Method For Producing High Purity Biomethane Without Adding Unacceptable Quantities Of Moisture
US Patent:
2013006, Mar 7, 2013
Filed:
Nov 5, 2012
Appl. No.:
13/668476
Inventors:
Stearns Conrad Schmidt Consulting Engineers, In - Long Beach CA, US
Jeffrey L. Pierce - Torrance CA, US
Jeffrey L. Pierce - Torrance CA, US
Assignee:
STEARNS CONRAD SCHMIDT CONSULTING ENGINEERS, INC. - Long Beach CA
International Classification:
C07C 7/12
US Classification:
585802
Abstract:
A method for producing high purity biomethane using two non-regenerative media in series to reliably and virtually completely eliminate undesirable impurities from biomethane. The first media in the series is activated carbon, preferably virgin media, produced from coconut shells or coal. The second media in the series is silica gel or other desiccant. Neither material is regenerated; rather, the purity of the biomethane is monitored and when the media is spent, the media is discarded.
