PERFORMANCE OF A VENTURI JET SCRUBBER FOR H2S REMOVAL BY IRON-COMPLEX SOLUTION

Venturi jet scrubbers are widely used in chemical industries as an efficient gas-liquid contacting equipment. They are simple in design, have no moving parts, operate with circulating liquid and are reliable in service. Moreover, due to high relative velocity of liquid and gas, considerable overall mass transfer can be produced. In spite of their wide application, readily usable design data are not available in literature, particularly for units producing a gas flow by their own pumping action. The purpose of this paper is to introduce the equipment and its application for H2S removal. The effects of various parameters such as gas and liquid flow rates as well as pressure on hydrodynamics and mass transfer performance of the equipment are investigated. Results of experiments have been shown graphically.
