EXHAUST GAS TREATMENT SYSTEM

摘要

A method and system for treating exhaust gas from stationary engines used to generate electricity is provided. Substantially all of the exhaust gases from at least one stationary combustion engine used for electrical power generation are collected and routed to an absorption tower. Inside the absorption tower the exhaust gases travel upwards in and through a plurality of perforated plates to a gas outlet in a top of the absorption tower. While the gas is ascending in the absorption tower, water is sprayed on the ascending gas and the perforated plates and this water is collected in the bottom of the absorption tower where at least some of it will be reused by spraying it back into the absorption tower to treat more exhaust gas from the combustion engines.

1. A method for treating exhaust gas from stationary engines used to generate electricity, the method comprising:
capturing substantially all of the exhaust gases from at least one stationary combustion engine used for electrical power generation and routing substantially all of the exhaust gases to an absorption tower; allowing the exhaust gases to travel upwards in an interior of the absorption tower through a plurality of perforated plates to a gas outlet in a top end of the absorption tower; spraying water on the plurality of perforated plates and the exhaust gas as it travels upwards in the absorption tower; collecting water that was sprayed in the absorption tower in a bottom end of the absorption tower, the water containing nitrous oxides, sulfur dioxides and particulates removed from the exhaust gas; and reusing at least a portion of the water collected in the bottom end of the absorption tower to spray the at least a portion of the water back into the interior of the absorption tower.
