摘要:
A cryogenic air separation system wherein base load pressure energy is supplied to the feed air by a base load compressor and custom load pressure energy is supplied to the feed air by a bridge machine having one or more turbine booster compressors and one or more product boiler booster compressors, all of the compressors of the bridge machine driven by power supplied through a single gear case.

摘要:
A system for producing pressurized oxygen gas from low pressure oxygen gas without the need for engaging an oxygen compressor wherein low pressure oxygen gas is condensed by indirect heat exchange with a multicomponent refrigerant fluid, passed through a liquid pump, and then vaporized against that same multicomponent refrigerant fluid.
摘要:
A cryogenic rectification system for producing low purity oxygen and high purity oxygen employing an offset dual column with bottom reboil of the lower pressure column effected by condensing feed air, with intermediate reboil of the lower pressure column effected by condensing higher pressure column top vapor, and with waste nitrogen turboexpansion to generate refrigeration.

摘要:
A system for liquefying low boiling point gases wherein a mixture of feed gas and recirculating refrigerant gas is compressed, a first portion turboexpanded, a second portion compressed to a supercritical pressure, and the supercritical fluid cooled against the turboexpanded fluid to produce cryogenic liquid.
摘要:
A method and apparatus for producing a carbon monoxide containing product in which cathode and anode sides of an electrically driven oxygen separation device are contacted with carbon dioxide and a reducing agent, respectively. The carbon dioxide is reduced to carbon monoxide through ionization of oxygen and the reducing agent lowers the partial pressure of oxygen at the anode side to partially drive oxygen ion transport within the device through the consumption of the oxygen and to supply heat. The lowering of oxygen partial pressure reduces voltage and therefore, electrical power required to be applied to the device and the heat is supplied to heat the device to an operational temperature and to the reduction of the carbon dioxide occurring at the cathode side. The device can be used as part of an integrated apparatus in which the carbon dioxide is supplied from a waste stream of a process plant.
摘要:
In the production of fuel such as ethanol from carbonaceous feed material such as biomass, a stream comprising hydrogen and carbon monoxide is added to the raw gas stream derived from the feed material, and the resulting combined stream is converted into fuel and a gaseous byproduct such as by a Fischer-Tropsch reaction. The gaseous byproduct may be utilized in the formation of the aforementioned stream comprising hydrogen and carbon monoxide.
