A device for distributing a fluid to a processing component includes a vessel having an inlet port for receiving a stream of fluid. A vapor outlet line is in fluid communication with the fluid processing component and has a vapor outlet line inlet in fluid communication with the headspace of the vessel. A liquid outlet line has a liquid outlet line inlet in fluid communication with a liquid side of the vessel and the fluid processing component. A bypass line has a bypass line inlet in fluid communication with the liquid side of the vessel and a bypass line outlet in fluid communication with the vapor outlet line and is configured so that liquid travels through the bypass line and into the vapor outlet line when a liquid level within the vessel reaches a predetermined level so that a headspace is maintained above the liquid level as liquid enters the vessel through the inlet port, and liquid does not travel from the bypass line into the vapor outlet line when a liquid level within the vessel is below the predetermined level.

The invention relates to a heat exchanger for vaporizing a coolant fluid by heat exchange with a calorigenic fluid, said exchanger comprising several parallel plates defining a plurality of passages between them which are suitable for the coolant fluid or calorigenic fluid to flow, a first wave and a second wave extending between two successive plates so as to define a plurality of channels within the same passage, said first and second waves comprising two adjacent edges, at least one assembly member extending from one edge to the other so as to connect the waves to one another. According to the invention, the assembly member is forcibly engaged in at least one part of a channel of the first wave on one hand, and in at least one part of a channel of the second wave on the other hand

A heat exchanger of the brazed plate and fin type, including a plurality of plates arranged in a mutually parallel manner so as to define at least one set of passages for a first fluid configured to exchange heat with at least a second fluid to flow through, the passages extending in a longitudinal direction and a lateral direction perpendicular to said longitudinal direction, each passage being divided, in the longitudinal direction, into at least one distribution zone and one heat-exchange zone, the at least one distribution zone of a passage comprising a distribution element, said distribution element including a plurality of dividing walls arranged so as to divide said distribution zone into a plurality of channels for the first fluid to flow through.

A scraped heat exchanger apparatus, including a vessel and a plurality of internally cooled plates disposed parallel to each other within the vessel. A rotating shaft is disposed at a central axis of the vessel. A rotating scraper arm, connected to the rotating shaft, moves between adjacent plates. The rotating scraper arm includes a scraper positioned to scrape solids from the outer surfaces of adjacent plates. A cooling fluid flows through an interior of each plate. The cooling fluid cools a gaseous process fluid flowing between adjacent plates. An opening in each of the plates permits the process fluid, and solids removed from the process fluid and scraped by the rotating scraper arm, to pass through the plates.

A heat exchanger system includes a core-in-shell heat exchanger and a liquid/gas separator. The liquid/gas separator is configured to receive a liquid/gas mixture and to separate the gas from the liquid. The liquid/gas separator is connected to the core-in-shell heat exchanger via a first line for transmitting gas from the liquid/gas separator to a first region in the core-in-shell heat exchanger and connected to the core-in-shell heat exchanger via a second line for transmitting liquid from the liquid/gas separator to a second region of the core-in-shell heat exchanger

A heat exchanger with plates defining a first series of passages for channeling at least one refrigerant fluid and a second series of passages for channeling at least one calorigenic fluid, at least one passage of the first series being defined between a first plate defining an adjacent passage of the second series and a second plate. A mixing device is arranged in the passage of the first series and includes a first surface arranged facing the first plate and a second surface arranged facing the second plate, at least one first channel for channeling a gas phase of the refrigerant fluid, and at least one second channel for channeling a liquid phase of the refrigerant fluid.

The invention relates to a plate heat exchanger 1 with at least two cuboidal modules 1a, 1b. The two modules 1a and 1b are cuboidal and are each closed to the outside by cover sheets 5. The two modules 1a and 1b are arranged such that in each case, cover sheets 9a and 9b of the same size are directly adjacent. On the contact surfaces, sections 20a, 20b are welded that prevent movement of the two modules 1a, 1b perpendicular to the contact surfaces 9a, 9b either alone or with an additional formed part 50.

A system and method for removing nitrogen and producing a high pressure methane product stream and an NGL product stream from natural gas feed streams where at least 90%, and preferably at least 95%, of the ethane in the feed stream is recovered in the NGL product stream. The system and method of the invention are particularly suitable for use with feed streams in excess of 5 MMSCFD and up to 300 MMSCFD and containing around 5% to 80% nitrogen. The system and method preferably combine use of strategic heat exchange between various process streams with a high pressure rectifier tower and the ability to divert all or a portion of a nitrogen rejection unit feed stream to optionally bypass a nitrogen fractionation column to reduce capital costs and operating expenses.

A method for liquefying a feed gas stream. A compressed first refrigerant stream is cooled and expanded to produce an expanded first refrigerant stream. The feed gas stream is cooled to within a first temperature range by exchanging heat only with the expanded first refrigerant stream to form a liquefied feed gas stream and a warmed first refrigerant stream. A compressed second refrigerant stream is provided is cooled to produce a cooled second refrigerant stream. At least a portion of the cooled second refrigerant stream is further cooled by exchanging heat with the expanded first refrigerant stream, and then is expanded to form an expanded second refrigerant stream. The liquefied feed gas stream is cooled to within a second temperature range by exchanging heat with the expanded second refrigerant stream to form a sub-cooled LNG stream and a first warmed, second refrigerant stream.

A method is disclosed for separating components of a gas. A feed gas stream is cooled in the first vessel. The feed gas stream comprises methane, carbon dioxide, and a secondary component. A first portion of the secondary component condenses, desublimates, or a combination thereof to form a primary stream, resulting in a first depleted gas stream. The first depleted gas stream is cooled in a condensing exchanger such that a first portion of the methane condenses as a first liquid methane stream, resulting in a second depleted gas stream. The second depleted gas stream is cooled in the second vessel such that a first portion of the carbon dioxide desublimates to form a solid product stream, resulting in a third depleted gas stream.
