2015年6月1日 · The effects of process parameters on foaming behavior of MEA, MDEA, and 2-Amino-2-Methyl-Propanol (AMP) and their mixtures were systematically investigated by Thitakamol and Veawab (2008), it was concluded that the degradation products or corrosion inhibitors affect the foaming behavior of the amine solution.

2022年8月1日 · Obtained the best performance of silicon antifoam at 0.1 wt% for MDEA+IPAE mixture. This paper provides an experimental study on the foam behavior of aqueous solutions of MDEA and IPAE by the modified standard ASTM D892.

mdea (n-甲基二乙醇胺)溶液，广泛应用于天然气、油田气、煤气的净化工艺，在其使用过程中， 经常会出现溶液发泡现象，影响整个装置的平稳运行。 造成净化气质量不达标[1]、大量的溶液质量损失，

2014年3月1日 · Thitakamol and Veawab (Thitakamol and Veawab, 2008) systematically investigated the effects of process parameters on foaming behavior of MEA, MDEA, and 2-Amino-2-Methyl-Propanol (AMP) and their mixtures. They identified and used ranges of solution volume and gas flow rates for measuring the foaminess coefficient.

MDEA solution is widely used in the purification process of natural gas, oil field gas and coal gas. Amine liquid is an easy foaming system. The foaming of amine liquid will cause problems, such as flooding of the desulfurization device, solvent loss, production reduction, and unqualified purified gas, and even cause the device to shut down ...

Foaming in amine plants increases operating costs and reduces treating efficiency. When foam-ing becomes severe, amine is often carried over into downstream treating equipment. It is com-monly held that liquid hydrocarbons and iron sulfide cause foaming.

industrial lean Methyldiethanolamine (MDEA) used as solvents at different temperatures. This study aimed at investigating the effect of HydroCarbon Based (HCB) and fatty acid based corrosion inhibitor having chemical name Bis(2-Hydroxyethyl)Cocoalkylamine (BHCL) on the foaming tendency of industrial real lean MDEA solutions.

2015年2月5日 · 摘要：大型天然气处理装置普遍采用醇胺法工艺，目前主要使用MDEA及其配方溶剂对酸性天然气进行净化处理。 由于MDEA溶液本身抗污染能力存在不足，加之醇胺溶液的降解、变质、腐蚀等因素，溶液发泡的情况时有发生，影响了装置的平稳操作，导致产品气不合格，造成溶剂大量损失，严重时甚至引起装置停车。 从发泡机理入手，通过开展大量实验，系统地评价了MDEA溶液系统中存在的多种杂质对脱硫溶液发泡的影响，对实际生产可起到一定的借鉴作用 …

2018年5月9日 · Foaming is one of the major operating problems in natural gas sweetening alkanolamine plants. The lean methyldiethanolamine (MDEA) samples collected at different times from GASCO (Habshan, Abu Dhabi) sites were analyzed analytically and laboratory foaming studies were carried out to understand the root cause of foaming.

increase the pure MDEA concentration will decrease the foaminess. Similarly results also indicated that by increase the solution temperature will decrease the foam form.
