This specification relates to operating industrial facilities, for example, crude oil refining facilities or other industrial facilities that include operating plants that process natural gas or recover natural gas liquids.

A sinusoidal corrugated tube-type spiral wounded heat exchanger suitable for FLNG, wherein a top of an outer cylinder has a shell-side refrigerant inlet and a bottom thereof has a shell-side refrigerant outlet; a sinusoidal corrugated tube-type liquid distributor is below the shell-side refrigerant inlet, a first sinusoidal corrugated winding tube bundle and a second sinusoidal corrugated winding tube bundle, which are heat exchanger tubes with a sinusoidal wave shape, are inside the outer cylinder, and peaks and troughs of the first sinusoidal corrugated winding tube bundle and the second sinusoidal corrugated winding tube bundle are in staggered correspondence one by one from top to bottom; a sinusoidal corrugated tube-type liquid distributor includes a one-into-two-type tube, a two-into-four-type tube, two sinusoidal corrugated tube-type liquid distribution tubes from top to bottom.

A method of constructing a plate fin heat exchanger includes joining a first side bar formed from a nickel-iron alloy to a first end of a fin element formed from a nickel-iron alloy through a first nickel-iron alloy bond, and joining a second side bar formed from a nickel-iron alloy to a second end of the fin element through a second nickel-iron alloy bond to create a first layer of the plate fin heat exchanger. The fin element defines a fluid passage.

The invention relates to a shell and tube heat exchanger (1) having a helical tube bundle (10) within a shell (20), that defines a shell space (200) surrounding the tube bundle (10). The tubes are helically coiled about a core pipe (100) in such a manner that there is formed at least one first section (11) and at least one second section (12), separate from the first section, that surrounds the first section (11). The two sections (11, 12) have in each case at least one associated inlet (E, E′) such that the two sections (11, 12) are able to be charged separately with the first medium.

This specification relates to operating industrial facilities, for example, crude oil refining facilities or other industrial facilities that include operating plants that process natural gas or recover natural gas liquids.

The invention relates to a heat exchanger (1) for indirect heat exchange comprising a tube bundle (10), formed from a plurality of tubes helically coiled around a core tube (100), for receiving a first medium, a shell (20). which encloses the tube bundle (10) and defines a shell space (200) surrounding the tube bundle (10), for receiving a second medium, and a liquid distributor (40) for distributing in the shell space (200) a stream (S), conveyed in the shell space (200), of the second medium in the form of a liquid (F). According to the invention a control device (33) for controlling distribution in the shell space (200) of an additional, further stream (S′) of liquid (F), and/or for controlling distribution of stream (S) of liquid (F) in the shell space (200).

A heat exchanger having multiple plates which are mutually parallel and parallel to a longitudinal direction, the exchanger having a length measured in the longitudinal direction, the plates being stacked with spacing so as to define a first series of passages for the flow, in a general flow direction parallel to the longitudinal direction, of at least a first refrigerant fluid and a second refrigerant fluid, at least one passage of the first series being defined between two adjacent plates.

A heat exchanger includes a core tube extending in a shell space, several tubes wound around the core tube, and a liquid distributor. The liquid distributor is arranged above the tubes in the shell space and applies a liquid phase of a first medium to the tubes. The liquid distributor has distributor arms projecting in the radial direction from the core tube, an annular channel extending above the distributor arms in a circumferential direction of the shell and a collector tank formed by the core tube. The annular channel and the collector tank are each designed to collect the first medium. The distributor arms form at least one first container and at least one second container separated from the first container.

This specification relates to operating industrial facilities, for example, crude oil refining facilities or other industrial facilities that include operating plants that process natural gas or recover natural gas liquids.

An inexpensive heat exchanger is disclosed, wherein the heat exchanger is made up of a plurality of plates and each plate has at least one channel defined in the plate. The plates are stacked and bonded together to form a block having conduits for carrying at least one fluid and where the exchanger includes an expansion device enclosed within the unit. The plates include construction to thermally insulate the sections of the heat exchanger to control the heat flow within the heat exchanger.
