Title: Analysis of direct contact binary cycles for geothermal power generation (program DIRGEO)

Abstract

A computer program was produced which would analyze a direct-contact binary fluid power plant as conceived for geothermal applications. The current cycle consists of a direct-contact boiler, binary vapor mixture turbine, parallel flow liquid-liquid preheaters, pumps, flash expander and a condenser. The program computes important design parameters which allow the user to select the optimum operating condition for a particular well. The program allows for the evaluation of cycles utilizing liquid hydrocarbons and fluorocarbons as secondary fluids. A complete description of the executive program including flow charts, program listings and variable symbol tables is contained. A sample run of the main program completes the description of its use.
