Industry insiders of membrane separation gas industry think that the technological development of membrane separation gas industry in our country mainly includes the following technical points:
(1) for membrane technology which has been applied in industrialization in our country, such as micro-filtration, superfiltration, reverse permeability and gas separation membrane, we should strengthen the development efforts, improve product quality and form scale benefits. Take solving membrane materials and membrane manufacturing technology as the core, break through the preparation technology of composite reverse permeability membrane, and make the products reach the international level; carry out Industry Planning and scientific and technological development, and improve the technical level of domestic superfiltration membrane, maintain a relatively high market share. On the basis of successful industrial application of membrane hydrogen extraction, membrane oxygen enrichment, membrane nitrogen enrichment and other technologies, it has developed into the aspects of natural gas purification, separation of water vapor, carbon dioxide and organic vapor, and expand the application field from the current recycling of waste resources to the fields such as environmental protection, industrial gas production and gas purification; the gas membrane separation technology is developed from the existing gas source which processes high pressure, high concentration and simple components to the direction of low pressure, micro, high temperature and complex components.
(2) for membrane technology which has been industrialized applied abroad and is still in the stage of pilot study in our country, such as nanofiltration membrane, the preparation technology of composite nanofiltration membrane should be broken through; accelerate the construction of the demonstration project of inorganic separation membrane and technology center, promote the popularization and application of technology, and realize the industrial production of inorganic superfiltration membrane; take percolation vaporization membrane as the research emphasis of membrane material, on the basis of completing the technology of alcohol/water separation, actively expand to the study of membrane materials and membrane process of organic matter/organic matter separation.
(3) the research and development of the projects which have not been started abroad for a long time, such as membrane catalytic, membrane reactor, membrane distillation, membrane extraction, membrane and biotechnology and other new membrane processes and integrated membrane process, hybrid membrane process research, all need to be divided and explored, build high-quality scientific research team, seek new growth point of our country's technology, or independent technology with innovation level.
