  • Autoacceleration control for exothermic reactors
    Patent number: 5000924
    Abstract: An autoacceleration control for a catalytic hydrocracker wherein, by means of a model of the reactor, there is generated a signel predicting the reaction temperature and means under the control of the signal adjusting the rate of application of a corrective agent to thereby inhibit auto acceleration of the hydrocracker.

  • Updating physical property correlations with laboratory data
    Patent number: 4847793
    Abstract: A control logic system for updating physical property correlations. The difference between the calculated valve of a physical property and the laboratory value of the physical property is determined and combined with the previously determined value of the difference to obtain a new value of the correlation bias. Actuation of remote switches by the system operator allows this new value of correlation bias to pass through the control system and be "set" until an updated correlation bias is desired by the operator.
