Abstract

ONE OF THE MAJOR AND MODERN EQUIPMENTS THAT PLAY A VITAL ROLE IN CHEMICAL ENGINEERING IS BUBBLE COLUMN REACTOR FOR PROMOTING GAS-LIQUID CONTACT. IT IS PARTICULARLY SUITABLE WHERE HIGHER INTERFACIAL AREAS BETWEEN PHASES ARE DESIRABLE AND WHERE ABSOLUTE TEMPERATURE CONTROL IS REQUIRED. THESE ARE GAINING MORE IMPORTANCE RECENTLY BECAUSE OF HIGHER RESIDENCE TIME, HIGHER TRANSFER RATE PER UNIT VOLUME, MINIMUM SPACE REQUIREMENT AND LESS INVESTMENT COST. HERE WE FOCUS THE EFFECT OF VARIOUS PARAMETERS LIKE SUPERFICIAL GAS VELOCITY (VG), HEIGHT TO DIAMETER RATIO (H/D), AND ALSO THE EFFECT OF DIFFERENT ELECTROLYTES LIKE BACL2, MGCL2, NAOH WITH VARIOUS CONCENTRATION ON FRACTIONAL GAS HOLD UP FOR AIR-WATER SYSTEM. THE SPARGER WHICH USED HERE IN THIS COLUMN HAS 20 CIRCLE HOLES WITH 1 MM DIAMETER AS HAS SHOWN IN THE PICTURE.
