摘要: A process for the production of synthesis gas from a hydrocarbon fuel and steam and/or oxygen gas wherein at least part of any steam requirement is provided by heat exchange against exhaust gas from a gas turbine driving an air separation unit supplying at least part of any oxygen requirement for the synthesis gas production. The process is particularly applicable when the synthesis gas is used to prepare a synfuel by methanol synthesis or a Fischer-Tropsch process.

摘要: A process for generating power from the expansion of steam in a steam turbine system. The steam is generated by at least partially vaporizing pre-heated water by heat exchange against a first fuel gas that is generated exothermically. The at least partially vaporized water is then heated to produce the steam by heat exchange against expanded combustion product gas that is generated by the combustion of a second fuel gas in the presence of compressed oxygen-containing gas and the subsequent expansion of the combustion product gas. The steam is then expanded in a steam turbine system having more than one pressure stage to produce power and an expanded steam stream.

摘要: A process for the adsorption of at least carbon dioxide, water and oxides of nitrogen and preferably acetylene from a feed gas, comprises contacting the feed gas with an adsorbent mixture of a zeolite and an alumina. The process may be operated as a swing adsorption process comprising contacting the gas with the adsorbent at a first temperature and pressure to adsorb at least carbon dioxide, water and oxides of nitrogen therefrom and periodically regenerating the adsorbent by reducing the pressure and or increasing the temperature to which the adsorbent is exposed.

摘要: A first contaminant selected from oxygen and carbon monoxide is removed from impure liquid carbon dioxide using a mass transfer separation column system which is reboiled by indirect heat exchange against crude carbon dioxide fluid, the impure liquid carbon dioxide having a greater concentration of carbon dioxide than the crude carbon dioxide fluid. The invention has particular application in the recovery of carbon dioxide from flue gas generated in an oxyfuel combustion process or waste gas from a hydrogen PSA process. Advantages include reducing the level of the first contaminant to not more than 1000 ppm.

摘要: A superheater in a power plant that superheats steam to operation conditions exceeding an operating limit of an associated steam-producing boiler. The superheater combusts oxygen and fuel with cooled recycled combustion gas to produce a CO2-rich combustion product gas stream at a fixed temperature. The combustion gas is used as the heat transfer fluid in the superheater's heat exchanger. The CO2-rich flue gas stream allows for efficient capture of substantially pure CO2. The superheater may be retrofitted to an existing power plant as a separate component, external to the boiler. The plant may thus have its electrical power output increased, while its overall CO2 emissions per nit of generated power is decreased, even when inexpensive, readily-available fossil fuels are used as the primary fuel for filing the boiler and/or the superheater.

摘要: Impure carbon dioxide (“CO2”) comprising a first contaminant selected from the group consisting of oxygen (“O2”) and carbon monoxide (“CO”) is purified by separating expanded impure carbon dioxide liquid in a mass transfer separation column system. The impure carbon dioxide may be derived from, for example, flue gas from an oxyfuel combustion process or waste gas from a hydrogen (“H2”) PSA system.
