How to enter the ethnic composition data in ASPEN?
Thread Content
Please tell me how to input the ethnic composition data in ASPEN? Because there are no specific substances in the analysis of group composition, it only has the volume percentage of alkanes, cycloalkanes, alkenes, and aromatic hydrocarbons such as C3, C4, C5, C6, C7, C8, etc. How do I enter it in the simulation? For example: C8 aromatics include o-xylene, p-xylene, and m-xylene. In the family analysis, there is only the content of C8 aromatics, but there is no specific substance content.

Generally, you can enter the component molecular formula according to saturated n-alkane.
Can it be defined as a substance with nonconventional components? What I do is gasification of biomass. The group analysis of biomass is composed of many kinds of substances, which is unconventional. Then the parameters of density and entropy required to calculate the density and entropy of this substance are defined in the pure component of the parameter. But mine may be different from yours
It cannot be input, and it cannot be calculated after input. Think about it, what is the significance of inputting a C2-C8 alkane component without knowing its distillation range split composition? How to calculate it? , cannot represent a physical property unit.
You can enter a representative substance representation. For example, C8 aromatic hydrocarbons are represented by p-xylene. It is a little troublesome, but it is doable. . .
