PRESSURE CYCLING CONTROL FOR FLUID SEPARATOR MECHANISM

摘要

PRESSURE CYCLING CONTROL FOR FLUID SEPARATOR MECHANISM A control system for sequentially connecting a pressurized fluid mixture to first and second beds of adsorption material to separate a component from the fluid mixture and produce a product effluent. A first valve mechanism allows the fluid mixture to flow to the first bed and a portion of the product effluent to purge the component from the second bed In a first portion of a mode of operation. A second valve mechanism allows the fluid mixture to flow to the second bed and a portion of the product effluent to purge the component from the first bed in a second portion of the mode of operation. A first sensor develops a first signal corresponding to the fluid pressure of the product effluent In the first bed and a second sensor develops a second signal corresponding to the fluid pressure of the product effluent to the second bed. A pneumatic logic sequencer connected to the first and second sensors responds to the first and second signals to sequentially operate the first and second valves and establish a cycle of operation.
