Abstract
Psychrometric charts for six different systems involving condensing hy drocarbon vapour in nitrogen are presented The hydrocarbons considered are benzene, toluene, acetone, n-pentane, n-hexane and cyclohexane. T he charts are based upon semi-theoretical equations and make use of pu blished physical property data and correlations. The behaviour of the vapour phase is characterised by the Virial Equation of State truncate d at the third term. The solubility of nitrogen in the liquid hydrocar bons is also considered. The charts are constructed with the dry bulb temperature and absolute humidity scales as the orthogonal axes. Curve s of constant adiabatic saturation temperature, constant relative humi dity, constant gas specific volume and constant enthalpy deviation are plotted on the charts.
