摘要:
A method and system for collecting gaseous nitrogen compounds into an aqueous solution are provided. The method enables the combination of gaseous sulfur and nitrogen compounds in the aqueous solution to generate ammonium compound components, to include ammonium sulfate. Sulfur may be pressure injected into the solution as gaseous sulfur dioxide. Optionally, carbon may be introduced into the solution as gaseous carbon dioxide. The sulfur may be earlier sourced by a burning of a sulfurous solid. The pH of the solution may be monitored and the introduction of ammonia, carbon and/or sulfur may be halted or constrained while the pH of the solution is measured outside of specified range. The solution may be allowed to age to permit a mix of compounds of ammonium carbonate, ammonium bicarbonate and ammonium carbomate to restabilize and thereby encourage a renewed surge of ammonium sulfate generation.
