Abstract:
1. A method of purifying and conditioning a stream of air containing contaminants, comprising: wetting a filter packing media with a liquid desiccant comprising a concentration of a salt; directing the stream of air to flow through the wetted filter packing media; concurrently with the directing, capturing a fraction of the contaminants in the stream of air in the liquid desiccant; concurrently with the capturing, dehumidifying the stream of air with the liquid desiccant in the filter packing media; deactivating at least a portion the captured contaminants including heating at least a portion of the liquid desiccant with the captured contaminants to a deactivation temperature, wherein the deactivating includes after the capturing, collecting the liquid desiccant with the captured contaminants, pumping the collected liquid desiccant to a capture filter, and heating the filter to the deactivation temperature; regenerating the liquid desiccant including applying a quantity of heat and removing moisture from the liquid desiccant; and repeating the wetting with the regenerated liquid desiccant.
