Effect of air temperature and desorption on oxygen generation by pressure swing adsorption

Based on the properties of miniature PSA oxygen production and a linear driving force(LDF) approximation,a mathematical model for PSA processes of a Special Miniature Oxygen Concentrator is developed in this paper.

Aiming at the existing problem on oxygen supply device in the submarine,a new method of oxygen production through water electrolysis with solid polymer(SPE) as electrolyte was proposed.

The same type of 20000 oxygen making machine should be added by analyzing the process of internal or external compression oxygen production units and comparison from many aspects such as air separation safety , equipment investment,benefits as well as variable load ability based on the present operation situation of two external compression 20000 oxygen making machines at NISCO.

Automatic load change control system in oxygen making process;

A complete comparison is made on the f ollowing of the transformation adso rp-tion oxygen making method and the dee p cooling method:process,operatio n parameter,techni-cal index,consumption of water and p ower,investment of capital constru ction,management cost,technical safety,area of land,construction requirement,operation maintenance,opera-tion staff,etc.

Pressure equalization process of miniature PSA air separation for oxygen generating;

The effects of some main factors,such as the species of molecular sieve,exchange time,pressure equalization process,ratio of height to diameter,the volume of tank on the process of small-scale pressure swing adsorption(PSA) oxygen generating are discussed experimentally.
