| Abstract | A new heat exchanger design program, SIZEHX, is described. This program allows single step multiparameter cost optimizations on single phase or supercritical exchanger arrays with variable properties and arbitrary fouling for a multitude of matrix configurations and fluids. SIZEHX uses a simplify form on Tinker's method for characterization of shell side performance; the Starling modified BWR equation for thermodynamic properties of hydrocarbons; and transport properties developed by NBS. The report will include results of four parameter cost optimizations on exchangers for specific geothermal applications. The relative mix of capital cost, pumping cost, and brine cost ($/Btu) are determined for geothermal exchangers of the optimal cost distribution for fixed unit costs. |
