  • Solid addition and withdrawal
    Patent number: 5021147
    Abstract: A system for adding and withdrawing solids to a high pressure reactor wherein there is provided improved control of flow and concentrations of a slurry of solids in a transport oil for introducing and withdrawing solids from the reactor. In addition, there is provided for improved heating and cooling of the solids.
    Type: Grant
    Filed: June 7, 1989
    Date of Patent: June 4, 1991

  • Temperature control for hydrogenation reactions
    Patent number: 4707245
    Abstract: Temperature is controlled in a hydrogenation reactor without changing the flow rate of feed into the reactor to maintain a pre-determined temperature in the reactor. In one embodiment, the firing rate of a fuel fired furnace for heating feed to the reactor is controlled in response to the temperature sensed in the reactor to maintain a pre-determined temperature. In another embodiment, the flow rate of a quenching stream for cooling feed to the reactor is controlled in response to temperature sensed in the reactor to maintain a pre-determined temperature in the reactor.

  • Control of bed expansion in expanded bed reactor
    Patent number: 4684456
    Abstract: In an expanded bed reactor, the expansion of the bed is automatically controlled by automatically changing the rate of speed of a recycle pump for the reactor. The bed is preferably provided with both high and low level bed detectors, and a further detector for determining abnormally high levels.
