摘要： A fluid is cooled and liquefied in an apparatus with a heat exchanger. A plurality of flow passages has two or more primary groups of one or more primary flow passages. Each primary group carries a part of the fluid stream through the heat exchanger and indirectly cools the part of the fluid stream against a refrigerant in the shell side of the heat exchanger to provide a liquefied fluid stream. A primary inlet header connects the two or more primary groups of primary flow passages to a source of the fluid, and is arranged to split the fluid stream between the two or more primary groups of primary flow passages. Valves are provided for selectively blocking at least one of the two or more primary groups of primary flow passages whilst allowing the fluid stream to flow through the remaining unblocked primary groups of primary flow passages.

摘要： 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.

摘要： A method for integrating a liquefied natural gas liquefier system with production of liquefied natural gas from a methane-containing gas stream. The liquefied natural gas is produced by feeding a methane-containing gas stream through a heat exchanger to a distillation column and liquefying the natural gas while capturing the gaseous nitrogen. The liquefied natural gas is captured and the nitrogen gas is recovered, fed through the heat exchanger to recover cold and purified.

摘要： The present invention relates to a method and apparatus for producing a pressurized product stream product by cryogenic rectification. A main heat exchanger, used in the cryogenic rectification, warms a pumped product stream composed of oxygen-rich or nitrogen-rich liquid and thereby produces the pressurized product stream. Layers of the main heat exchanger are designed such that a reduction in the heat transfer area provided within the main heat exchanger for warming the pumped product stream occurs at a location at which the temperature of the pumped product stream exceeds either the critical or a dew point temperature of such stream. The reduction in heat transfer area leaves regions of the layers able to heat or cool another stream that is used in connection with the cryogenic rectification. Such other stream can be a refrigerant stream that allows the introduction of additional refrigeration to increase production of liquid products.
