Abstract
Abstract 922,015. Contacting a gas with a liquid. F. L. YERZLEY. July 7, 1960 [July 7, 1959], No. 23756/60. Class 55 (2). In a method of contacting a gas with a liquid the gas is passed upwardly and the liquid downwardly through a bed of discrete aggregate particles and the area of the bottom surface of the bed exposed to gas flow is varied such that the bed is in use floded with liquid. The aggregate is supported on a foraminous plate and the desired portion of the surface area thereof may be closed to the flow of gas by transverse baffles or by suitably arranged plates. The support shown in Fig. 7 comprises a foraminous screen 20A, stationary sector-shaped strips 49 and sector-shaped strips 48 rotatably mounted on a shaft 50 rotatable from a position outside the chamber containing the bed of aggregate. In a modification shown in Fig. 9 elements 54 secured to rotatable rods 56 can be moved to vary the lipped area of a foraminous screen 52. Two or more beds of aggregate may be arranged one above the other and the gas and/or liquid flowing from one bed may be caused to move laterally before passing through a second bed. The aggregate may be crushed stone or marble chips and the beds 6 inches high.

A METHOD OF PRODUCING INTIMATE CONTACT BETWEEN A LIQUID AND GAS IN COUNTER-CURRENT FLOW COMPRISING, MAINTAINING ON AN OPEN MESH SUPPORT HAVING A NORMALLY OPEN AREA FOR THE FLOW OF FLUID THERETHROUGH A BED OF DISCRETE AGGREGATE PARTICLES WITH OPEN EXPOSED TOP AND BOTTOM SURFACES, FLOWING LIQUID ONTO THE SAID TOP SURFACE FOR DOWN FLOW BY GRAVITY THROUGH SAID BED AND NORMALLY OPEN AREA OF THE SUPPORT AT A PREDETERMINED RATE, EXHAUSTING GAS FROM THE REGION ABOVE SAID TOP SURFACE TO INDUCE AN UPWARD FLOW OF GAS FROM BELOW SAID SUPPORT THROUGH SAID NORMALLY OPEN AREA AND THROUGH SAID BED AT A RATE SUFFICIENT TO BALANCE THE SAID RATE OF FLOW OF THE DOWNWARDLY FLOWING LIQUID THEREBY TO CAUSE THE LIQUID TO SUBSTANTIALLY COMPLETELY FILL THE SPACE BETWEEN THE AGGREGATE PARTICLES AND CAUSE A FLOODING OF THE BED, AND THE MAINTENANCE THEREOF IN FLOODED CONDITION DURING NORMAL OPERATION SOLELY BY THE UPWARDLY FLOWING GAS, MAINTAINING IN A COMPLETELY OBSTRUCTED CONDITION A PLURALITY OF IMMEDIATELY ADJACENT OPENINGS TOGETHER CONSITITUTING A LIMITED PORTION O OF THE NORMALLY OPEN AREA OF SAID SUPPORT TO PREVENT THE FLOW OF LIQUID AND GAS THROUGH THE OPENINGS CONSTITUTING SAID LIMITED PORTION AND LEAVING THE OPENINGS CONSTITUTING THE REMAINDER OF SAID NORMALLY OPEN ARA COMPLETELY UNOBSTRUCTED FOR THE FREE FLOW OF LIQUID AND GAS THERETHROUGH THEREBY TO CAUSE THE LIQUID AND GAS CONTACTING THE OBSTRUCTED LIMITED PORTION OF THE NORMALLY OPEN AREA TO FLOW LATERALLY OF THE PORTION OF THE SUPPORT INCLUDING THE OBSTRUCTED OPENINGS TOWARD THE UNOBSTRUCTED OPENINGS WHEREBY THE PORTION OF THE LIQUID FLOWING THROUGH THE BED AND CONTACTING THE PORTION OF THE SUPPORT INCLUDING THE OBSTRUCTED OPENINGS FLOWS LATERALLY OF THE SUPPORT AND DOWNWARDLY THROUGH THE UNOBSTRUCTED OPENINGS TOGETHER WITH THE REMAINDER OF THE LIQUID, AND THE GAS CONTACTING THE PORTION OF THE SUPPORT INCLUDING THE OBSTRUCTED OPENINGS FLOWS FIRST LATERALLY BELOW THE SUPPORT THEN UPWARDLY TOGETHER WITH THE REMAINDER OF THE GAS THROUGH THE UNOBSTRUCTED OPENINGS, AND THE GAS DIFFUSES LATERALLY AND FLOWS UPWARDLY SUBSTANTIALLY THROUGH OUT THE ENTIRE BED SO THAT THE CAPACITY OF THE BED IS NOT MATERAILLY AFFECTED BY THE OBSTRUCTING OF THE OPENINGS CONSTITUTING A LIMITED PORTION OF THE NORMALLY OPEN AREA OF THE SUPPORT, THE SAID REMAINDER OF THE NORMALLY OPEN AREA CONSTITUTED BY THE UNOBSTRUCTED OPENINGS BEING OF A SUFFICIET EXTENT SO THAT ALL OF THE LIQUID FLOWS THROUGH THE BED AND SUPPORT AND NO ACCUMULATION OF LIQUID TAKES PLACE WHEN THE DOWNWARD FLOW OF LIQUID IS CONTINUED AT SAID PREDETERMINED RATE AND THE UPWARD FLOW OF GAS IS DISCONTINUED.
