  • Patent number: 12085334
    Abstract: A method for liquefying a stream of hydrocarbons from a feed stream, including introducing the feed stream and a first cooling stream into a first heat exchanger, extracting a plurality of partial cooling streams obtained from the first cooling stream from the heat exchanger via separate outlets, introducing each partial cooling stream into an expansion element to produce a plurality of biphasic cooling streams at different pressures, introducing each biphasic cooling stream into a phase separator element to produce a gaseous cooling stream which is diverted from the first exchanger and a liquid cooling stream which is introduced into the first exchanger via respective inlets, evaporating each liquid cooling stream by heat exchange with at least the feed stream and the first cooling stream so as to extract a cooled hydrocarbon stream at the outlet from the first heat exchanger and to extract a plurality of evaporated cooling streams.

  • Patent number: 11604024
    Abstract: A process for liquefying a natural gas feed stream including cooling a feed gas stream to obtain a liquefied natural gas stream; introducing the liquefied natural gas stream into a deazotization column to produce a liquefied natural gas stream and a nitrogen-enriched vapor stream; at least partially condensing at least part of the nitrogen-enriched vapor stream to produce a two-phase stream; introducing the two-phase stream into a phase-separating vessel to produce a first liquid stream and a first nitrogen-enriched gas stream; introducing at least part of the nitrogen-enriched gas stream into a distillation column thereby producing a second nitrogen-enriched stream containing less than 1 mol % of methane and a second liquid stream containing less than 10 mol % of nitrogen; wherein at least part of the liquefied natural gas stream is used to cool the at least part of the nitrogen-enriched vapor stream in said heat exchanger.

  • Patent number: 8065835
    Abstract: A device for displaceably holding a glass pane (1) in a sliding rail has at least one fastening part (2) to which a hot-melt adhesive cushion (7) is fitted and which has at least one locking element (10, 11). Furthermore, there is an elongate holding rail (3) which can be brought into engagement with the or each locking element (10, 11). The or each locking element (10, 11) can be moved between a locking position, in which the or each fastening part (2) is connected fixedly to the holding rail (3), and a release position in which the engagement with the holding rail (3) is released and the glass pane (1) can be removed from the holding rail (3). As a result, repair due to wear of the holding rail (3) is less cost-intensive, since the glass pane (1) is connected releasably to the holding rail (3).
