Abstract: Disclosure is made of a counter-current gas-liquid contact apparatus whose shell provided with gas and liquid admission and discharge branch pipes accommodates reflux plates arranged one above another with gaps in between; said reflux plates are made in the form of trays open at the top and assembled into packs; said trays have counter-opposed inclined rims and are arranged on a descending spiral so that there remain passages in the shell between the tray rims and the shell walls for the vertical flow of gas; said passages accommodate horizontal guide baffles which partition completely said passages and deflect the gas flow from one passage into another through the gaps between the trays in the direction from one inclined rim to the other.
