Systems and methods for improving quenched coke recovery
View Patent ↗The present technology is generally directed to systems and methods for improving quenched coke recovery. More specifically, some embodiments are directed to systems and methods utilizing one or more of a screen, barrier, or reflector panel to contain or redirect coke during or after quenching. In a particular embodiment, a quench car system for containing coke includes a quench car having a base, a plurality of sidewalls, and a top portion. The system can further include a permeable barrier covering at least a portion of the top of the quench car, wherein the permeable barrier has a plurality of apertures therethrough.
1. A quench car system for containing coke prepared for quenching at a quenching site, the quench car system comprising:
a quench car having a base and a plurality of sidewalls defining an interior, designed to carry a volume of coke, and an open upper end portion; and
a permeable barrier substantially covering and operatively coupled with the open upper end portion of the quench car, and positioned to be in a vertically spaced-apart relationship from the volume of coke; the permeable barrier having a plurality of unobstructed apertures therethrough that allow quench fluid to enter the quench car and quench steam to escape the quench car to an environment surrounding the quench car.
2. The quench car system of claim 1 wherein the permeable barrier is removably coupled to the quench car.
3. The quench car system of claim 1 wherein the permeable barrier extends across the open upper end portion of the quench car and at least one sidewall.
4. The quench car system of claim 1 wherein the individual apertures have a diameter from about ¼ inch to about ¾ inch.
5. The quench car system of claim 1 wherein the quench car further comprises a containment plate coupled to one or more sidewalls and positioned with respect to the one or more sidewalls to contain or funnel coke or quench water.
6. The quench car system of claim 5 wherein an individual sidewall comprises a movable gate, and wherein the containment plate is operatively coupled to and extends along the gate, such that the containment plate is movable between a first position when the gate is open and a second position when the gate is closed.
7. The quench car system of claim 5 wherein two sidewalls meet at a corner, and wherein the containment plate is positioned adjacent to the corner and overlaps at least one of the sidewalls.
8. A quench car system for containing coke prepared for quenching at a quenching site, the quench car system comprising:
a quench car having a base and a plurality of sidewalls defining an interior, designed to carry a volume of coke, and an open upper end portion; and
a permeable barrier permanently coupled to and substantially covering, the open upper end portion of the quench car, and positioned to be in a vertically spaced-apart relationship from the volume of coke; the permeable barrier having a plurality of apertures therethrough.
9. The quench car system of claim 1 wherein the permeable barrier comprises stainless steel.
10. The quench car system of claim 1 wherein the permeable barrier is spaced apart from the open upper end portion of the quench car.
11. The quench car system of claim 1 , further comprising a quench tower having a nozzle positioned above the quench car, wherein an individual aperture of the permeable barrier is generally vertically aligned with the nozzle and has a diameter larger than a diameter of another individual aperture of the permeable barrier.
