8A.Hydrocarbon Liquid Enthalpy using the Charts in Appendix 8A. Back to Main
This page it used to determine hydrocarbon liquid enthalpy using the chart in Appendix 8A. Values are plotted for liquid molecular weights from 30 - 100. Above this range other correlations are advised. Below this range one is looking at methane - ethane liquid for which this correlation is not suitable.
Enthalpy is a quantity defined by the relationship H = E + PV. The enthalpy change, DH, for a reaction that occurs at constant pressure in the heat evolved or absorbed in the reaction.
To carry out the enthalpy calculation the Temperature and Molecular Weight of the liquid must be entered into the entry space. To do so use the mouse to click the courser in the entry spaces and input the data.
Once Temperature and Molecular Weight of the liquid has been entered, select Run to execute the solution.
