Gas scrubber system and method

摘要

A system for treating a biogas stream is described. The system includes a venturi device in communication with a biogas stream source and an influent water source to combine the biogas stream and the influent water to produce a gas-water effluent. The system also includes a degas separator in communication with the venturi device for receipt of the gas-water effluent to produce a relatively low solubility gas effluent and a relatively high solubility gas-water mixture effluent. In addition, the system includes a gas-water pressure release valve in communication with the degas separator to control release of the relatively low solubility gas effluent and a discharge pressure control valve in communication with the degas separator to control release of the relatively high solubility gas-water mixture effluent.

1. A system for treating a biogas stream, comprising:
a biogas stream source comprising a municipal wastewater treatment facility, wherein the biogas stream comprises methane, carbon dioxide, and siloxanes and is produced from the anaerobic decomposition of organic matter; an influent water source comprising the municipal wastewater treatment facility; a venturi device in communication with the biogas stream source and the influent water source to combine the biogas stream and the influent water to produce a gas-water effluent; a degas separator in communication with the venturi device for receipt of the gas-water effluent to produce a relatively low solubility gas effluent and a relatively high solubility gas-water mixture effluent; a gas-water pressure release valve in communication with the degas separator to control release of the relatively low solubility gas effluent; and a discharge pressure control valve in communication with the degas separator to control release of the relatively high solubility gas-water mixture effluent.
