Aspen simulation fails to remove SO3 from oxygen in water

>->Processing input specifications... Information: There are Henry components defined in this case; the binary database will be searched automatically for any available Henry constants. Parameters specific to certain components are retrieved from the SDF table. These parameters are used with the ELECNRTL option set, unless you enter your own parameters in the PROP-DATA sections. The parameters retrieved for the H2O component are: VLBROC PLXANT parameters. The parameters retrieved for the H2SO4 component are: OMEGA, DHFORM, DGFORM, CPDIEC, DHVLWT, PLXANT, CPIG. The parameters retrieved for the H2SO4 component also include: TC, VC, ZC, MW, RKTZRA. Flowsheet analysis: Calculation order for the flowsheet: ABSORBER -> Calculations begin... The Henry constant model HENRY1 lacks some parameters; please provide those missing parameters for the major solvents. This error may occur because the stream consists entirely of vapor, yet a VLE calculation is requested. Try specifying VALID-PHASES=VAPOR-ONLY. Henry/1st Element (Dataset 1) is missing for the supercritical component O2 when combined with all solvents: SO3. ****Property parameter error: Errors were encountered in calculating the properties of liquid mixtures using the ELECNRTL option set for PHIMX! Calculations were stopped due to missing property parameters
