As medical oxygen becomes a luxury, scientists are working on a cheaper way to produce it. By studying different materials for storing and separating the gas, molecular is fulfilling the potential of its solution.
YAMTOP oxygen enrichment molecular sieve series are special used in PSA/VPSA system. They have good N2/O2 selectivity, good crush strength and low loss on attrition, which is cost-effective for concentrating oxygen from air. They are widely used in industrial/Medical oxygen concentrator in ozone production filed, Aquaculture field for fish farming, waste water treatment field, medical oxygen market. etc. Their concentating purity up to 93%+-3%, having good reputation in market.
Oxygen is obtained primarily from liquefied air, where technicians turn the air people breathe into a liquid, using a combination of processes to cool the gases until they condense. Once they manage to liquefy the mixture, they use distillation - the same process used to make whiskey and gin - to separate the air into its different components, which include oxygen.
A way to make oxygen is to use a concentrator, a device that selectively removes nitrogen - which makes up 78 percent of our atmospher. Currently, there are research teams studying new materials for storing and separating gases, and two main types of materials are being developed - zeolites (crystals of silicon, aluminum and oxygen) and metal-organic skeletons. Both are highly porous materials. You can think of them as miniature, molecular-sized sponges. These porous materials absorb more fluid than you might intuitively imagine. Small amounts of zeolite and metal-organic skeletons can store large amounts of fluids, usually gases, and they have been used for gas storage, purification, carbon capture, and water harvesting.
