摘要

这项工作致力于从基于单乙醇胺（MEA）的模型吸收剂中去除溶解氧，以防止其在从二氧化碳中吸收净化烟气过程中的氧化降解。开发了基于多孔陶瓷和聚合物载体的复合膜，该复合膜具有聚[1-（三甲基硅烷基）-1-丙炔或其与聚乙烯基三甲基硅烷的共混物的薄选择性层，并在此基础上创建了气液膜接触器。结果表明，在真空模式下使用这些承包商可以从模型吸附剂中去除高达60%的溶解氧。

Deoxygenation of CO2 Absorbent Based on Monoethanolamine in Gas–Liquid Membrane Contactors Using Composite Membranes

This work is devoted to the removal of dissolved oxygen from a model absorbent based on monoethanolamine (MEA) to prevent its oxidative degradation during the absorption purification of flue gases from carbon dioxide. Composite membranes based on porous ceramic and polymeric supports with a thin selective layer of poly[1-(trimethylsilyl)-1-propyne] or its blend with polyvinyltrimethylsilane are developed, and gas-liquid membrane contactors are created on their basis. It is shown that the use of these contractors in the vacuum mode allows the removal of up to 60% of dissolved oxygen from the model sorbent.

期刊介绍： The journal Membranes and Membrane Technologies publishes original research articles and reviews devoted to scientific research and technological advancements in the field of membranes and membrane technologies, including the following main topics:novel membrane materials and creation of highly efficient polymeric and inorganic membranes;hybrid membranes, nanocomposites, and nanostructured membranes;aqueous and nonaqueous filtration processes (micro-, ultra-, and nanofiltration; reverse osmosis);gas separation;electromembrane processes and fuel cells;membrane pervaporation and membrane distillation;membrane catalysis and membrane reactors;water desalination and wastewater treatment;hybrid membrane processes;membrane sensors;membrane extraction and membrane emulsification;mathematical simulation of porous structures and membrane separation processes;membrane characterization;membrane technologies in industry (energy, mineral extraction, pharmaceutics and medicine, chemistry and petroleum chemistry, food industry, and others);membranes and protection of environment (“green chemistry”).The journal has been published in Russian already for several years, English translations of the content used to be integrated in the journal Petroleum Chemistry. This journal is a split off with additional topics.
