Adsorption Technology
Adsorptive oxygen installations represent a reliable system for obtaining a gaseous oxygen from the air. The equipment combines the highest technical and economic performance, simplicity and flexibility in their work.
The principle of adsorption
Separation of gas adsorption systems based on the binding of solids, known as adsorbent, the individual components of the gas mixture. This phenomenon is physically conditioned by the interaction of gas molecules and adsorbent.
Methods of preparation of gaseous oxygen from the air using adsorption technology to date, brought almost to perfection. The work of the modern oxygen adsorption is based on the fact that the absorption of the gas adsorbent is strongly dependent on temperature and partial pressure of gas.
Thus, by changing the pressure and temperature can regulate the processes of gas absorption and regeneration of adsorbent.
Technology shortcycle adsorption
The process of oxygen installations is arranged in such a way that is easy to adsorbiruemye component mixture of gas absorbed by the adsorbent, while the weak adsorbiruemye and neadsorbiruemye components pass through the installation. To date, a proliferation of three methods of cyclic adsorption separation process beznagrevnogo air: pressure (PSA), vacuum (VSA) and mixed (VPSA). For the pressure patterns derived oxygen at a pressure above atmospheric, and the stage of regeneration of adsorbent operates at atmospheric pressure. In the vacuum circuits receive oxygen at atmospheric pressure, regeneration is carried out under negative pressure. Work hybrid schemes combining the pressure change from positive to negative.
