AI Technical Summary

Technical Problem

Existing methods for removing components from gas streams, particularly in industrial and waste gas streams, are energy-intensive and result in costly disposal of liquid and gas streams, posing challenges for compliance with organic farming regulations and increasing production costs.

Method used

A method involving absorption or scrubbing techniques to remove targeted compounds like ammonia from gas streams into a liquid scrubbing solution, which is then recycled to produce a liquid stream that can be used as a fertilizer, compliant with organic farming standards.

Benefits of technology

The method effectively recovers ammonia from gas streams, reducing wastewater discharge and producing a natural fertilizer suitable for organic agriculture, while minimizing energy consumption and compliance costs.

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.
