Abstract

A modular pressure swing tonnage adsorption (PSA) apparatus for separating mixtures of gases into component parts comprises a plurality of pre-fabricated modules adapted for on-site assembly. The modular apparatus includes a first module including at least one gas adsorption apparatus for effecting the gas separation, a second module including a surge tank for collecting one component gas separated out of the gas mixture by the first module, a third module including apparatus for delivering the gas mixture to the first module and for conducting waste gas away from the first module, a fourth module including apparatus for transfering the one component gas away from the first module to the second module, and for directing gas to the first module for purging the first module, and apparatus for pneumatically and electrically, mechanically interconnecting the first, second, third and fourth apparatus, so that the modules may be delivered as individual modules to a site for PSA use, and assembled on-site by mechanically, pneumatically and electrically interconnecting the components, to thereby produce a relatively large such unit adapted to produce relatively large quantities of the one component of gas.
