A Review Paper on Heat exchangers used for PROX reactor

Abstract

The PROX reaction process occurring in the reactor with 1%(wt) platinum based on iron hydroxyphosphate
was analyzed between temperature range of 80 0C and 120 0C in hysys software. A shell and tube type heat exchanger
was designed and analyzed for temperature control for PROX reaction, containing copper tubes. The temperature profile
suggests the expected temperature rise in the PROX reactor and temperature drop in the heat exchanger. The heat
exchanger was able to bring down the temperature of gases from 210 oC to 113 oC successfully. The gas composition sent
to the PROX reaction process was 40% H2, 1% CO, 9% CO2, 0.5% O2, and 49.5% Ar. The result suggests that the
removal of heat from the gases increases the CO selectivity and conversion.
