Benefits of technology

The patent is about a method and system for treating exhaust gas from stationary engines used to generate electricity. The method involves capturing the exhaust gas and routing it to an absorption tower, where water is sprayed onto the gas as it travels upwards through the tower. The water contains nitrous oxides, sulfur dioxides, and particulates removed from the exhaust gas. Some of the water collected at the bottom of the tower is then reused to spray water back into the absorption tower. The system includes an absorption tower with plates, spray nozzles, and a water outlet. The method and system help to reduce emissions and improve air quality.

Problems solved by technology

Additionally, fine carbon particulate is released during fossil fuel power production (esp. coal plants) and is a significant contributor to lung-related health problems and also causes negative environmental impacts such as acid rain and neutralizing glacial / arctic albedo.

Embodiment Construction

[0008]FIG. 1 illustrates a system for treating exhaust gases produced by one or more stationary combustion engines 10 that are used to produce electricity. Each stationary combustion engine 10 could be fueled by a range of acceptable fuels, but in one aspect each combustion engine 10 is fueled by natural gas. The system can capture the entire exhaust stream, remove contaminants from the exhaust stream and convert some of the output into transportable liquid products containing contaminants from the exhaust stream.

[0009]In the system, all of the exhaust gases from the one or more stationary combustion engines 10 are routed through at least one exhaust conduit 102 to an absorption tower 100 where the exhaust gas is treated. In an interior 108 of the absorption tower 100, the exhaust gas is allowed to pass upwards inside the absorption tower 100 as water is being sprayed on perforated plates 130 in the rising exhaust gas creating a chemical reaction binding the pollutants in the exhaus...

Abstract

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.

Description

FIELD[0001]The present invention relates to a system and method for treating exhaust gas and more particularly to a system and method for removing nitrous oxides, particulates and other pollutants from exhaust gas formed from the combustion of natural gas.BACKGROUND[0002]Existing fossil fuel power plants allow exhaust to be released into the atmosphere. In these emissions, oxides of nitrogen, carbon dioxide, sulfur dioxide and water vapor are all prime contributors to the greenhouse effect and could cause anthropogenic climate change. This technology would provide a useful means of capturing and diverting greenhouse effect contributors into a controllable liquid. While this is not a permanent sequestration, control of the resource is a fundamental first step in that process.[0003]Additionally, fine carbon particulate is released during fossil fuel power production (esp. coal plants) and is a significant contributor to lung-related health problems and also causes negative environment...
