The Hydro-Thermal Corp. online calculator uses thermodynamic assumptions and formulas to estimate the energy used for specific process conditions and compares the required energy of a heat exchanger with that of a direct steam injection three-way valve. Users can input their process flow rates, needed output temperature, fuel costs and other data directly into the calculator.
