    Abstract: It is known that poorly-flowing solid materials can lead to an inhomogeneous mass flow of the solid across the discharge cross-section of a silo. If the solid in the silo is also heated or cooled the uneven mass flow can lead, for example, to local variations in temperature and/or hence to varying product properties. According to the invention, the above problem may be resolved, whereby a method and a discharge device for a solids silo and a solids silo are disclosed, permitting a controllable solids discharge evenly across the cross-section of the silo. The cross-section of the silo discharge is divided into several, preferably equivalent, partial cross-sections to which a continuously controllable discharge device is connected. The solid flow discharged from the controllable discharge devices can be collected on a continuous conveyor arranged therebelow and removed. The even solid mass discharge from the continuous discharge devices is controlled, depending on measured signals from several equivalent sensors, recording the local mass flow in the corresponding partial sections of the silo, by means of the conveyor power of the discharge device, relating to each sensor. Where electrically-conducting solids are used which are to be heated in the silo using electrodes by means of resistance heating, the control of the discharge devices is achieved with the measured current at the electrodes.

    Abstract: A device is provided for increasing the pH of an acidic aqueous stream, which may result from commercial activity in petroleum, mining, metal finishing and food processing sectors, among others. A container defines an upright reactor portion with a cross-section that increases upwardly, along with inlet and outlet conduits connected to an inlet and an outlet between which the reactor portion is located. The conical portion contains a bed of substantially water-insoluble alkaline salt particulate, such as MgSO, the bed being such that, when the pH of the inflowing aqueous stream is below 7, contact between the particulate and the aqueous stream will raise the pH of the outflowing stream to a level above that of the inflowing stream.

    Abstract: A catalyst withdrawal apparatus and method for regulating catalyst inventory in a fluid catalytic cracking catalyst (FCC) unit is provided. In one embodiment, a catalyst withdrawal apparatus for removing catalyst from a FCC unit includes a pressure vessel having a metering device coupled to a fill port. A heat dissipater is located adjacent the metering device and is adapted to cool catalyst entering the pressure vessel. A sensor is coupled to the pressure vessel arranged to provide a metric indicative of catalyst entering the pressure vessel through the metering device. In another embodiment, a method for regulating catalyst inventory in a FCC unit includes the steps of determining a change of catalyst present in a FCC unit, withdrawing catalyst from the FCC unit into an isolatable storage vessel coupled to the FCC unit, measuring the amount of catalyst disposed in the storage vessel, and removing the measured catalyst from the storage vessel.

    Abstract: A slurry phase reactor is designed to treat extra heavy petroleum crude in a combination of thermal-zone and catalytic-zone in a counterflow system where liquid feed is added to the top and hydrogen at the bottom. Feed enters the gas-phase thermal zone, where it passes to a liquid-phase thermal zone. In the liquid-phase thermal zone, the hydrocarbon is thermally cracked and the unreacted liquid is further passed to a catalytic-zone below in communication with the thermal-zone. Catalyst can be added or removed as required in a continuous mode without shutting down the system. The heat generated inside the catalytic cracking zone is distributed to the entire reactor as the gaseous product flows upward. Feed is brought to the reaction conditions by the heat recovered from the gas-phase zone. Reaction temperature could be controlled by feed temperature.
