Device for the exchange of heat between a first fluid intended to be vaporized and a second fluid intended to be cooled and/or condensed, and associated installation and method

A device for the exchange of heat between a first fluid intended to be vaporized and a second fluid intended to be at least one of cooled or condensed, comprising:

• a shell defining an interior volume to receive the first fluid extending along a longitudinal axis;
• a tube bundle arranged inside the shell, the tube bundle extending longitudinally in the interior volume to receive the second fluid;
• a disengagement member, able to perform liquid vapor separation in the fluid carried from the interior volume, the disengagement member being arranged above the tube bundle, the disengagement member being arranged inside the interior volume defined by said shell;
• wherein, in at least one same plane perpendicular to the longitudinal axis, the disengagement member includes at least a first horizontal fluid passage region of the fluid carried from the interior volume, a second horizontal fluid passage region of the fluid carried from the interior volume and a third horizontal fluid region of the fluid carried from the interior volume which are separate, the disengagement member further comprising at least a first intermediate region preventing fluid carried from the interior volume from passing and a second intermediate region preventing fluid carried from the interior volume from passing,
• wherein the first horizontal fluid passage region is defined by a first horizontal open-worked partition wall, the second horizontal fluid passage region is defined by a second horizontal open-worked partition wall, and the third horizontal fluid passage region is defined by a third horizontal open-worked partition wall, the first horizontal open-worked partition wall, the second open-worked partition wall and the third open-worked partition wall each extending horizontally in said same plane perpendicular to the longitudinal axis,
• wherein, each of said first horizontal open-worked partition wall, second horizontal open-worked partition wall and third horizontal open-worked partition wall includes a plurality of through-openings,
• wherein the first intermediate region is formed by a first tilted solid wall connecting the first horizontal open-worked partition wall and the second horizontal open-worked partition wall and the second intermediate region is formed by a second tilted solid wall connecting the second horizontal open-worked partition wall and the third horizontal open-worked partition wall,
• wherein, in said same plane perpendicular to the longitudinal axis, the first horizontal open-worked partition wall and the third horizontal open-worked partition wall are located at a first height and the second open-worked partition wall is located at a second height above the first height,
• wherein, in said same plane perpendicular to the longitudinal axis, the first horizontal open-worked partition wall and the third open-worked partition wall region define an intermediate space between them, the second horizontal open-worked partition wall covering the intermediate space, and
• wherein, in said same plane perpendicular to the longitudinal axis, a width of the second horizontal open-worked partition wall is greater than a width of the intermediate space.
