Abstract
An improved delayed coking unit with at least one coke drum wherein said coke drum comprises a substantially closed interior, a top portion having an aperture, an overhead vapor outlet nozzle removably connected to the aperture, and a deflector for deflecting solids and heavy hydrocarbon liquids from exiting said interior of said coke drum through said aperture.
Claims15
A coke drum for a delayed coking unit, wherein said coke drum comprises:
- a substantially closed interior;
- a top portion of said drum having an aperture therethrough;
- an overhead vapor outlet nozzle connected to said aperture;
- and
- a deflector for deflecting solids and heavy hydrocarbon liquid from exiting said interior of said coke drum through said aperture.
A method of reducing escape of solids and heavy hydrocarbon liquids from a coke drum having a top portion with an aperture, an overhead vapor outlet nozzle connected to said aperture, and means for deflecting solids and heavy hydrocarbon liquids from exiting said interior of said coke drum through said aperture, said method comprising the steps of:
- introducing hydrocarbon feed into said coke drum;
- venting said coke drum through said aperture;
- and
- reducing said amounts of solids and heavy hydrocarbon liquids from exiting said coke drum by deflecting said solids and heavy hydrocarbon liquids from said aperture.
A method of reducing escape of solids and heavy hydrocarbon liquids from a coke drum having a top portion with an aperture, and an overhead vapor outlet nozzle connected to said aperture, which method comprises:
- introducing hydrocarbon feed into said coke drum;
- venting said coke drum through said aperture;
- impinging said solids and liquid hydrocarbons on a deflector plate in said drum to discourage escape of said solids and hydrocarbon liquids from said coke drum.
