Currently used in nitrogen, oxygen areas more carbon molecular sieve and zeolite molecular sieves. Separation of molecular sieve oxygen and nitrogen is mainly based on two gas diffusion rate of different molecular sieve surface, activated carbon and carbon molecular sieve is a molecular sieve certain characteristics of both the carbon-based adsorbent. Microporous carbon molecular sieve composition having a small pore size distribution in between 0.3nm ~ 1nm. Smaller diameter gas (oxygen) the proliferation of faster, more solid phase into the zeolite, so that the gas phase composition can be enriched nitrogen. After some time, the molecular sieve adsorption of oxygen balance, according to the carbon molecular sieve at different pressures for the absorption amount of gas different characteristics, reducing the pressure of the carbon molecular sieve adsorption of releasing oxygen, a process called regeneration. PSA typically use two towers in parallel, alternating pressure adsorption and decompression regeneration, so as to obtain a continuous stream of nitrogen.Similarly, the flow of oxygen and vice versa!
Oil and Gas Industry Special Nitrogen Making Machine
