COMPUTER DRAWING OF ENTHALPY-HUMIDITY CHARTS

Abstract

Enthalpy-humidity charts for a gas-vapour mixture still provide a fast and easy tool for use in process culculations in drying, solvent recovery and related processes. They have to be individually constructed for each new system encountered. The computer graph-plotting method provides a fast and reliuble way of enthalpy-humidity chart production. Theoretical principles of computerized i-Y chart plotting are provided. Exemplary charts for systems of nitrogen and benzene, n-heptane, and cyclohexane are given.
