Overall Aspen HYSYS model

Next we specify the flow rates, yields and composition of all the key streams from the reformer. A compositional analysis is necessary to make sure that we model key reaction paths accurately. We recommend that users enter all compositional information for gas streams in mol% and aU compositional information for liquid streams in vol.% or wt.%. Given the data available, we can enter the flow rates of each steam on a gas flow or mass flow basis. We note that internally. Aspen HYSYS will convert all measurements into a mol% to ensure overall material balance in the model results.
