OLI Tips #27The ASAP Variable List
(Revised June 4, 2007)
The following list of variables are used internally in the OLI software. Programs such as the model generator and regression require the use to know these values and the default units.
Variable Name Description Units (Default-Internal)
T temperature Kelvin PT pressure atmospheres I ionic strength mole fraction PH pH --- -IN inflows gmoles -AQ, -ION aqueous solution concentration mole fraction -PPT, - .vH2O precipitates and hydrates g moles H2O water in soln gmoles -SOL solid solution concentration mole fraction </nowiki> Y- vapor mole fractions ---- X-O 2nd liquid phase mole ---- Fractions ---- SOLMAS solid medium mass (for kg cation exchange medium, based upon H-solid molecular weight) LIQMOL total liquid moles gmoles V total vapor moles gmoles SOLSUM total solid moles gmoles TOTO total 2nd liquid moles gmoles ENTHALPY total enthalpy cal ENTHAL liquid phase enthalpy cal ENTHAV vapor phase enthalpy cal ENTHAS solid phases enthalpy cal ENTHAI inert phases enthalpy cal DENLIQ liquid density gmoles/liter ZCOMP vapor compressibility ---- VOL total volume liters VOLLIQ liquid volume liters VOLVAP vapor volume liters VOLSOL solid volume liters EXT kinetics extent of reaction gmoles /hr TSTEP kinetics time step hr A-AQ, A-ION loge (aq phase activity coef) ---- AH2O loge (aq phase H2O activity) ---- AY- loge (vapor phase fugacity coef) ----
Variable Name Description Units (Default-Internal)
