Abstract
Abstract An absorber fluid circuit is provided for a volatile liquid vapor recovery system. The vapor recovery system includes at least one adsorbent bed for capturing volatile liquid vapor, a vacuum pump for regenerating the adsorbent bed, a heat exchanger for cooling the vacuum pump, an absorber tower for condensing volatile liquid vapor and an absorber fluid source. The absorber fluid circuit includes an absorber fluid supply pump and a first conduit for directing absorber fluid from the absorber fluid source to the supply pump. A second conduit directs absorber fluid from the supply pump to both the heat exchanger and absorber tower. A third conduit returns spent absorber fluid from the heat exchanger and absorber tower back to the absorber fluid source.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
138 words
In a volatile liquid vapor recovery system including at least one adsorbent bed, a vacuum pump for regenerating the bed, a heat exchanger for cooling the vacuum pump, an absorber tower for condensing volatile liquid vapor and an absorber fluid source, the improvement comprising: an absorber fluid circuit including; (a) an absorber fluid supply pump having an inlet and an outlet; (b) first conduit means for connecting said inlet of said supply pump to the absorber fluid source; (c) second conduit means for connecting said outlet of said supply pump to the heat exchanger and absorber tower; and (d) third conduit means for returning spent absorber fluid from the heat exchanger to the absorber fluid source while always bypassing the absorber tower and from the absorber tower to the absorber fluid source while always bypassing the heat exchanger.
Claim 2
Dependent Claim
138 words
In a volatile liquid vapor recovery system including at least one adsorbent bed, a vacuum pump for regenerating the bed, a heat exchanger for cooling the vacuum pump, an absorber tower for condensing volatile liquid vapor and an absorber fluid source, the improvement comprising: an absorber fluid circuit including; (a) an absorber fluid supply pump having an inlet and an outlet; (b) first conduit means for connecting said inlet of said supply pump to the absorber fluid source; (c) second conduit means for connecting said outlet of said supply pump to the heat exchanger and absorber tower; and (d) third conduit means for returning spent absorber fluid from the heat exchanger to the absorber fluid source while always bypassing the absorber tower and from the absorber tower to the absorber fluid source while always bypassing the heat exchanger.
Claim 3
Dependent Claim
27 words
