Abstract
MDEA solution,as a key decarbonization medium in the production process of synthetic ammonia,although it has excellent decarbon-ization performance and chemical stability,is easily contaminated by pollutants carried by feed gas,corrosion products of equipment materials,ox-idation products,foreign impurities,and by-products of regeneration process in actual operation,resulting in reduced decarbonization efficien-cy,increased operating costs,and damaged equipment life.This article provides an in-depth analysis of the sources of pollutants in MDEA solu-tions,and compares and analyzes two typical purification processes,ion exchange resin purification and evaporation purification,clarifying their respective advantages and disadvantages,providing practical reference for the purification of decarbonization solutions in synthetic ammonia.关键词
