Abstract

This work has been carried out to investigate the effects of fresh water volumetric flow rate, column tray number, wastewater feed tray number and boil-up ratio on the stripping column used for the purification of wastewater containing hydrogen sulphide as the main impurity. The stripping column was modelled with the aid of Aspen HYSYS using Electrolyte NRTL as the Fluid Package. The wastewater feed and the stripping liquid (fresh water) feed were passed into the stripping column at a temperature of 25oC and a pressure of 1 atm. From the results obtained from the investigations carried out, it was revealed that pure water was obtained as the bottom product of the stripping column used for the purification of the wastewater but the mass fractions of the hydrogen sulphide and the purified water in the top product were found to vary with the changes in the parameters considered. So, it is recommended that the values of the parameters should be chosen for the treatment of the wastewater containing hydrogen sulphide based on whether hydrogen sulphide is expected to be in low or high concentration in the top product of the column.
