摘要： Non-hazardous organic waste material is introduced through a line (7) into a slagging combustion chamber (11) where it is burned. The burning produces exhaust gases and a slag of molten, inorganic ash which is removed from the combustion chamber (11) by a line (12) connected to the bottom of the combustion chamber (11). The exhaust gases flowing out through line (13) are treated to remove most of the particulate matter contained in the gases. A portion of the treated gases is mixed with concentrated oxygen from air separation unit (38) in a proportion that results in mixed gases having an oxygen concentration of at least 30 % by volume. The mixed gases are then introduced into the combustion chamber (11) to support the burning of the waste material.

摘要： The method of the invention recovers CO 2 from an inlet cold feed stream containing a low concentration thereof, and includes the following steps. An inlet feed stream is passed through a heat exchanger, against a compressed flow of the inlet feed stream, to cool the compressed flow. The compressed flow is further cooled and compressed to a high pressure, fed to a distillation column and there converted into a vent gas including CO 2 and a high purity bottom liquid CO 2 . A first portion of the bottom liquid CO 2 is expanded to achieve a first cooled liquid CO 2 refrigerant flow, which is then vaporized against the vent gas to recover condensed CO 2 therefrom. The condensed CO 2 is then reintroduced into the distillation column. A second portion of the bottom liquid CO 2 is expanded to achieve a second cooled liquid CO 2 refrigerant flow, which is then used to subcool the CO 2 product output.

摘要： A cryogenic air separation unit (ASU) (10) provides oxygen (12) for use in a process (14), such as COREX iron making or the partial oxidation of hydrocarbons, or in an oxycoal fuelled blast furnace, producing an off-gas (16) containing useful components (H 2 and CO) and carbon dioxide. The carbon dioxide is removed by pressure swing adsorption (20) using nitrogen (22) from the ASU (10) as a regeneration gas and the purified off-gas (26) used a feed gas to a further process (28) such as production of iron by direct reduction of iron ore or the production of a NH 3 making ammonia or is recycled into the first process as a feed gas.

摘要： This invention relates to a method for producing a hydrogen stream and a carbon dioxide stream from a mixed gas feedstock containing hydrogen, carbon dioxide, and contaminant sulfur compounds. The method comprises scrubbing the gas feedstock with a carbon dioxide laden solvent in an initial scrubbing zone under conditions such that not more than 70% of the carbonyl sulfide in the feedstock is removed in the initial zone, physically scrubbing the initially scrubbed feedstock with a solvent under conditions sufficient for removing substantially all the carbon dioxide and carbonyl sulfide therefrom to leave a pure hydrogen stream desorbing carbon dioxide and carbonyl sulfide and other gases from the liquid from the second scrubbing zone and then fractionating the resultant carbon dioxide stream containing hydrogen, carbon oxides, etc. to produce said carbon dioxide stream for use in urea synthesis.

摘要： A pressurized high purity liquid carbon dioxide streams produced by purifying a feed stream composed of carbon dioxide vapor within a purifying filter (12) and then condensing it within a condenser (20). The resulting liquid is then alternately introduced and dispensed from two first and second pressure accumulation chambers (28,30). The first and second pressure accumulation chambers (28,30) are heated by electrical heaters (32,34) to pressurize the liquid to the required or desired delivery pressure of the pressurized liquid carbon dioxide stream. Such stream is alternately extracted from the first and second pressure accumulation chambers (28,30) on a continuous basis in which one of the first and second pressure accumulation chambers (28,30) acts in a dispensing role while the other is being filled. The pressurized liquid carbon dioxide stream can be further filtered within a particulate filter.

摘要： This invention relates to an improvement in a process and apparatus for delivering ultra high purity liquid carbon dioxide to a point of use at pressures above ambient without pumping. In the process a high purity carbon dioxide feed is charged to a vessel and at least partially solidified. Once filled, the slush or solid is isochorically heated, i.e., heated at constant vessel volume whereby the solid phase carbon dioxide is converted to a liquid. Liquid, then, is withdrawn from the vessel at a desired pressure at a rate at which the solid phase carbon dioxide is converted to a liquid. The improvement resides in effecting partial solidification and recycle of carbon dioxide.
