Fiberbed mist collector with improved filtering

A method of filtering gas comprising:

• a. providing a fiberbed mist collector comprising:
• a housing having:
• a housing inlet through which the gas emissions enter the housing;
• a pre-filter area for receiving gases prior to pre-filtering, wherein the pre-filter area is configured to reduce a velocity of gas emissions;
• a transition area for receiving gas emissions from the pre-filter area prior to primary filtering;
• a primary filter area provided with one or more primary filters;
• a liquid collecting chamber disposed vertically below the primary filter area and configured to collect liquid waste material falling from the primary filter area;
• and
• a housing outlet through which the gas emissions exit the housing;
• an exhaust stack having a stack inlet attached to and in fluid communication with the housing outlet of the housing for receiving gas emissions from the housing, an exhaust fan, and a stack exit through which gas emissions exit the exhaust stack;
• one or more pre-filters located between the pre-filter area and the transition area, wherein gas emissions flowing from the pre-filter area to the transition area must pass through the one or more pre-filters and wherein the one or more pre-filters are configured to filter out particulate matter that is entrained with the gas emissions;
• one or more condensing filters disposed in the primary filter area and configured to condense at least a portion of the gas emissions;
• and
• at least one acid-impregnated filter configured to remove at least one non-condensing gas from the gas emissions;
• b. providing a gas emission having contaminants, including one or more unwanted gases;
• and
• c. using the fiberbed mist collector removing a portion of at least one of the contaminants from the gas emission.
