Heat transfer and differential pressure in a heat exchanger system at supercritical pressure were investigated. A single dimensional heat transfer model was developed to predict heat transfer rates and temperature profiles in a heat exchanger flowing water near the critical point. A series to trials were performed using test fluids representing produced water over a pH range of 4.0 to 9.0. The temperature profile and differential pressure were measured as the test fluids were heated from 150 °C to 350 °C at 3450 psi (23.8 Mpa) while flowing through the tube side of an experimental concentric tube counterflow heat exchanger. The flow conditions were in the transition region with Reynolds numbers ranging from 4,000-6,000. The test fluid was heated by supercritical de-ionized water flowing through the shell section of the heat exchanger. Seven trials were performed with a duration of 7.5 hours each reporting an average heat flux of 34.22 ± .64 kW/m2. Results showed little to no decrease in heat flux due to fouling. No measureable increase in differential pressure across the heat exchanger was observed during any of the trials.
