Abstract
A control system controls the temperature of gas oil being charged to a reactor in a hydrotreating unit. The control system includes a heater which heats the gas oil in accordance with a control signal corresponding to a desired temperature. A gravity analyzer senses the API gravity of the gas oil and provides a corresponding signal. A sulfur analyzer senses the sulfur content of the gas oil and provides a representative signal. A boiling point analyzer senses the 50% boiling point temperature, the initial boiling point temperature and the end point temperature of the gas oil and provides corresponding signals. A flow rate sensor provides a signal corresponding to the flow rate of the gas oil entering the heater. A control signal circuit provides the control signal to the heater in accordance with the signals from the gravity analyzer, the sulfur analyzer, the boiling point analyzer and the flow rate sensor.
