Embodiment Construction

[0053] figure 1 and figure 2 Shown is a heat exchanger 1 for forming a not shown gas separation unit based on heat transfer from at least one primary fluid, called heat generating fluid, to at least one secondary fluid, called coolant.

[0054] The heat exchanger 1 comprises a plurality of plates 2 . Known per se, the plates 2 are arranged parallel to each other. The plates 2 define channels (not shown) configured for the flow of heat generating fluid or coolant.

[0055] figure 1 and figure 2 In the embodiment, each plate 2 is in the form of a rectangle as a whole. The heat exchanger 1 is in the form of a cuboid as a whole. The heat exchanger 1 here has a length of about 6m, a width of about 2m, and a height of about 2m.

[0056] By convention, the length of the heat exchanger is measured parallel to the direction of coolant flow in the channels, and the width of the heat exchanger is measured perpendicular to the length. The height of a heat exchanger is measured a...

Abstract

The invention relates to a heat exchanger (1) comprising: parallel plates (2) defining channels for heating or cooling fluids, spacers extending between the plates (2) and defining channels, and an individual casing covering the plates (2) and comprising a fireproof heat insulation layer.

Description

technical field [0001] The present invention relates to heat exchangers for forming gas separation units by heat transfer from at least one primary fluid, called heat generating fluid, to at least one secondary fluid, called coolant. Furthermore, the invention also relates to an installation method for installing a cryogenically based gas separation unit comprising at least two of said heat exchangers. [0002] The invention finds particular application in the field of gas separations based on cryogenic temperatures. In particular, the invention finds use in the field of cryogenic separation of air. Background technique [0003] FR2844040A1 describes a heat exchanger assembly comprising two heat exchangers. Each heat exchanger includes plates parallel to each other defining fluid passages and spacers defining passages. Additionally, the heat exchanger assembly includes input and output tanks connecting each heat exchanger with the primary and secondary manifolds. [0004...
