Effect of Variation in LPG Composition on Heating Value Using Aspen HYSYS

Md. Saiful Alam, Istiak Hussain


Liquefied petroleum gas (LPG) is becoming an increasingly important part of the world’s energy sources. The determination of the heating value of LPG is of great economic importance in domestic and industrial purposes. This paper discusses the effects of impurities (e.g., moisture, H2S) and the presence of other hydrocarbons (e.g., ethane, pentane, propene, and butene) on the heating value of LPG fuel with different propane to butane. Different LPG composition (propane:butane) of 80:20, 60:40, 40:60, and 20:80 are used in this study. In addition, comparative studies of two mercaptans used as leakage identifiers and two inhibitors used for hydrate formation reduction are examined. Aspen-HYSYS process simulator is used to determine the heating value.
