Abstract

A system for analyzing a coking system comprises a coking system comprising a first coke drum and a second coke drum, and a user device communicatively coupled to a hardware implemented analysis engine. The coking system configured to collect and transmit coke drum data to the hardware implemented analysis engine. The hardware implemented analysis engine is configured to: receive an estimation of an altered life span of the first coke drum relative to a design life span of the first coke drum, analyze an effect of adding an additional coke drum to the coking system based on the altered life span, and provide a result item related to the analysis to the user device. The estimation of the altered life span is based on the coke drum data.

Claims

1. A system for analyzing a coking system, comprising:

an existing coking system comprising;

a first coke drum coupled with a first sensor, wherein the first coke drum comprises a residual feed, and

a second coke drum coupled with a second sensor, wherein the second coke drum is fluidly coupled to the first coke drum, and wherein the first sensor and the second sensor are each configured to collect and transmit coke drum data to a hardware implemented analysis engine; and

a user device communicatively coupled to the hardware implemented analysis engine,

wherein the hardware implemented analysis engine is configured to;

receive the coke drum data from the first sensor and the second sensor;

estimate a change in a design life span of the first coke drum using the coke drum data;

estimate an altered life span of the first coke drum using the estimated change in the design life span of the first coke drum;

analyze an effect of modifying an operating parameter of the first coke drum;

determining that a modification of an operating parameter increases the life span of the first coke drum;

provide a result item related to the modification of the operating parameter to the user device; and

modify the operating parameter of the first coke drum based at least in part on the determination that the modification of the operating parameter increases the life span of the first coke drum.

2. The system of claim 1, wherein the user device comprises a user interface.

3. The system of claim 2, wherein the hardware implemented analysis engine is configured to receive the design life span from the user device.

4. The system of claim 1, wherein the altered life span is a shortened life span, projected to result from operating the first coke drum with a shortened cycle time.

5. The system of claim 4, wherein the coke drum data comprises an identification of a damage in at least one of the first coke drum or the second coke drum, wherein the damage is associated with the shortened cycle time.

6. The system of claim 5, wherein the damage comprises bulging.

7. The system of claim 5, wherein the damage comprises a crack.

8. The system of claim 5, wherein the damage comprises thinning in a wall.

9. The system of claim 4, wherein the coke drum data comprises an identification of a problematic temperature gradient (PTG) of a portion of a wall in at least one of the first coke drum or the second coke drum, wherein the temperature gradient is associated with the shortened cycle time.

10. The system of claim 4, wherein the hardware implemented analysis engine is configured to:

modify the operating parameter by modifying a processing parameter to reduce a problematic temperature gradient (PTG) in at least one of a skirt attachment, a pressure boundary, or a supporting element during a heating step.

11. The system of claim 1, wherein the altered life span is an increased life span, projected to result from operating the first coke drum with a lengthened cycle time.

12. The system of claim 11, wherein the increased life span is estimated to be at least twice the design life span.

13. The system of claim 11, wherein the increased life span is estimated to be at least three times the design life span.

14. The system of claim 1, wherein at least one of the first coke drum or the second coke drum has been in operation.

15. The system of claim 1, wherein the hardware implemented analysis engine is further configured to:

receive an estimation of a time to failure of the first coke drum based at least in part on a bulge in at least one of the first coke drum or the second coke drum.

16. The system of claim 1, wherein the analysis engine is further configured to receive an estimation of a time to failure of the first coke drum based at least in part on a crack in at least one of the first coke drum or the second coke drum.

17. The system of claim 1, wherein the hardware implemented analysis engine is further configured to:

receive an estimation of a time to failure of the first coke drum based at least in part on a thinning in at least one of the first coke drum or the second coke drum.

18. The system of claim 1, wherein the hardware implemented analysis engine is further configured to:

receive an estimation of a time to failure of the first coke drum based at least in part on a problematic temperature gradient in at least one of the first coke drum or the second coke drum.

19. The system of claim 1, wherein the hardware implemented analysis engine is configured to:

analyze an effect of adding an additional coke drum to the coking system based on the altered life span; and

wherein the system further comprises;

a computer configured to produce a physically perceivable rendering of the additional coke drum.

20. The system of claim 1, wherein the hardware implemented analysis engine is configured to analyze the effect of modifying the operating parameter by using a database storing:

drum data, design life span data, operating parameter data, and life span data corresponding to a change in the operating parameter.

21. The system of claim 1, wherein the hardware implemented analysis engine is configured to:

receive the coke drum data from the first sensor and the second sensor on a periodic basis.
