Abstract: A biogas treatment system removes moisture and other unwanted materials from biogas originating, for example, with a landfill or anaerobic digester. Water and other unwanted materials are thus removed from landfill gas and waste water biogas, while the gas temperature is controlled to a usable level. More especially, the present invention provides for the removal of water and other unwanted ingredients of biogas with a greatly reduced energy requirement when compared to conventional technologies.

Abstract: A modular turbine generator includes both a turbo generator, and electrical power conditioning and control circuitry. During conditions of high ambient temperature the turbo generator may lose both power output and efficiency, while the electrical circuitry suffers from shortened service life or failure because of the high temperatures experienced. In order to preserve power output and efficiency for the turbo generator, as well as extending the service life span for the electrical power conditioning and control circuitry, a dual function evaporative cooler is provided. This cooler provides evaporatively cooled air both to the turbine engine and to the electrical circuitry by utilizing a single evaporative pad, along with a single water source and recirculation pump, all received in a compact cabinet.
