Abstract
An improved center feed nozzle with a dual nozzle configuration. A bulge with a curve going downward into the flow pat and then pulling back toward the wall at the first nozzle is formed between the flow source and the first nozzle. An extended partition divides the first nozzle and the second nozzle. The geometry directs flow more evenly between the first nozzle and the second nozzle, thus reducing the plume height as well as the pressure drop without directing the flow into the coke drum walls. The bulge may be hollowed and connected to a steam source to reduce temperature gradients and the fatigue that results therefrom by maintain a more uniform wall thickness heated from both inside and outside.
Claims21
An improved center feed device (CFD) flow control nozzle for directing fluid feedstock into a coke drum, comprising:
- a nozzle body having a sidewall defining an internal chamber and a primary flow axis extending therethrough;
- a first segment of the internal chamber having a substantially symmetrical cross-sectional flow path;
- a second segment downstream of the first segment and including a bulge protruding from the sidewall into the internal chamber so as to reduce a cross-sectional area of the flow path;
- and
- a third segment downstream of the second segment and including a first exit port and a second exit port.
A CFD flow control nozzle for use in delayed coking, comprising:
- a nozzle body defining an internal flow path;
- a bulge protruding into the internal flow path upstream of a first exit port;
- a second exit port positioned adjacent the first exit port;
- and
- a partition separating the first exit port from the second exit port,
- wherein the bulge is positioned and configured such that, during operation, a greater proportion of total fluid discharge exits through the first exit port than would occur in an otherwise identical CFD nozzle lacking the bulge.
