    摘要： A batch process and apparatus for producing a pressurized liquid carbon dioxide stream includes distilling a feed stream of carbon dioxide vapor off of a liquid carbon dioxide supply; introducing the carbon dioxide vapor feed stream into at least one purifying filter; condensing the purified feed stream within a condenser to form an intermediate liquid carbon dioxide stream; introducing the intermediate liquid carbon dioxide stream into at least one high-pressure accumulation chamber; heating the high pressure accumulation chamber to pressurize the liquid carbon dioxide contained therein to a delivery pressure; delivering a pressurized liquid carbon dioxide stream from the high-pressure accumulation chamber; and, discontinuing delivery of the pressurized liquid carbon dioxide stream for replenishing the high pressure accumulation chamber.

    摘要： The present invention provides a method and apparatus for producing a pressurized high purity liquid carbon dioxide stream in which a feed stream composed of carbon dioxide vapor is purified within a purifying filter and then condensed within a condenser. The result liquid is then alternately introduced and dispensed from two first and second pressure accumulation chambers. The first and second pressure accumulation chambers are heated by electrical heaters 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 on a continuous basis in which one of the first and second pressure accumulation chambers 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： A carbon dioxide recovery apparatus and process for supercritical extraction includes providing a process stream from a supercritical extraction procedure in which the process stream includes pressurized carbon dioxide, extraction process waste and optionally at least one co-solvent; reducing the pressure of the process stream below critical pressure; venting low pressure carbon dioxide vapor to exhaust; cooling the process stream to form a two phase mixture; separating the two phase mixture into a process liquid, containing co-solvent if present, and a process vapor phase stream; collecting the process liquid; filtering the process vapor phase stream to remove particulates and optionally residual co-solvent; passing the filtered process vapor stream through an adsorber to remove trace impurities to form a purified carbon dioxide vapor stream; and, drying the purified carbon dioxide vapor stream to remove residual water vapor.
