Trans-membrane phase separation process was first applied to gas separation, such as: natural gas purification, the essence of which is the use of membranes to completely separate the gas phase, the liquid phase (absorbing liquid), so as to avoid the traditional process of bubbling, liquid flooding, foam entrainment and other problems, the material basis of this process is a suitable hydrophobic membrane, PTFE material hydrophobic, corrosion-resistant, high-strength, low surface energy is the ideal material for the membrane system, but it is also the existence of a membrane, difficult, pore size is not easy to adjust and other difficulties, after more than 10 years of research and development of our company has a complete set of independent intellectual property rights PTFE hollow fiber membrane production process. After more than ten years of research and development, our company has a complete set of PTFE hollow fiber membrane production process with independent intellectual property rights, which has won the first prize of Science and Technology of China Membrane Industry Association, the first prize of Dalian Municipal Technological Invention, the first prize of Dalian Municipal Patent Award, the IChemE Malaysia Awards for Oil and Gas Award, the IChemE Global Awards, the IChemE Global Awards, the IChemE International Awards, the IChemE International Awards and the IChemE International Awards for Oil and Gas. Award, IChemE Malaysia Awards for Oil and Gas, IChemE Global Awards with Highly Commended Research Project Award and a series of other important domestic and international awards.
