Systems and methods for managing hydrocarbon emissions

A system for reducing the release of hydrocarbons intermittently or continuously emitted from a hydrocarbon source into the atmosphere, the system comprising:

• a hydrocarbon supply conduit configured to receive the emitted hydrocarbons from the hydrocarbon source;
• an air supply conduit configured to receive air from an air source;
• an aspirator fluidly coupled to the air supply conduit and the hydrocarbon supply conduit, wherein the aspirator is configured to (i) receive air from the air supply conduit, (ii) receive the emitted hydrocarbons from the hydrocarbon supply conduit, and (iii) mix the air with the emitted hydrocarbons to form an air-hydrocarbon mixed stream;
• a mixing tee fluidly coupled to the air supply conduit, the hydrocarbon supply conduit, and the aspirator, wherein the mixing tee is configured to (i) receive the air-hydrocarbon mixed stream from the aspirator, (ii) receive supplemental air from the air supply conduit, and (iii) mix the supplemental air and the air-hydrocarbon mixed stream to form an air-entrained hydrocarbon stream;
• an air-entrained hydrocarbon conduit fluidly coupled to the mixing tee;
• and
• a catalytic converter fluidly coupled to the air-entrained hydrocarbon conduit and configured to receive the air-entrained hydrocarbon stream, and wherein the catalytic converter includes a catalyst configured to catalytically combust and oxidize the emitted hydrocarbons in the air-entrained hydrocarbon stream;
• and
• a gas capture device fixably coupled to the catalytic converter and configured to capture gases emitted from the catalytic converter, wherein the gas capture device comprises an inverted cup having a cylindrical wall and an end-cap fixed to a first end of the cylindrical wall so as to define an inner chamber in which the catalytic converter is disposed.
