    Flash Open Structure

 

The Flash Open structure allows the following flash calculations and can also be used as a property generator. All calculation options are fully consistent with PVTsim.

The plan is to further develop the Open Structure Architecture to also comprise, allocation software, etc.

Flash Calculation TypeDescription
PT non-aqueous Flash for specified pressure (P) and temperature (T). Considers gas and oil. Water, hydrate inhibitors and salts are not accepted.
PT aqueous Flash for specified pressure (P) and temperature (T). Considers gas, oil and aqueous. Salts are not accepted unless water is present.
PT multi phase Considers gas, oil and aqueous (max 4 phases). Salts are not accepted unless water is present.
K-factor Flash for specified K-factors. Considers gas and oil. No aqueous components are accepted. Pure component fluids are not allowed.
Split-factor Flash for specified Split-factors. Considers gas and oil. No aqueous components are accepted. Pure component fluids are not allowed.
P-Beta Flash for specified pressure (P) and vapor mole fraction (Beta). Beta is the vapor mole fraction of the hydrocarbon phases (i.e. vapor mole fraction not considering aqueous phases). If salt is present, water and at least one non-aqueous component must also be present.
T-Beta Flash for specified temperature (T) and vapor mole fraction (Beta). Beta is the vapor mole fraction of the hydrocarbon phases (i.e. vapor mole fraction not considering aqueous phases). If salt is present, water and at least one non-aqueous component must also be present.
PH Flash for specified pressure (P) and enthalpy (H). Considers gas, oil and aqueous. Salts are not accepted unless water is present.
PS Flash for specified pressure (P) and entropy (S). Considers gas, oil and aqueous. Salts are not accepted unless water is present.
VT Flash for specified molar volume (V) and temperature (T). Considers gas, oil and aqueous. Salts are not accepted.
UV Flash for specified internal energy (U) and molar volume (V). Considers gas, oil and aqueous. Salts are not accepted. Pure component fluids are not accepted.
HS Flash for specified enthalpy (H) and entropy (S). Considers gas, oil and aqueous. Salts are not accepted unless water is present. Pure component fluids are not accepted.
