Abstract

The present invention features a tangential injection system for use within a delayed coking system, or any other similar system. The tangential injection system comprises a spool, a tangential dispenser, and a hydro blasting system, wherein the tangential dispenser comprises a delivery main surrounding the perimeter of the spool and that functions to deliver a residual byproduct or other material to a plurality of feed lines positioned at a position or at distances around the delivery main for the purpose of providing tangential dispensing of the residual byproduct into the vessel, thus effectuating or inducing even thermal distribution throughout the vessel.

Claims

1. A tangential dispenser comprising:

a delivery main in fluid connection with a reservoir vessel, said delivery main comprising;

an inlet capable of receiving byproduct from a feed source;

a curved pipe segment extending from and in fluid connection with said inlet to further receive and deliver said byproduct; and

a plurality of feed lines in fluid connection with said curved pipe segment and said reservoir vessel, said feed lines positioned substantially tangential with said reservoir vessel and comprise a piped section in fluid connection with a port in said reservoir vessel, said feed lines tangentially dispensing said residual byproduct into said reservoir vessel to provide even thermal distribution throughout said reservoir vessel during a process.

2. The tangential dispenser of claim 1, wherein said feed lines are spaced an equidistance from one another around said delivery main.

3. The tangential dispenser of claim 1, wherein said feed lines are offset from one another and spaced at varying intervals around said delivery main.

4. The tangential dispenser of claim 1, wherein said feed lines comprise a cumulative cross-sectional area less than or substantially equal to a cross-sectional area of said delivery main to proportionately reduce the volume of said residual byproduct remaining in said delivery main after each feed line.

5. The tangential dispenser of claim 1, wherein said feed lines comprise varying cross-sectional areas.

6. The tangential dispenser of claim 1, wherein said feed lines comprise identical cross-sectional areas.

7. The tangential dispenser of claim 1, wherein said feed lines comprises vector positioning, such that they may be positioned at any desired angle along the x-y-z coordinate with respect to either one or both of said delivery main and said reservoir vessel to obtain tangential dispensing of said byproduct.

8. The tangential dispenser of claim 1, wherein said feed lines comprise an orientation selected from inclined and declined, said inclined orientation existing as said feed line originates from said delivery main and extends upward to said port in said reservoir vessel, and said declined orientation existing as said feed line originates from said delivery main and extends downward to said port in said reservoir vessel.

9. The tangential dispenser of claim 1, further comprising a hydro blasting system to purge material from said delivery main and said feed lines, said hydro blasting system comprising:

an access line in fluid connection with said delivery main;

a delivery port providing access to said access line from without said system by one or more cleaning and purging devices; and

sealing means for sealing said access line during a manufacturing process.

10. The tangential dispenser of claim 1, wherein said reservoir vessel is a coke drum as contained within a delayed coking system.

11. The tangential dispenser of claim 1, wherein said reservoir vessel is a spool attaching two flanged components together.

12. The tangential dispenser of claim 1, wherein said delivery main annularly surrounds said reservoir vessel.

13. The tangential dispenser of claim 1, wherein said delivery main comprises varying cross-sectional areas along its span around said reservoir vessel to provide for and accommodate varying volumes of said residual byproduct.

14. The tangential dispenser of claim 1, wherein said residual byproduct is tangentially dispensed within said reservoir vessel at an angle between 0 and 90 degrees.

15. The tangential dispenser of claim 1, wherein a majority of said residual byproduct is dispensed within said reservoir vessel at an angle between about 20 and 30 degrees.

16. The tangential dispenser of claim 1, wherein said feed lines comprise an oblique end.

17. The tangential dispenser of claim 1, wherein said port on said reservoir vessel comprises an oblique shaped segment leading into said reservoir vessel.

18. The tangential dispenser of claim 1, wherein said residual byproduct sprays across a sidewall interior in a lateral, tangential manner.

19. The tangential dispenser of claim 1, wherein said port comprises an oblique configuration larger in size than an adjacent opening in said feed line to provide a low-barrier entry of said residual byproduct into said reservoir vessel.

20. The tangential dispenser of claim 1, wherein said delivery main extends around at least a portion reservoir vessel.

21. The tangential dispenser of claim 1, wherein said delivery main surrounds said reservoir vessel.

22. A tangential injection system for use within a delayed coking system, said tangential injection system comprising:

a spool fittable to a coke drum and a de-header valve;

a tangential dispenser coupled to said spool, said tangential dispenser comprising;

a delivery main in fluid connection with a reservoir vessel, said delivery main comprising;

an inlet capable of receiving byproduct from a feed source;

a curved pipe segment extending from and in fluid connection with said inlet to further receive and deliver said byproduct;

a plurality of feed lines in fluid connection with said delivery main and said spool, said feed lines are tangential to said spool and comprise a piped section in fluid connection with a port in said spool, said feed lines dispensing said residual byproduct into said spool in a tangential manner to provide even thermal distribution throughout said spool during a manufacturing process; and

a hydro blasting system operable with said tangential dispenser, said hydro blasting system providing access to said delivery main by a cleaning device to purge said tangential dispenser of residual byproduct upon completion of a manufacturing cycle.

23. A delayed coking system comprising:

a feed source capable of delivering a petroleum byproduct to said delayed coking system;

a reservoir vessel;

a de-header valve;

a tangential injection system in operation with said reservoir vessel, said tangential injection system comprising;

a tangential dispenser coupled to said spool, said tangential dispenser comprising;

a delivery main in fluid connection with a reservoir vessel, wherein said delivery main comprises an inlet capable of receiving said byproduct from said feed source and a curved pipe segment extending from said inlet to further receive and deliver said byproduct;

a plurality of feed lines in fluid connection with said delivery main and said reservoir vessel, said feed lines oriented substantially tangential with said reservoir vessel and comprising a piped section in fluid connection with a port in said reservoir vessel, said feed lines dispensing said residual byproduct into said reservoir vessel in a tangential manner to provide even thermal distribution throughout said reservoir vessel during a manufacturing process; and
