Customization and validation of a commercial process simulator for dynamic simulation of Helium liquefier

Dynamic simulation of helium plants using Aspen Hysys ®, V7.0 has been validated using cool-down temperature data from two existing helium plants under operation. Fluid properties of helium using 32-term MBWR EOS are found to be numerically unstable and Hepak ® data has been fed as a table. Metal pr...
