Abstract
Abstract There is disclosed an improved hydrocarbon vapor collection and disposal system consisting of a hydrocarbon vapor circulation loop disposed between a hydrocarbon vapor storage area and a vapor disposal unit such as an incinerator or a liquefication unit. The system is also provided with means for activating the disposal unit when hydrocarbon vapors are passed from the hydrocarbon liquid dispensing unit into the circulation loop.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
80 words
A device for increasing the concentration of hydrocarbons in a stream of lean hydrocarbon vapors prior to the disposal of said vapors comprising: a circulation loop disposed between a liquid hydrocarbon storage tank and a disposal unit; a vapor pumping means for pumping hydrocarbon vapors in said circulation loop; a vapor inlet for introducing said lean vapors into said circulation loop; and means for activating said disposal unit only when said lean hydrocarbon vapors are passed into said circulation loop.
Claim 2
Independent Claim
80 words
A device for increasing the concentration of hydrocarbons in a stream of lean hydrocarbon vapors prior to the disposal of said vapors comprising: a circulation loop disposed between a liquid hydrocarbon storage tank and a disposal unit; a vapor pumping means for pumping hydrocarbon vapors in said circulation loop; a vapor inlet for introducing said lean vapors into said circulation loop; and means for activating said disposal unit only when said lean hydrocarbon vapors are passed into said circulation loop.
Claim 3
Dependent Claim
12 words
The system of claim 1 wherein said disposal unit is an incinerator.
Claim 4
Dependent Claim
13 words
The system of claim 1 wherein said disposal unit is a liquefication unit.
Claim 5
Dependent Claim
75 words
An improved method for increasing the concentration of hydrocarbons in a stream of lean hydrocarbon vapors prior to the disposal of said vapors comprising: circulating rich hydrocarbon vapors in a circulation loop disposed between a liquid hydrocarbon storage tank and a disposal unit; passing said lean vapors into said circulation loop and mixing said lean vapors with said rich vapors; and activating said disposal unit when said lean vapors are passed into said circulation loop.
Claim 6
Dependent Claim
75 words
An improved method for increasing the concentration of hydrocarbons in a stream of lean hydrocarbon vapors prior to the disposal of said vapors comprising: circulating rich hydrocarbon vapors in a circulation loop disposed between a liquid hydrocarbon storage tank and a disposal unit; passing said lean vapors into said circulation loop and mixing said lean vapors with said rich vapors; and activating said disposal unit when said lean vapors are passed into said circulation loop.
Claim 7
Dependent Claim
12 words
