Efficiency Modeling of Rotary Degasser Head Configurations and Gas Introduction Methods, Part I - Water Tank Tests

摘要

The use of ceramic materials for rotary degasser heads and shafts is on the increase and a wide variety of head designs and methods of gas introduction (e.g. holes versus porous medium) are now available. This paper attempts to rank the efficiency of various head designs and gas introduction methods by measuring the removal of dissolved oxygen from water at room temperature. Several rotor head designs and gas introduction configurations were tested under a variety gas flow rates and rotational speeds to determine the rates of oxygen removal and the ultimate residual oxygen levels.
