ABSTRACT:
A device for the counter-current contacting of gas and liquid comprises a normally vertical column having a gas inlet and a liquid outlet at the lower end thereof and a gas outlet and a liquid inlet at the upper end thereof. The column contains gas/liquid contacting apparatus located between the gas inlet and the liquid inlet and a gas/liquid separation apparatus located above the gas/liquid contacting apparatus and below the liquid inlet. The separation apparatus includes a horizontal collection tray having passages communication with a separation device and with at least one vertical distribution tube extending through the horizontal collection tray to the gas/liquid separation apparatus. The separation device has a gas outlet communicating to the gas outlet of the column and a liquid outlet, which with the liquid inlet, discharges onto the horizontal collection tray. The device provides gas with a reduced quantity of entrained liquid and is useful for the drying of natural gas by contacting with ethylene glycol.
