20080289504 | Regenerable purification system for removal of siloxanes and volatile organic carbons - A process to purify biogases (i.e., landfill gas and municipal digester gas), to 5 enable such biogases to be utilized to generate electricity and heat. Biogases from these sources generally include small amounts of organosilicons (which are particularly harmful to power generation equipment, and especially harmful to micro-turbines, reciprocating internal combustion engines, and large turbines), and halogenated chemical species (which can foul expensive emission catalysts). A fluidized media bed reactor is configured to concentrate offending organics, and is coupled with another reactor vessel configured to strip the offending organics off saturated media with a hot inert gas. The removed organics are further concentrated into an inert gas stream that is conveyed to a small flare for greater than 99% destruction. The energy required to strip the organics from the spent media, and to energize the flare, is generated by the combustion of a small quantity of the purified biogas. | 11-27-2008 |

20090145300 | Process and Apparatus for Generating and Delivering An Enriched Gas Fraction - An improved sieve bed design to manage breakthrough and the mass transfer zone by way of volumetric division. An empty space in the product end is separated from adsorbent-filled sieve space in the feed end by a mid-diffuser plate. The ratio of the empty product end void space to the adsorbent filled sieve space within a sieve bed may be determined by the relative percentages of the gasses to be separated and the bulk loading factor of the molecular sieve. A product end void space of the correct volume may ensure the maximum volume of nitrogen has been adsorbed before breakthrough occurs. In operation, pressure in the sieve bed empty space and sieve filled space may be equal at any instant. This contains breakthrough to the location of the mid-diffuser plate. The mass transfer zone may be static at the point of the mid-diffuser plate and as such, gas separation is a function of pressure within the bed. | 06-11-2009 |
