Abstract
A method for removing noxious, hazardous, toxic, mutagenic, and/or carcinogenic compounds and/or precursor compounds from a comingled gas, liquid, and/or solid stream is described. In one embodiment, the method is used to prepare the stream for feeding to an oxidizer, such as a thermal oxidizer, to reduce the amount of particulate matter discharged by the oxidizer and includes passing the stream through an ambient or chilled temperature condenser followed by an optional gas/solid separator, and one or more gas scrubbers prior to feeding to the oxidizer.
Claims18
A method for reducing a concentration of one or more chemical compounds in a waste gas stream that are precursors to the formation of particulate matter emitted with the waste gas stream upon discharge to the atmosphere and for concurrently reducing a concentration of a vaporous odorous compound, comprising:
- passing a waste gas stream comprising a first chemical compound and a second chemical compound, wherein the first chemical compound is capable of reacting with the second chemical compound to form a particulate, and a vaporous odorous compound through an ambient temperature condenser;
- passing the waste gas stream from the condenser through a gas/solids separator;
- passing the waste gas stream from the gas/solids separator through a chilled condenser;
- passing the waste gas stream from the gas/solids separator through a particulate collection device;
- passing the waste gas stream from the particulate collection device through a wet scrubber to remove at least one of the first chemical compound or the second chemical compound, thereby reducing the reaction between the first and second chemical compound and reducing the formation of the particulate;
- passing the waste gas stream from the scrubber to a combustion device;
- and
- emitting the waste gas stream from the combustion device to the atmosphere.

- particulate matter;
- and a vaporous odorous compound through an ambient temperature condenser;
- passing the waste gas stream from the condenser through a gas/solids separator, thereby removing a portion of particulate matter from the waste gas stream;
- passing the waste gas stream from the gas/solids separator through a chilled condenser;
- passing the waste gas stream from the gas/solids separator through a particulate collection device;
- passing the waste gas stream from the particulate collection device through a wet scrubber to remove at least one of the first chemical compound or the second chemical compound, thereby reducing the formation of the particulate;
- passing the waste gas stream from the scrubber to a combustion device;
- and
- emitting the waste gas stream from the combustion device to the atmosphere.
