Abstract

A twin tower gas drying system is disclosed for filtering unpurified gas to supply purified gas to a pneumatic system. The drying system includes a separator, two coalescers, two desiccant towers and a mechanism for controlling flow of unpurified and purified gases therethrough. The separator separates moisture and other particulates from the unpurified gas. Each coalescer removes moisture remaining within the unpurified gas. A first tower removes moisture remaining within unpurified gas received from a first coalescer to provide a first stream of purified gas.
A second tower removes moisture remaining within unpurified gas received from a second coalescer to provide a second stream of purified gas. The flow controlling mechanism enables the drying system to alternately (i) extract moisture from unpurified gas passing through the first coalescer and tower to supply the pneumatic system with an output percentage of the first stream while purging moisture both previously collected in the second tower and coalescer by passing a purge percentage of the first stream through the second tower and coalescer and expelling the remoisturized gas to atmosphere via the mechanism and (ii) extract moisture from unpurified gas passing through the second coalescer and tower to supply the pneumatic system with the output percentage of the second stream while purging moisture both previously collected in the first tower and coalescer by passing the purge percentage of the second stream through the first tower and coalescer and expelling the remoisturized gas to atmosphere via the mechanism.
