Abstract
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. This is accomplished primarily by directing the exhaust gas from a fossil fuel fired power plant through both a reaction chamber containing a chemically produced compound and a catalytic converter. 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.
Claims17
A process for exhaust 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 a different source to the wet scrubber;
- mixing water from a remote source in the wet scrubber with the exhaust gas and the chemically produced compound;
- bypassing a chemically produced byproduct from the wet scrubber to storage;
- directing the chemically modified exhaust gas from the wet scrubber to a reaction chamber to chemically modify the exhaust gas;
- adding a reacting compound to the reaction chamber for modification of the exhaust gas therein and chemically produced compound;
- bypassing the chemically produced compound from the reaction chamber to the wet scrubber as the different source for the chemically produced compound;
- adding a catalytic converter in the flow path of the exhaust gas downstream of one of the wet scrubber and the reaction chamber;
- and
- exhausting the final chemically safe exhaust gas to the atmosphere.
An exhaust gas clean-up system adapted for use with a fossil fuel fired power plant, consisting of:
- a reaction chamber connected to the fossil fuel fired power plant and operative to receive and direct the exhaust gas therethrough, to receive a reacting compound from a remote source to chemically react with the exhaust gas therein, and to bypass a chemically produced compound to one of a storage tank and a wet scrubber;
- and
- a catalytic converter connected to the reaction chamber downstream thereof, wherein the treated exhaust gas being directed through the catalytic converter contains nitrogen oxides which are converted into atmosphere safe nitrogen and oxygen.
