Delayed coking drum quench overflow systems and methods
First Claim
Patent Images
1. A method for removing hydrocarbon particulates from an overflow stream in a delayed coking quench overflow system, which comprises:
- pumping an overflow stream comprising a fluid and hydrocarbon particulates from a coke drum through a filter system;
removing a portion of the hydrocarbon particulates from the overflow stream as the overflow stream is pumped though the filter system, wherein the filter system removes hydrocarbon particulates from the overflow stream that are as small as about 10-25 microns in size; and
pumping the overflow stream from the filter system through a closed blowdown system, which comprises at least one of a blowdown condenser and a settling drum.

Abstract
Delayed coking drum quench overflow systems and methods, which relate to removing hydrocarbon particulates from an overflow stream in a delayed coking drum quench operation. In one embodiment, an improved overflow system incorporates one or more filters to remove hydrocarbon particulates from the system before passing through a conventional closed blowdown system.

9. A delayed coking quench overflow system, which comprises:
-
a coke drum; a closed blowdown system, which comprises at least one of a blowdown condenser and a settling drum; and a filter system connected to the coke drum at one end by a fluid passageway and connected to the closed blowdown system at another end by another fluid passageway, wherein the filter system removes hydrocarbon particulates from an overflow stream from the coke drum that are as small as about 10-25 microns in size. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
