Abstract

In one aspect, the present invention relates to a coke drum module, the coke drum module includes a support frame. A coke drum is disposed within the support frame. A strut is removably connected to the support frame and the coke drum. The strut becomes unloaded responsive to the coke drum contacting a support pad. The coke drum module further includes a compression member removably connected to the support frame and the coke drum. The compression member is oriented generally perpendicularly to the strut. A rigid connection is present between the coke drum and the support frame during transportation of the coke drum module. Upon removal of the strut and the compression member, the rigid connection is not present.

Claims

1. A coke drum module comprising:

a support frame;

a coke drum disposed within the support frame;

a removable tension strut disposed in the support frame for supporting a weight of the coke drum in a vertical direction;

a removable compression strut disposed in the support frame of the coke drum for supporting the weight of the coke drum in a horizontal direction;

wherein tension is at least partially relieved from the removable tension strut responsive to the coke drum contacting a support pad; and

wherein, upon removal of the removable tension strut and the removable compression strut, the coke drum is not rigidly connected to the support frame thereby facilitating thermal expansion of the coke drum within the support frame.

2. The coke drum module of claim 1, wherein the removable tension strut is oriented generally parallel to a length of the coke drum.

3. The coke drum module of claim 1, wherein the removable tension strut is subjected to tension stress when the coke drum is oriented in a vertical direction.

4. The coke drum module of claim 1, wherein the removable compression strut facilitates transport of the coke drum module.

5. The coke drum module of claim 1, wherein the removable tension strut comprises a slotted hole formed therein, which slotted hole engages a pin disposed on the coke drum.

6. The coke drum module of claim 5, comprising a keeper plate disposed over the slotted hole, which keeper plate prevents movement of the pin within the slotted hole.

7. The coke drum module of claim 5, wherein movement of the pin within the slotted hole relieves the tension stress from the coke drum.

8. The coke drum module of claim 5, wherein contact of the coke drum with the support pad moves the pin within the slotted hole.

9. The coke drum module of claim 8, wherein the removable tension strut is removed after the coke drum contacts the support pad.

10. A coke drum module comprising:

a support frame;

a coke drum disposed within the support frame and connected to the support frame via a selectively de-coupleable connection, the selectively de-coupleable connection supporting a weight of the coke drum in a horizontal orientation and in a vertical orientation;

wherein, when coupled, the selectively de-coupleable connection facilitates transport of the coke drum module; and

wherein, when the selectively de-coupleable connection is decoupled, thermal expansion of the coke drum is facilitated.

11. The coke drum module of claim 10, wherein the selectively de-coupleable connection comprises a removable strut coupled to the coke drum and the support frame.

12. A method of installing a coke drum module, the method comprising:

receiving the coke drum module comprising a coke drum and a support frame, a rigid connection being present between the coke drum and the support frame during transportation of the coke drum module, the coke drum module being in a horizontal orientation during transportation with a weight of the coke drum being supported by a compression strut;

lifting the coke drum module;

turning the coke drum module such that the coke drum is vertically oriented;

responsive to the coke drum contacting a support pad, at least partially unloading a tension strut coupled to the coke drum and the support frame;

positioning the support frame on the support pad; and

removing the tension strut and the compression strut such that the rigid connection is not present after installation of the coke drum module.

13. The method of claim 12, wherein:

The tension strut supports a weight of the coke drum when the coke drum is oriented in a vertical direction; and

the compression strut supports a weight of the coke drum when the coke drum is oriented in a horizontal direction.

14. The method of claim 12, wherein the coke drum comprises a pin that engages a slotted hole formed on the tension strut.

15. The method of claim 14, comprising restraining the pin within the slotted hole via a keeper plate.

16. The method of claim 15, comprising removing the keeper plate prior to coke drum contacting the support pad.
