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 lowing 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.
Claims7
An apparatus for use assisting in the removal of coke and prevention of coke build up in hydrocracking units having tubular furnace reactors, used in the refining of petroleum products, comprising in combination:
- a grid device in the shape of an upside-down basket wherein the grid is defined by bars interconnected to create openings therebetween;
- the grid device being positioned within the tubular furnace reactor of the hydrocracking tower;
- the grid device positioned to fit over the outlet of the reactor;
- and
- the grid device allowing small pieces of coke to pass through to the outlet of the reactor while preventing large pieces of coke from reaching the outlet of the reactor and restricting the flow of process d material through the outlet of the reactor.
