MASS TRANSFER PROCESS OF GASEOUS CARBON DIOXIDE INTO AQUEOUS WATER JET THROUGH JUNCTION PIPES

摘要

This paper summarizes the mass transfer modeling that can simulate the gaseous CO{sub}2 dissolution into the liquid water. Using the model, numerous computations have been performed for four different designs of the junction-type of Venturi-tube. The computed results show different performance of the carbon dissolution rates for the given inlet water and CO{sub}2 conditions of the four different designs of the junction Venturi-tube. After examining the computed results it was found that the design of Venturi with converging nozzle attached at the inlet of the tube seems to perform better than other designs in order for CO{sub}2 gas to uniformly dissolve into the liquid water stream.
