Embodiment Construction

[0027] specific implementation plan

[0028]The subject matter of the invention has been described in detail, however, the description itself is not intended to limit the scope of the invention. The subject matter thus described can also be embodied in other ways, to include different steps or combinations of steps similar to those described herein, along with other present or future technologies. Furthermore, while the term "step" may be used herein to describe various elements of the methods employed, the term should not be construed to imply any particular order among the various steps disclosed herein, unless clearly defined in the description. Although the description below refers to delayed coker drum quench operations, the systems and methods of the present invention are not limited thereto and may be applied to other operations to achieve similar results.

[0029] now refer to figure 2 , a schematic diagram illustrating an improved delayed coking quench overflow sys...

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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Patent Application Serial No. 13 / 803,848, filed March 14, 2013, the specification of which is hereby incorporated by reference. [0003] Statement Regarding Federally Funded Research [0004] not applicable. technical field [0005] The present invention generally relates to delayed coker drum quench overflow systems and methods. More specifically, the present invention relates to the removal of hydrocarbon particulates from overflow streams in delayed coker drum quenching operations before the overflow streams enter a closed discharge system. Background technique [0006] Coking is one of the older refining processes. The purpose of the coking plant is to convert heavy residues (such as tar, bitumen, etc.) into lighter, more valuable motor fuel blends. Refinery coking is controlled, strictly, by thermal cracking. This is the process of cracking, or breaking down, where hi...
