Abstract
Disclosed is a method for removing inorganic acid-forming constituents from a gas stream contaminated therewith (e.g. high sulfur coal effluent). Such removal is accomplished by passing the gas stream through an active composting biodegradable organic waste held under thermophilic bacteria-phase digestion conditions. Also disclosed is a comprehensive composting treatment site which desirably employs a windrowing composting technique and is suitably adapted to be operated with the gas stream scrubbing process disclosed herein.
Claims11
A method for removing an inorganic acid-forming moeity from a gas stream contaminated therewith, said moeity being or capable of forming an inorganic acid in the presence of molecular oxygen and water, and for producing a compost product from substantially non-digest biodegradable organic waste comprising municipal waste and industrial waste, which comprises:
- a. admitting at least intermittently biodegradable organic waste into an active composting treatment site;
- b. maintaining said waste under thermophilic bacteria-phase digestion conditions including adequate aeration and agitation, a water content by weight of between about 30% and 70%, and a temperature of between about 30.degree. and 70.degree. C., for a time adequate for said waste to be substantially digested;
- c. passing said contaminated gas stream through said digesting waste while maintaining said digestion conditions, the contact time therebetween being adequate for substantially removing said moeity from said gas stream;
- d. venting a product gas stream substantially free of said moeity from said waste;
- and
- e. removing at least intermittently said compost product from said site.
