Industrial Direct Heat Plant, Resource and Heat Plant Modelling

Abstract

INDUSTRIAL DIRECT HEAT PLANT. RESOURCE & HEAT PLANT MODELLING A numerical model has been developed to assist the feasibility review of industrial direct heat use geothermal systems. The model allows all major components in the system to be simulated. Supply and reinjection well models and piping distribution systems can be evaluated to optimise sizing and maximize potential well outputs. With knowledge of the application’s heat requirements, the plant temperature, pressures and energy flows can be matched with the geothermal resource. Applications are possible for both heating of secondary fluids using two phase or separated geothermal flows as well as direct geothermal steam applications. The model includes budget costing parameters and allows rapid analysis for feasibility purposes. System flexibility allows sensitivity analysis for varying well performances and end use variations.
