GAS DESORPTION

摘要

The invention relates to a gas desorption unit and a process for desorbing gas absorbed in an absorption liquid, and a gas separation process. A gas desorption unit, comprising an assembly of plates, wherein plates comprise a corrugated part comprising ridges and valleys, and a first channel there between, adapted for counter-current flow of said gaseous and liquid stream in said first channel, and a said second channel for a liquid stream in counter-current flow with the liquid stream in the first channel, wherein a first channel comprises a corrugated part of a first plate comprising ridges crossing with ridges of the corrugated part of a second plate, and wherein a second channel comprises ridges of a corrugated part of a second plate comprising ridges aligned with valleys of a corrugated part of a third plate.

主权项

1. A gas desorption unit comprising an assembly of plates, said assembly comprising a first, second and third plate, each plate comprising a corrugated part comprising ridges and valleys, the corrugated parts of the first and second plate defining a part of a first channel between them, the corrugated parts of the second and third channel defining between them a part of a second channel adjacent to said part of said first channel,
wherein each of the first, second and third plate has opposed lateral ends, wherein the first channel comprises an inlet and an outlet for a gaseous stream at opposed lateral ends and an inlet and an outlet at opposed lateral ends for a liquid stream in counter-current flow with said gaseous stream, and wherein said second channel comprises an inlet and an outlet at opposed lateral ends for a liquid stream in counter-current flow with the liquid stream in the first channel, wherein the first channel comprises a corrugated part of the first plate comprising ridges crossing with ridges of the corrugated part of the second plate, and wherein the second channel comprises ridges of a corrugated part of the second plate comprising ridges aligned with valleys of a corrugated part of the third plate.
