天然气净化厂MDEA脱硫溶液的发泡与预防

摘要

With the continuous growth of China's economy,the demand for natural gas continues to increase.Because the natural gas after mining has a high content of impurities,it can not be directly used for use and avoid further purification.In the current purification production,MDEA solution is used to absorb acid gas in natural gas to achieve the purpose of purification.This is mainly due to the principle that MDEA solution can react with acid gas.However,due to the certain pollution in the production process,it is easily affected by high temperature,oxidation,impurities and other factors,so that the MDEA solution appears deterioration,corrosion and foaming phenomenon,which seriously affects the quality of natural gas,so it is necessary Analyze the cause of foaming of MDEA solution in the clean production of natural gas and take effective preventive measures.%随着我国经济的不断增长,对天然气的需要量不断增加,开采过后的天然气由于杂质含量较高不能直接使用,必须对其进行进一步的净化处理.在目前的净化生产中,都要使用到MDEA溶液来吸收天然气中的酸性气体,以达到提纯的目的,这主要是利用了MDEA溶液可以和酸性气体进行反应的原理.但由于生产过程中存在着一定的污染性,很容易受到高温、氧化、杂质等因素的影响,从而使MDEA溶液出现变质、腐蚀和发泡的现象,严重影响了天然气的品质,因此有必要对天然气净化生产中MDEA溶液发泡的原因进行分析,并采取有效的预防措施.
