic soda for absorption is not economical enough!
Falling film absorption can be used, with the product acid concentration reaching 31% and zero tail gas emissions. The main process is as follows : Falling film absorption (graphite equipment) - tail gas absorption tower (packed tower countercurrent) - water jet absorption - tail gas venting
Using the three-stage falling film method for absorption, the absorption rate of HCl can reach more than 99.8%. The absorbed HCL can be made into industrial hydrochloric acid of various concentrations for use, eliminating pollution and increasing income. Many factories use it.
It’s not difficult in terms of craftsmanship, just put some effort into anti-corrosion.
The falling film absorber can absorb HCl gas and turn it into hydrochloric acid, turning waste into treasure and saving environmental protection costs. There are several companies in Taicang, Suzhou that provide such products.
