How to effectively recover formic acid that evaporates during the production process
Thread Content
Help, help, help! ! ! During the production process, formic acid needs to be heated to 90 degrees, which results in significant volatilization. I am considering installing a condenser above the reaction apparatus to capture this vaporized formic acid. I wonder if this is feasible, or if there are better ways to reduce the volatilization of formic acid or to effectively recover the vaporized formic acid. Thank you!
Direct low-temperature condensation, or recovery through water absorption and desorption.
What is your production pressure? Is it at atmospheric pressure? The boiling point of formic acid is 100.8 degrees.
Condensation recovery is possible; the issue is how to achieve material balance in the reaction system.
{:3_54:} The amount of material and the temperature can only be adjusted based on the discharge specifications; you can use a secondary condenser, primary circulating water, and secondary chilled water. With stricter environmental regulations nowadays, you’ll definitely need to add an absorption unit as well
