<p>PROBLEM TO BE SOLVED: To treat gas with the fewest possible packing materials without impairment of refining efficiency by passing liquid in a counter current to the gas at an adjustable velocity from the bottom to peak of a column and determining the height of the column in accordance with specific equation at the time of treating the gas. SOLUTION: The column for removing or recovering the components below the half amt. of the gas from the gas has an inlet and outlet port for the gas, an inlet and outlet port for the scrubbing liquid and a fluid packed bed. The gas is passed in the counter current to the gas at the adjustable velocity from the bottom to the peak of the column. At this time, the height of the column is set at the required height in accordance with the height H=k1 .SZ.SH (where, k1 =1.5 to 2.5., SZ is expressed by equation 2 [ye is the molar fraction of the components in the gas in a gas inlet and ya in a gas outlet, y*e is the equil. molar fraction of the components in the liquid at the gas inlet temp. and y*a at the gas outlet temp.] SH is expressed by equation 3 (k2 =1.5 to 2.5.d is the size of the fluid, F is a fluid number, S is a Schmidt number). The column is optimized in such a manner.</p> |
