GAS-LIQUID CONTACTING APPARATUS

PURPOSE:To decrease the length of ducts connecting with vertical absorbing parts, to reduce the weight of an absorbing tower, and to cut the construction cost by dividing a gas liquid contacting part into two parts for the optimum arrangement, making the length of an absorbing part as short as possible, securing a space to set a gas-gas heat exchanger in the upper parts of the absorbing parts. CONSTITUTION:An apparatus comprises an absorbing liquid tank 12, two vertical absorbing parts 6, 7 placed in the upper part of the tank 12, and vertical ducts 3, 4 connecting respectively with the upper parts of the absorbing parts 6, 7. One of the ducts is an inlet-side duct 3, while the other is an outlet-side duct 4. Two or more nozzles 8, 9 which discharge the absorbing liquid upward are placed in the lower parts of the absorbing parts 6, 7, and a gas-gas heat exchanger 5 is set in the vertical ducts 3, 4. As a result, the length of the absorbing parts is made as short as possible, the ducts connecting to the vertical absorbing parts are made short so that the weight of the absorbing tower can be reduced to curtail the construction cost.
