Methyldiethanolamine is a chemical substance that is miscible with water and alcohol and slightly soluble in ether. Widely used in oil field gas and coal gas desulfurization purification emulsifier and acid gas absorbent, acid-base control agent, polyurethane foam catalyst.
What is the use of nitrogen blanketing in the methyldiethanolamine tank?
Insulate from air to avoid oxidative degradation.
1. Prevent the amine liquid from contacting oxygen, which will cause the amine liquid to oxidize, generate thermally stable salt, increase the loss of amine liquid, reduce the desulfurization effect, and aggravate corrosion.
2. Prevent the hydrogen sulfide in the barren liquid from volatilizing and causing peculiar smell.
