Cause analysis and countermeasures of amine liquid foaming in natural gas desulfurization unit
Alcohol amine desulfurization process,especially methyldiethanolamine(MDEA)method,is commonly used in natural gas desulfurization.The problem of MDEA desulfurization solution pollution and foaming often exists in the operation process of solvent regeneration device in Yuanba purification plant.This paper analyzes the composition and source of the pollutants that cause amine foaming,analyzes the main factors affecting the foaming and foam stability of amine fluid,puts forward the measures to prevent amine foaming and the treatment measures of amine foaming,and introduces the current mature amine liquid purification technology.
