CONTACT AND SEPARATION COLUMN AND TRAY

摘要

A contact and separation column (1) encasing a stack of one or more contact and separation cells (3). Each cell comprises: - a tray (4) with gas flow openings (6) opening into contact and separation units (7); - a downcomer (16) defining a liquid discharge; and - a liquid supply (17). Each contact and separation unit (7) comprises an upstream contact zone (8, 9) with liquid inlets (12), and one or more downstream separation zones (10) provided with a swirler (13) and a top end with a gas outlet (14). The swirler (13) is located at a distance from the gas inlet of from 50 to 90 % of the total length of the contact and separation zone. Process for treating a gas with such a column.
