ABSTRACT:
From the values for the recycle oil feed rate and the fresh oil feed rate of a hydrocracker a material balance conversion computation is carried out resulting in a material balance conversion signal. From the values for the hydrogen flow rate the temperatures and the pressures thereof and the total oil feed flow rate and the flow rate and temperature of the material leaving the hydrocracker, an enthalpy balance conversion computation is carried out resulting in an enthalpy balance conversion signal. The material balance conversion signal and the enthalpy balance conversion signals are computed into a control signal. The control signal regulates the temperature of the total charge to the hydrocracker to maintain the actual percentage conversion at a desired value.
