Hydrogen recovery and purification
Thread Content
I have a question for everyone: After the hydrogenation reaction in our company, a large excess of hydrogen is produced, and we want to recycle this hydrogen. However, the hydrogen contains by-products such as trifluoroethylene and trichloroethylene, and these by-products can have a significant impact on the stability and safety of the equipment during recycling; therefore, they need to be removed. We are considering using membranes for this purpose, but the cost is high. So I would like to ask if there are any other better separation methods available. (Trifluoroethylene has a boiling point of -61 degrees, and trichlorofluoroethylene has a boiling point of -28.36 degrees; both are flammable and explosive substances.)
What is your operating pressure?
Without a feasibility analysis, discussing it
You can find refineries that use the same process, do some research, and then make a decision
For temperature-dependent adsorption, alumina can be considered as the adsorbent
The poster can send me the detailed parameters at scly8844@163.com. Flow rate, temperature, detailed composition. Consider whether to use temperature swing adsorption (TSA), pressure swing adsorption, or a combination of both. Our company can handle such difficult and complex gases. Similar production facilities exist in the fields of pesticides, biochemistry, chlor-alkali, and polysilicon.
It is recommended to go and inspect similar installations, and combine them with your own processes and those of the design institute. . .
