Abstract:
A gas-liquid contact column tray has a section including a gas pathway (SAA) and a liquid pathway section (SD) delimited by at least one downspout, wherein a deflecting system including a roof is included, located above the liquid gas interface at the level of the liquid pathway section (SD), in order to apportion the gas phase over a surface section greater than the section including the means of gas pathway (SAA). In a method for gas-liquid contact in such a column, most of the gas phase part is redirected and apportioned over the whole pathway section available for gas, corresponding to the tray section provided with the gas pathway (SAA), increased by the liquid pathway section (SD), using a deflecting system consisting of the roof located higher than the gas-liquid interface level of the liquid pathway section (SD), and the liquid collected is evacuated toward the lower tray.
