EXHAUST GAS CLEAN-UP SYSTEM FOR FOSSIL FUEL FIRED POWER PLANT

摘要

A fossil fuel fired power plant exhaust gas clean-up system is provided to remove detrimental compounds/elements from the exhaust gas emitting from the power plant to protect the environment. The removal of detrimental compounds/elements is accomplished by directing the exhaust gas thought several process steps. For example, one step includes a wet scrubber that includes the exhaust gas, water, and a chemically produced compound. The chemical reaction therein is effective to remove sulfur from the exhaust gas and as a side benefit, a useful by-product is produced and stored. Another step directs the remaining exhaust gas through a catalytic converter that is effective to convert nitrogen oxide to nitrogen gas and converts carbon monoxide into carbon dioxide. The final step includes directing the remaining exhaust gas into a reaction chamber with the addition of a reacting compound to remove the carbon dioxide and produce a chemical compound that is used in the first step. The final exhaust gas can now be safely exhausted to the atmosphere and only contains nitrogen gas, oxygen, water and a trace amount of carbon dioxide.

主权项

1. A process for gas clean-up of a fossil fuel fired power plant, comprising the steps of:
directing the exhaust gas from the fossil fuel fired power plant through a wet scrubber; adding a chemically produced compound from another source to the wet scrubber; adding water from a remote source to the wet scrubber to mix with the exhaust gas and the chemically produced compound; bypassing a chemically produced byproduct from the wet scrubber; directing the chemically modified exhaust gas through a catalytic converter to further chemically modify the exhaust gas from the wet scrubber; directing the further chemically modified exhaust gas to a reactor chamber for additional modification; adding a reacting compound to the reaction chamber to aid in the additional modification of the exhaust gas therein; bypassing the chemically produced product from the reactor chamber to the wet scrubber to severe as the another source noted above; and exhausting the final chemically modified exhaust gas to the atmosphere.
