摘要：This paper aims to analyze the thermal performance of four different heat transfer fluids in a hot oil system located in a paraffin hydrotreatment and fractionation plant of a petroleum refinery. The software Petro-SIM? (KBC-Yokogawa) was employed to elaborate steady-state simulations intended to compare the heat transfer fluid currently used (eutectic of biphenyl and diphenyl oxide) and three fluids proposed as substitutes: paraffin oil (namely n-C13 ) produced in the very industrial unit, a nanofluid of eutectic of biphenyl and diphenyl oxide and copper at a 6 % volume fraction, and a CuO/polydimethylsiloxane nanofluid at a 6 % volume fraction. The results showed that n-C13 was the only heat transfer fluid that could replace the eutectic diphenyl oxide/ biphenyl in the system under analysis since it absorbed the heat duty of 13.79 Gcal/ h, which exceeded the thermal energy of 10.57 Gcal/ h absorbed by the heat transfer fluid currently used at the same operating parameters. The Cu/ eutectic of biphenyl and diphenyl oxide and CuO/polydimethylsiloxane nanofluids presented lower heat duty than the energy needed for the operation of the hot oil system, which was 8.31 Gcal/h and 8.51 Gcal/h, respectively.
