Abstract
Membrane Gas Separation Plants based on hollow fibers are actively manufactured and introduced into production abroad. The annual sales of Generon (USA), the world's leading company in delivery of the nitrogen plants, is about 400 units of equipment of capacity to 4000 m3/h. Essentially no hollow fiber for gas separation is produced Russia. At several institutes of the Russian Academy of Sciences performed are research works only. In 2014 JSC Cryogenmash decided to develop an experimental-industrial technique for gas-separation hollow fibers fabrication, as well as to launch the membrane modules manufacturing based on gas-separation hollow fibers for a number of industrial processes: recovery of nitrogen from air, extraction of helium from natural gas and concentration of hydrogen from ammonia production gases. The experimental technology was developed for hollow fibers production of fiber capacity of about 10m/min. Produced are the lots of fibers for nitrogen-from-air concentration. The highest selectivity coefficient reached for O2/N2 pair is within the range of 4,9–5,1, that approaches the characteristics of UBE (Japan) membrane nitrogen modules. Active continuation of works on development of domestic experimental industrial technology is planned for stable manufacture of hollow gas-separation fibers and modules on their basis.
