RECENT PROGRESS OF OXYGEN/NITROGEN SEPARATION …

Pressure swing adsorption (PSA) (Fig. 2) is a non-cryogenics air separation process which is commonly used in the commercial practice. This process involves the adsorption of the gas by adsorbent such as zeolite and silica in a high pressure gas column. In the PSA process, the air is drawn from the ambient and compressed into high pressure gas ...

Expander Process - an overview | ScienceDirect Topics

In most instances, the gas flow into the separator comes directly from the wellhead, because the gas-oil separation process is not needed. The gas stream enters the processing plant at high pressure (600 psi or greater) through an inlet slug catcher where free water is removed from the gas, after which it is directed to a condensate separator.

PowerPoint Presentation

Cryogenic air separation takes advantage of the differing boiling points of its components as shown in Table 1. In order to start the separation process, a large quantity of the incoming air needs to be liquefied. This is accomplished by cooling the air by decreasing its temperature and manipulating the pressure until condensation begins.

Reflux - Wikipedia

The separation can be enhanced with the addition of more trays (to a practical limitation of heat, flow, etc.). The process continues until all the most volatile components in the liquid feed boil out of the mixture. This point can be recognized by the rise in temperature shown on the thermometer.
