A method for separating catalyst particles from the FCC slurry oil present in the retentate of a filtered FCC slurry oil run-down stream is disclosed. The method comprises backwashing the run-down stream filter with a low boiling point solvent to extract slurry oil from the catalyst in the retentate. The backwash solution is sent to a digester where the catalyst fines are separated from the hydrocarbon component (solvent and slurry oil). The catalyst fines are collected and dried. The dried catalyst fines can be transported via pneumatic systems, and can be regenerated for further use as FCC catalysts. The solvent vapor from the drying process is collected for potential reuse. The hydrocarbon component is sent from the digester to an evaporator to evaporate the solvent from the slurry oil. The FCC slurry oil and the solvent exiting the evaporator can be independently collected. The solvent from the evaporator can be reused in the process. 1.

Nuclear reactor using controlled debris to mitigate eccs strainer pressure head loss

Номер: US20190221323A1
Принадлежит: Continuum Dynamics Inc

Controlled-debris elements inhibit the formation of a fibrous/particulate debris bed that unduly increases the pressure head loss through the perforated plates of strainers in a nuclear power plant emergency core cooling system. In a loss of cooling accident, pumps draw cooling water through the plates, which retain on their surfaces fibrous material in the circulating water to prevent it from reaching the pumps while permitting entrained particulate matter to pass through the perforations. The controlled-debris elements have a specific gravity substantially the same as the circulating water so they are entrained in the cooling water that is drawn toward the strainers and intimately intermix with the fibrous and particulate matter in the cooling water. The elements are configured to provide open structures in the bed formed on the plate surfaces to distribute fibers in the flow away from the surface and maintain cavities between the elements for the particulates.
