    Abstract: A zero-emissions power plant receives natural gas from wells at elevated pressure and temperature. Gas is expanded through one or more turbo-expanders, preferably reformed, and sent to a fuel cell where electricity, heat, carbon-dioxide, and water are generated. The carbon-dioxide is compressed by at least one compressor and piped downhole for sequestration. The turbo-expanders have shafts which preferably share the shafts of the compressors. Thus, energy given up by the natural gas in the turbo-expanders is used to run compressors which compress carbon dioxide for downhole sequestration. In one embodiment, the natural gas is applied to heat exchangers in order to generate a stream of liquid natural gas. The remainder of the gas is expanded through the turbo-expanders and processed in the reformer prior to being sent to the fuel cell. A shifter may be used between the reformer and fuel cell. A solid oxide fuel cell is preferred.

    Abstract: A building having an energy conversion apparatus and method for distributed energy systems using recovered energy of stationary structure wind resistance and solar radiation in conjunction with normal and off-peak operation of a gas turbine engine. The energy sources are combined, as available, for electric generation and to drive an air liquefier. Liquid air compression and pre-compression cooling of an atmospheric air portion of engine working fluid reduces compression work while increasing engine efficiency. The liquefied air is stored and transferred between buildings and between buildings and vehicles, as required.

    Abstract: Process for the purification of natural hydrocarbon gases which, as may be produced at a wellhead, are contaminated by substantial proportions of incombustible constituents such as nitrogen. Contaminated gas at elevated pressure is condensed by cooling in two steps, thereafter expanded to approximately atmospheric pressure to effect phase separation between a hydrocarbon-rich liquid and a contaminant-rich vapor. The hydrocarbon-rich liquid is partially vaporized and a second phase separation yields a liquid enriched in hydrocarbon. The vapor from the second separation is cooled and returned to the first separation while the vapor product from first separation along with the liquid product from the second separation are separately employed to effect condensation of the contaminated hydrocarbon.
