Desorption of Dissolved Carbon Dioxide From Water Using Converging Nozzle : Effect of Temperature

The demands on natural gas keep increasing for the last several years. However,
most of the world’s reserves natural gas contain high amount of carbon dioxide. It is crucial
to change current desorption technique with new compact size separator that can remove
carbon dioxide instantly and feasible to be used at offshore platform. This project aims to
investigate effect of temperature towards desorption of carbon dioxide from the solvent by
using converging nozzle and how effectiveness of physical desorption of carbon dioxide
change with temperature. This research covered concept of gas-liquid desorption,
solubility of carbon dioxide, vapour liquid equilibrium, supersaturated ratio, effect of
temperature towards desorption and effectiveness of the converging nozzle used.
Laboratory work is done using special test rig. To convey effect of temperature, test was
run at different temperature will other parameters kept constant (pressure,
