  • Tower bottoms coke catching device
    Patent number: 11891581
    Abstract: A coke catching apparatus for use in hydrocarbon cracking to assist in the removal of coke and the prevention of coke build up in high coking hydrocarbon processing units. The apparatus includes a grid device for preventing large pieces of coke from entering the outlet of the process refining equipment while allowing small pieces of coke to pass through and be disposed of. The coke catching apparatus can be easily disassembled to be removed from the refining process equipment and cleaned.

  • Apparatus and method for reducing fouling in crude refining by reduction of phosphorus
    Patent number: 10435636
    Abstract: A method and apparatus for the reduction of fouling in a crude unit. Chemicals containing Phosphorous are understood to be utilized in the production or transportation of certain types of crude oils. It is believed that the elevated levels of phosphorus are contributing to the excessive fouling observed in the preheat exchanger circuits and crude heaters.

  • Integrating An Atmospheric Fractionator With A Diluent Recovery Unit And A Resid Hydrocracker
    Publication number: 20140008268
    Abstract: This is a unique way to optimize an existing refinery to process heavy bitumen. The upgrade utilizes a diluent recovery unit (DRU) in front of a Resid Hydrocracker.
