Minimum XFlow file requirement

For the XFlowLoader to successfully populate a stream, at least the properties "Flow Rate" and "Composition" or the property "Compound Flow Rate" is required in the XFlow file in either mole or mass basis. Absence of the "Flow Rate" and "Composition" properties in favour of the "Compound Flow Rate" is only supported if the total flow rate is non-zero.

The composition and compound flow rate maps to compounds, which need to map to the compounds that are present in the stream to be populated. For the compound mapping to be set up, the XFlow file must at least contain the compounds, and for each compound a compound ID.

In addition, the phase equilibrium must be calculated on the product stream. For the TP flash, the XFlow file must contain "Pressure" and "Temperature". For the P-VF flash, the XFlow file must contain "Pressure" and either "Vapor Fraction" for the overall phase, or "Phase Fraction" for the phases. For the PH flash, the XFlow file must contain "Pressure", as well as the reference state corrected enthalpy, reference state phase name, reference state phase state of aggregation, reference temperature and reference pressure for adjusting the corrected enthalpy to meet the enthalpy of the target thermodynamics. These enthalpy options are saved by the XFlowSaver unit operation if the Write Enthalpy option is enabled.
