摘要： Systems and methods are provided for recovering helium from a feed comprising helium, carbon dioxide, and at least one intermediate component having a volatility between those of helium and carbon dioxide. In particular, processes of the present invention comprise separating the carbon dioxide and the components of intermediate volatility from the helium at a temperature greater than −82.7° C. to form a helium-rich product stream, wherein the concentration of at least one of the intermediate components in the helium-rich product stream is lower than its concentration in the feed stream, and wherein at least part of the separation is effected by contacting a vapor with a liquid.

摘要： A storage vessel comprises a condenser for condensing boil-off vapor by direct heat exchange with cryogenic liquid feed to the vessel. The condenser comprises a packed arrangement of vapor-liquid contact packing that comprises a top end portion and a bottom end portion. At least said top end portion is open to the vapor space to allow entry of boil-off vapor into the arrangement. The bottom end portion is in fluid flow communication with the lower portion of the storage vessel. One advantage of the invention is that the condenser is open to the vapor space of the storage vessel thereby allowing boil-off vapor to be drawn into the condenser by the condensation action of the vapor.

摘要： A process for the cryogenic distillation of air uses a distillation column system having a supplemental column and a distillation unit including a lower-pressure column and a higher-pressure column. A liquid stream enriched in oxygen is withdrawn from the lower-pressure column and is eventually vaporized through indirect latent heat transfer, thereby producing a reflux stream, a portion of which is eventually sent to the lower-pressure column, the higher-pressure column, and/or the supplemental column. At least a portion of the reflux for the supplemental column is eventually derived from the distillation unit. A nitrogen-enriched liquid removed from the distillation unit is increased in pressure and is fed to the supplemental column or back to the distillation unit. An oxygen-enriched fluid from the bottom of the supplemental column is fed to the distillation unit. At least some of the nitrogen product from the supplemental column is returned to the distillation unit.

摘要： A first stream of air is compressed in a main air compressor and a booster compressor is cooled at a first pressure by passage through a main heat exchanger. The cooled stream is introduced without further compression into the higher pressure column of a double rectification column including in addition to the column a lower pressure column and a condenser-reboiler. A second stream of compressed air is expanded from a second pressure in an expansion turbine with the performance of external work. The expanded second stream of air is introduced into the lower pressure column. An oxygen product, typically impure, is taken from the bottom region of the lower pressure column. The second pressure is less than the first pressure column. The second pressure is less than the first pressure, the second air stream being taken from intermediate the compressors.

摘要： A double column air separation method in which a first stream of compressed air is cooled by passage through a main heat exchanger from its warm end countercurrently to a nitrogen stream withdrawn from the top of a lower pressure rectification column. The first stream of compressed air flows from the main heat exchanger into a higher pressure rectification column through an inlet. A second stream of compressed air is also passed into the warm end of the main heat exchanger and is cooled therein. The second stream of compressed air passes out of heat exchange with the nitrogen stream at a temperature lower than the exit temperature therefrom of the first stream of compressed air and at least 5K lower than the bubble point temperature of air at the pressure prevailing at the inlet. A stream of oxygen-enriched liquid passes isenthalpically from the bottom of the higher pressure column to the lower pressure column.

摘要： Air is separated in a double rectification column including a lower pressure rectification column. A first oxygen product containing less than 3.5% by volume of argon impurity is withdrawn through an outlet of the column which has a packed section below the level of the outlet. The argon impurity is striped from liquid descending through the packed section and a second relatively pure oxygen product containing less than 100 volumes per million is withdrawn from below the section through an outlet thereof. Impurities less volatile than oxygen are preferably separated from the second oxygen product in a side rectification column.

摘要： Air is separated in an arrangement of rectification columns including a double rectification column for separating oxygen and nitrogen from the air. The double rectification column comprises a higher pressure rectification column and a lower pressure rectification column. There is in addition a side rectification column for separating argon from a stream of argon-enriched oxygen/vapour withdrawn from the lower pressure rectification column. An intermediate pressure rectification column is employed to separate further nitrogen (oxygen-depleted vapour) from the air. An upward flow of vapour through the intermediate pressure rectification column is created by operation of a reboiler to boil liquid in the bottom of the column. In addition a flow of vaporised air is introduced into an intermediate mass transfer region of the column. For example, a stream of liquid air is withdrawn from an intermediate region of the higher pressure rectification column, is vaporised in a condenser and is introduced into the column through an inlet.

摘要： An inflatable life raft incorporates upper and lower canopies that are raised automatically above the upper or lower sides of the raft, respectively, depending on which side of the raft is facing upwardly when the raft is floating. The canopies each form a tent-like enclosure when raised to protect the raft occupants. The canopies are selectively raised by a generally vertically-oriented pillar slideably joined to the raft body, each end of the pillar being joined to corresponding upper and lower canopies. Preferably, the pillar is capable of floating to permit it to elevate above the raft body. The pillar may comprise an inflatable elongate member that slides disposed within an aperture within the floor. A skirt joins the pillar to the floor and provides a reversible waterproof seal between the pillar and the floor and limits the range of vertical travel of the pillar. One or more drain holes may be provided within the base of the skirt to allow the occupants to drain water from within the raft. A fabric cover protects the drain holes, and may be drawn up around the pillar after the water has been drained to prevent water from entering the raft. The raft may also incorporate but a single canopy on one side of the raft, for use in calmer waters where accidental inversion of the raft is unlikely.
