WitrynaThe naphtha hydro treating unit uses a cobalt-molybdenum catalyst to remove sulfur by converting it to hydrogen sulfide that is removed along with unreacted hydrogen. Reactor conditions for a naphtha hydrotreater unit are around 400-500˚F (205-260˚C) with a pressure of 350-650 psi (25-45 bar). A two-wire style HART pressure transmitter is ... WitrynaThe heat of the reactor effluents was being utilised to preheat the unit feed to heater inlet temperature. In the present case, the reaction temperature was reduced from 315°C to 290°C. This substantially reduced the reactor effluent temperature. Hence, the feed preheat was also substantially reduced by 15-25°C. capability test cpk
