Multiphase system online property prediction

Pure component vapour pressures of organic compounds

Calculate the sub-cooled liquid vapour pressure of organic compounds using group contribution methods. All group contribution techniques parse the entered compound, currently represented by a SMILES string, into specific functional groups according to a SMARTS library. These functional group combinations are then combined with 'interaction' parameters and/or physical parameters to arrive at a given property estimate according to the underlying equations. The methods provided were reivewed by Barley and McFiggans 2010 and O'Meara et al 2015
