SEVERE ERROR IN PHYSICAL PROPERTY SYSTEM
      HENRY CONSTANT MODEL HENRY1 HAS MISSING PARAMETERS. PLEASE
      PROVIDE THE MISSING PARAMETERS FOR MAJOR SOLVENTS. THIS ERROR MAY OCCUR
      BECAUSE THE STREAM IS ALL VAPOR, BUT VLE CALCULATION IS REQUESTED.
      TRY SPECIFY VALID-PHASES=VAPOR-ONLY
      HENRY/1ST ELEMENT (DATA SET 1) MISSING FOR SUPERCRITICAL COMPONENT
      NH4OH WITH ALL SOLVENTS:
