Abstract

The current investigation aims at studying LPG sweetening process using tertiary alkanolamine (methyldiethanolamine; MDEA) by Aspen HYSYS version 8.0. Design criteria were explained for sweetening LPGs including MDEA concentration, mass flow rate, circulation rate etc. The effects of operating parameters such as temperature and pressure on the proposed process were also studied. A steady state model was developed for determining the sensitivity of parameters affecting the process. The most suited feed LPG temperature was determined to be 45 °C. The optimum MDEA concentration and flow rate was found to be 35.0 wt% and 24.43 m³/h, respectively. The parameters which indirectly affect the extraction process such as reboiler operating pressure, rich MDEA temperature, reflux ratio and boilup ratio were also determined.
