Embodiment Construction

[0024] image 3 The cross-section of the regeneration column at the level at which the gas-laden liquid stream is introduced is schematically shown. The housing at the top of the regeneration tower, indicated at 1, is provided with a radial inlet pipe 3 which transitions into the first bend 2 immediately after entering the tower. A flange may be provided at the point where the inlet pipe 3 enters the tower, by means of which flange the elbow structure according to the invention is coupled to the inlet pipe 3 . image 3 The bend 2 shown has a bending angle γ of 45° and joins a straight pipe piece 7 which transitions into a second bend 4 bent in the opposite direction. The second bend likewise has a bending angle (γ′) of 45°. The length of the straight pipe fitting 7 is image 3 In the case shown, the second elbow is chosen such that it is offset by approximately 90° relative to the inlet nozzle 3 on the arc defining the inner circumference of the column. The outflow 5 of th...

Abstract

The invention relates to a device for the tangential introduction of a gas-loaded liquid stream into the head of a column in which gas and liquid are separated. Entry into the column head proceeds via a conventional radially arranged port (3) to which is connected, however, a special tube construction (2, 7, 4) which ensures as smooth and vortex-free a flow as possible and tangential discharge thereof into the column head.

Description

technical field [0001] The invention relates to a device for introducing a gas-laden liquid stream tangentially into the top of a column in which gas and liquid are separated, wherein the top of the column is entered through a generally radially arranged connecting piece connected to a The special tube construction ensures the smoothest possible flow without swirls and tangential discharge into the top of the column. Background technique [0002] In many chemical industrial processes there are acid gases such as CO contained as impurities 2 、H 2 S, SO 2 、CS 2 , HCN, COS or gas streams of mercaptans. These gas streams may be, for example, natural gas, synthesis gas from heavy oils or residues, refinery gases or reaction gases produced when organic materials such as coal or petroleum are partially oxidized. Before these gases can be transported or further processed, the acid gas content of the gases must be significantly reduced. For example CO must be removed from natur...
