Abstract
The present invention is directed to methods for treating a gas stream by removing one or more targeted compounds from the gas stream into a liquid scrubbing solution. Such treatment of the gas stream may be performed to produce a liquid stream generated from or separated from the liquid scrubbing solution that comprises an absorbed form of the targeted compound that can be used directly or after further processing as a product, such as a commercial or saleable product, such as a fertilizer.
Claims1
A method for producing a fertilizer from a gas stream comprising a nitrogen-based compound, comprising:
- providing a liquid solution comprising oligomers of an organic acid;
- degrading at least a portion of the oligomers in the solution into monomers of the acid to generate a solution comprising the monomers of the acid;
- adding the solution comprising monomers of the acid to a scrubbing solution;
- contacting the scrubbing solution with a gas stream comprising a gaseous nitrogen-based compound;
- absorbing the nitrogen-based compound into the scrubbing solution;
- producing a disassociated form of the absorbed nitrogen-based compound based upon the compositions of the monomers of the acid and the nitrogen-based compound in the scrubbing solution;
- and
- separating at least a portion of the scrubbing solution comprising the disassociated form of the absorbed nitrogen-based compound, thereby creating a liquid fertilizer.
