Claim 1
Independent Claim
196 words
IN A GAS DEHYDRATION SYSTEM WHEREIN A MAIN GAS STREAM IS DEHYDRATED BY PASSING IT THROUGH A FIRST BED PF DEHYDRATING MATERIAL WHILE A SECOND BED OF SUCH MATERIAL IS BEING REGENERATED, THE IMPROVED PROCESS FOR REGENERATION COMPRISING THE STEPS OF CONTINUOUSLY WITHDRAWING A PORTION OF THE DEHYDRATED GAS EFFLUENT FROM THE FIRST BED, FLOWING SAID PORTION TO A HEATING ZONE AND THEREIN HEATING SUCH PORTION TO A TEMPERATURE SUFFICIENTLY HIGH TO REGENERATE SAID SECOND BEDM FLOWING THE THUS HEATED GAS PORTION DOWNWARDLY THROUGH THE SECOND BED DURING AN ENTIRE HEATING PERIOD UDNTIL THE LATTER IS HEATING TO A DESIRED EXTENT, THEN IN A COOLING STEP CEASING HEATING OF SAID GAS PORTION IN SAID HEATING ZONE WHILE CONTINUING TO WITHDRAW SAID GAS PORTION FROM THE FIRST BED EFFLUENT AND FLOWING IT DOWNWARDLY THROUGH SAID SECOND BED TO COOL THE SAME, AND CONTINUOUSLY REMOVING, DURING THE HEATING AND COOLING STEPS, ALL OF SAID GAS PORTION FROM THE SECOND BED AFTER IT HAS FLOWED ONCE THERETHROUGH WHILE PREVENTING FLOW OF SUCH GAS PORTION SO REMOVED AGAIN THROUGH THE SECOND BED WHILE IT HAS A MOISTURE CONTENT GREATER THAN THAT OF SAID DEHYDRATED GAS EFFLUENT FROM THE FIRST BED.
