Odor removal system and method

An odor removal system comprising:

• a liquid contact tank;
• a volume of said iron chelating liquid disposed within said tank;
• a sparging device disposed within said tank and within said volume of said iron chelating liquid;
• a venturi generator having first and second inlet ports and an outlet port, the sparging device being fluidly coupled to the outlet port of said venturi generator;
• a blower having an outlet fluidly coupled to the second inlet port of said venturi generator;
• a circulation pump having an inlet and an outlet, the inlet of the circulation pump being fluidly coupled to the tank at or near the bottom of the tank and the outlet of the circulation pump being fluidly coupled to the tank;
• whereby
• a source of said odorous gas may be fluidly coupled to the first inlet port of said venturi generator;
• operation of the blower creates a suction at the first port of the venturi generator and is operable to draw the odorous gas into the tank via the sparging device;
• and
• operation of said circulation pump prevents stagnation of said iron chelating liquid.

A method for removing odors from a gas containing sulfur compounds, comprising:

• providing a liquid contact tank having a sparging device disposed therein;
• filling a volume of iron chelating liquid within said tank so as to cover said sparging device with said liquid;
• and
• introducing said gas containing sulfur compounds into said iron chelating liquid through said sparging device;
• whereby
• said sulfur compounds interacting with the volume of iron chelating liquid, which absorbs the sulfur compounds and removes odor from the gas.
