Abstract: A heat exchanger unit that comprises a heat exchanger vessel comprising a plurality of process stream conduits to receive the gaseous process stream and discharge a cooled process stream, and a plurality of refrigerant conduits to receive a pre-cooled mixed refrigerant stream and discharge a cooled mixed refrigerant stream; an expansion device to receive the cooled mixed refrigerant stream and discharge a further cooled mixed refrigerant stream, which is connected to a third and/or fourth refrigerant inlets to provide cooling to the process stream conduits and the refrigerant conduits; a refrigerant bleed vessel to receive a first refrigerant split-off stream from the cooled mixed refrigerant stream and a second refrigerant split-off stream from the pre-cooled mixed refrigerant stream; the refrigerant bleed vessel comprising a bleed outlet to discharge a bleed stream and a recycle outlet fluidly connected to the third and/or fourth refrigerant inlets.

Abstract: The present disclosure provides a heat axchanger and heat exchange method for cooling a gaseous process stream.

Abstract: The invention relates to a method for the absorption of acid gases, such as CO2 and H2S, from gas mixtures. According to the invention, acid gases are absorbed from a gas mixture by contacting this gas mixture with a liquid in which is dissolved so high a concentration of an amino acid or a salt thereof that a precipitate is formed. The contact takes place in a column of the packing-free type or a column suitable for processing slurries.

Abstract: The present invention relates to a method of treating a hydrocarbon stream such as a natural gas stream, the method at least comprising the steps of: (a) supplying a partially condensed feed stream (10) to a first gas/liquid separator (2), the feed stream (10) having a pressure >50 bar; (b) separating the feed stream (10) in the first gas/liquid separator (2) into a first vaporous stream (20) and a first liquid stream (70); (c) expanding the first vaporous stream (20), thereby obtaining an at least partially condensed first vaporous stream (30); (d) supplying the at least partially condensed first vaporous stream (30) to a second gas/liquid separator (4); (e) separating the stream (30) as supplied in step (d) in the second gas/liquid separator (4) into a second vaporous stream (60) and a second liquid stream (40); (f) increasing the pressure of the second liquid stream (40) to a pressure of at least 50 bar, thereby obtaining a pressurized second liquid stream (50); and (g) returning the pressurized second

Abstract: The present invention relates to a method of deriching a stream of liquefied natural gas by extracting a natural gas liquid comprising inter alia the steps of: heating the stream of liquefied natural gas (1) in a first heat exchanger arrangement (5); splitting it into at least a first portion (17) and a second portion (19); passing the first portion (17) to a distillation column (21) and passing the second portion (19) to a second heat exchanger arrangement (26) and then supplying it (20) to the distillation column (21) from which a natural gas liquid stream (35) and an overhead vapour stream (40) are withdrawn; —passing the overhead vapour stream (40) to the second heat exchanger arrangement (26) to form an intermediate deriched condensate stream (49) of which at least a portion is thereafter passed to the distillation column.
