The new features and fixes are: 1. Added Peng-Robinson binary interactions parameters (BIPs) for a number of hydrocarbon pairs. Methane-hexane, -heptane, -octane, -nonane, and -decane BIPs were created. 2. Added a small negative Peng-Robinson BIP to most of the hydrocarbons C3-C10 with nonane and decane 3. Added several new properties for Al(OH)3, component #1535 4. Added Refrigerant 1234yf to the database as component #1539 5. Added calculation of vapor densities by component to the vapor density calculation method. The detailed stream actual volumetric component flowrates table now use these densities instead of the average vapor density for the vapor phase. 6. Added a stream validation rule for specified streams that if the general thermodynamic rule is GERG 2008 or the stream specific thermo is GERG 2008 then pure components not in the GERG 2008 thermodynamic method must have zero flowrates. 7.
