Hydrotreating operations are carried out at different conditions

Hydrotreating operations are carried out at different conditions depending on the type of feed used. However, hydrotreatment generally occurs at very high temperatures and pressure to promote the kinetics of a number of the reactions that occur during this process (Maples 255). For naphtha feeds, the reactor temperature is between 280⁰ and 425⁰C while the pressure is at 200 to 800 (psig). When using gas oil feeds, reactor temperatures are between 340⁰-425⁰C and the pressure is between 800 and 1600 psig (Maples 257). For resid, the operating temperatures are 340⁰-450⁰C while the pressure is between 2000 and 3000 psig.
