Abstract
Description
- This invention relates to a bottom unheading device for vertical vessels, such as coking drums which are adapted for remote operation. It particularly relates to such a bottom unheading device for removing and replacing a lower cover unit for coking drums and to a method for remote operation of the unheading device.
- During the operation of delayed coking drums or units for coking various heavy hydrocarbon materials in petroleum refinery operations, the resulting coke is deposited progressively on the inner walls of the drum and when full must be removed, usually at 36-48 hour intervals. A typical decoking apparatus for such coking drums is disclosed by U.S. Patent No. 4,611,613 to Kaplan. Such coke removal from coking drums is accomplished through an opening in the lower end of the vertically-oriented drum, and is usually accomplished by manually removing a lower flange cover and installing a chute to direct the coke removed to a desired location, such as to a happer or rail car. Because the coking drum operates at relatively high temperatures of 800-900°F, such removal of the hot coking drum lower cover by manual means is slow and hazardous and is therefore undesirable.
- A useful remotely operated unheading device for coking drums is disclosed by co-pending patent application Serial No. 917,443 to Malsbury et al. However, this device has been found to have some deficiencies, which have been overcome by this invention. Accordingly, the invention advantageously provides an improved bottom unheading device for coking drums for remote safe and reliable removal and replacement of coking drum lower cover unit, and enables more convenient and rapid removal of coke from the drum during decoking operations.
- The present invention provides an improved unheading device for the bottom flange of vertically oriented vessels such as coking drums. This device is adapted for remote unfastening and removal of a lower cover unit, moving it transversely to one side to permit coke removal from the drum, and subsequent replacement of the cover unit onto the coking drum. The unheading device according to the invention includes a cover unit adapted for being fastened pressure-tightly to a lower flange of a coking drum bolt detensioning and pivotable clamping means adapted for unfastening a plurality of bolts in the cover unit and swinging the bolts radially outward and upward so as to permit downward removal of the cover unit, a vertically movable lifting frame means adapted for supporting and lowering the cover unit from the drum lower flange, and a carriage unit supported by said lifting frame and adapted for lateral movement of the cover unit relative to the lifting frame and coking drum by dual horizontal piston actuator means for moving the cover unit laterally to a side position. The unheading device also includes a chute attached to the lifting frame, so that the chute can be raised to contact the coking drum lower flange for conveying the coke removed from the drum. The unheading device also provides for the cover unit to be returned laterally so as to be in vertical alignment with the coking vessel lower flange, lifted up into engagement with the lower flange, after which the cover unit fasteners can be rotated downwardly and refastened to reclamp the cover unit into place on the coking drum lower flange.
- The multiple bolt fasteners of the unheading device are pivotally attached to the coking vessel lower flange, so they can be swung radially outward and upward by vertically-oriented piston actuators attached to the vessel, thus permitting lowering of the cover unit. Preferably, two adjacent pivotable bolts are attached to a single piston actuator. The lifting frame means is rectangular-shaped and is supported and moved vertically by four equally-spaced hydraulic piston actuators, which are attached at their lower ends to the frame outer corners and attached at their upper ends to the coking vessel.
- A chute is attached to the frame for use in removing the deposited coke from the vessel. After the cover unit mating flanges are unfastened, the frame means can lower the cover unit by operation of the four vertically-oriented piston actuators, after which the cover unit can be moved laterally from beneath the coker drum by dual horizontal piston actuators located along opposite sides of the cover unit. The frame means four piston actuators then raise the coke chute into contact with the coking drum lower flange into the decoking position, so that the accumulated coke can be removed from the vessel through the chute..
- After decoking of the vessel is completed, the four piston actuators then lower the frame means and the attached coke chute, after which the cover unit is then moved laterally back to a position below the drum lower flange by action of the dual horizontal piston actuators. The frame member then raises the cover unit into mating position for rebolting it to the coking drum lower flange. The bolt detensioning and lift mechanisms for the cover unit and coke chute are advantageously operated by hydraulic pistons operated by remote control. This unheading device and chute arrangement can be advantageously applied to either new or existing delayed coking drums, for decoking the drums much more rapidly and with increased reliability and safety at intervals of 36-48 hours operation.
- The present invention also provides a method for removing a lower cover unit from vertically oriented vessels such as coking drums for coke removal, and replacing the cover unit on the vessel or coking drum. The method includes the steps of unfastening a flanged joint provided between a lower flange of the delayed coking vessel and a removable cover unit by detensioning a plurality of bolt fasteners using remotely operated hydraulic devices for detensioning the fastener bolts, and swinging the bolts radially outwardly and upwardly, then lowering the cover unit and moving it laterally to a side position. Next, a coke chute is raised and connected to the coking vessel lower flange for removing the coke contents from the vessel. Following such coke removal, the chute is lowered and the cover unit is moved laterally so as to be in vertical alignment with the coking vessel lower flange, and then raised back into its original position against the coking vessel flange. The fastener bolts are then swung downwardly into position and retensioned to reconnect the cover unit onto the coking vessel lower flange.
- It is an advantage to have a vessel or coking drum lower cover unit that can be conveniently and safely removed from the coking drum, using a remotely-operated unheading device, which loosens the plurality of bolt fasteners and pivots the fasteners outwardly, then lowers the cover unit and moves it laterally aside. Such unheading device and method permits more rapid and reliable removal of coke deposited in a coking drum, so as to increase the available operating time for the drum, and also improves personal safety by avoiding undesirably exposure of personnel to hot hydrocarbons, steam and water during such unheading operations. Vertically oriented vessels on which this unheading device and method can be advantageously used include coking drums, reactors, or any vessel of a similar configuration, where danger to personnel exits during an unheading operation.

- As generally shown by the Fig. 1 drawing, a delayed coking drum or
vessel 10 is vertically-oriented and supported by anadjacent support structure 11 and also by alower platform stucture 12 provided below thedrum 10. Such a delayed cokingdrum 10 for use in petroleum refineries are usually 20-25 ft. diameter and 75-100 ft. tall, and have a conicallower portion 10a attached to alower flange 13 which is usually 5-7 ft. diameter. A removablelower cover unit 14 is pressure-tightly attached to thelower flange 13 by a plurality of clamp fastener means 20. The coke deposited progressively in cokingdrum vessel 10 is removed from the drum periodically as needed by removing thelower cover unit 14 and hydraulically cutting the coke from within the vessel, so that the coke falls through achute 15 into a storage pit or a rail car (not shown) for further use. - The
cover unit 14 is fastened onto thelower flange 13 ofvessel 10 by multiple pivotable clamp fastener means 20, as shown in greater detail by Figs. 2 and 3.Cover unit 14 includes acradle support structure 16 having dualhorizontal skid members 18 extending along opposite sides of the cradle, and which are supported by a rectangular-shaped frame member 30. It will be noted thatcover unit 14 also includes alateral conduit 19 used for feeding hydrocarbon, steam and water materials into thecoke drum 10 and to drain water from the drum. As is shown in Figs. 2 and 3 and further shown in Fig. 4, 16-48 swing type fasteners 20 (depending on the flange diameter and pressure rating) are provided evenly spaced around the periphery offlange 13 for pressure-tightly clamping thecover unit 14 onto thelower flange 13 ofvessel 10. - As shown in greater detail by Figs. 5-7, each
clamp fastener device 20 is constructed and operated similarly, and includes aclamp arm 21 which is pivotably attached at itsupper end 21a to flange 13 by apivot pin 22 pivotably secured to the upper surface offlange 13 at near the outer perimeter of the flange. The other orlower end 21b ofclamp arm 21 is pivotally attached to a lower end of apiston actuator 24, and the upper end ofactuator 24 is pivotably attached at 25 to theouter wall portion 10a ofcoker drum 10. Thelower end 21b of eachclamp 21 is also rigidly connected viapivot pin 22 to the upper end of afastener bolt 26, which is provided in avertical slot 27 provided in both thelower flange 13 ofvessel 10 and in themating cover unit 14. Also, a remotely operatedtensioning unit 28 is provided attached to eachbolt 26 below thecover unit 14. Thebolt tensioning device 28 may be similar to that described in U.S. Patent 3,015,975 to Biach, which is incorporated herein by reference to the extent necessary to adequately disclose the present invention. Thetensioning units 28 are usually operated by a suitable hydraulic pressure source connected to each tensioning unit. Preferably, each two adjacentpivotable bolts 26 are attached to asingle piston actuator 24 attached to anelongated pivot pin 23. - When it is desired to open the flanged joint between the drum
lower flange 13 andcover unit 14, thebolt tensioning unit 28 are first remotely actuated to detension thebolts 26 thereby lowering thecover unit 14 andcradle 16 by a distance of 0.25-1 inch by the liftframe support device 30. Then, theswing actuator pistons 24 are actuated, so as to swing thebolts 26 radially outwardly and upwardly to a disconnected or unfastened position as shown in Fig. 8. - For supporting and lowering the
cover unit 14 from the coker vessellower flange 13, the liftframe support device 30 is provided below and in supporting engagement with skidmember 18, as is shown by Figs. 2, 3 and 8. Theframe device 30 is adapted for contacting the lower surface ofcradle support carriage 16 and skidmember 18 of thecover unit 14. Theframe device 30 includes four vertically-extendingbrackets 32 located at its four corners, and each pivotally attached to a vertically-oriented piston actuator 34 adapted for controllably lifting and lowering theframe unit 30. The upper end of eachpiston actuator 34 is pivotably attached to theconical portion 10a of cokingdrum 10. After thefastener bolts 26 have been detensioned and thecover unit 14 initially lowered by 0.25-1 inch and is being supported byframe device 30, thebolts 26 are then swung radially outwardly and upwardly fromflange 13. Then thecover unit 14 is further lowered byframe unit 30 as shown by Fig. 8, and is then moved laterally aside as shown by Figs. 9 and 10. The vertical movements forcover unit 14 are accomplished by it being vertically movable by the four vertically-orientedpiston actuators 34. Theframe device 30 is lowered onto at least two and usually fouralignment pins 31, as shown in Fig 3, so that theframe 30 remains in a fixed horizontal position relative to theflange 13 ofcoking drum 10. - After the
cover unit 14 has been lowered by action offrame 30vertical piston actuators 34 as shown by Fig. 8, thecover unit 14 is then moved side laterally by dualhorizontal piston actuators 36, which extend substantially horizontally along each side ofcover unit 14. Theactuators 36 are each connected at theirforward end 36a to coverunit 14 bylug 35, and are each connected at their rearward end to anchor means 37. The orientation and relative position of the parts of liftingframe device 30 is additionally shown in plane view of platform support device by Fig. 11. - While the
cover unit 14 is moved aside laterally to an offset position as shown by Figs. 9 and 10, by extension action of thepiston actuators 36, thelower skid member 18 is retained by dual guide surfaces 33a and 33b which are provided extending along opposite sides of theframe unit 30. The forward end portion ofcradle support 16 is preferably partially supported bydual rollers 38 running alongparallel tracks 39 provided indeck 40. The rear end ofcradle support 16 rests on achair member 41 attached todeck 40. Then, after the cover unit has been moved laterally to one side,collapsible chute 15 which is attached to lower portion 30a of theframe device 30, is simultaneously raised by action of the fourpiston actuators 34 so thatchute 15 contacts thelower flange 13 of thecoker vessel 10. An enlarged partial view of thechute 15 being in contact with thelower flange 13 of thecoker vessel 10 is shown by Fig. 12. The coke is removed from within thecoking drum 10 and falls through thechute 15 to a storage pit or rail car (not shown) for further processing or use. - After the decoking operation for the
coker drum 10 is completed, theframe unit 30 and attachedchute 15 are lowered, and then coverunit 14 is returned to its original position and reconnected onto thedrum flange 13, as was shown by Figs. 2 and 3. This return movement forcover unit 14 is accomplished by first loweringframe 30 andcoke chute 15 by the fouractuator pistons 34, then retractingdual piston actuators 36 to move thecover unit 14 laterally to a position in vertical alignment belowflange 13, then raisingframe 30 so thatcover unit 14 is again placed against and in alignment withlower flange 13. Next, theswing actuators 24 are extended so as to pivot thebolts 26 downwardly into theslots 27, as shown by Figs. 3 and 4. Then themultiple tensioning units 28 are actuated so as to clamp themating flange 13 andcover unit 14 tightly together again. - This invention will be further described by the following example of operations, which should not be construed as limiting the scope of the invention.
- In a coking drum used for delayed coking of petroleum feedstocks, after 36-48 hours of operation sufficient coke is deposited progressively on the inner wall of the drum that removal of the coke is required before continued operation. The coking drum, which is equipped with a lower flange cover unit constructed and operated in accordance with this invention, is shut down, depressurized and the lower head cover unit is removed. Important characteristics of the coker drum lower cover unit and unheading device are as follows: Coker lower flange diameter, inc. 72
Cover unit flange diameter, in. 72
Cover unit length, in. 18
Number offastener swing bolts 36
Swing bolt diameter, in. 1.25
Bolt slot width in flange, in. 1.5
Vertical movement of lift frame, in. 12
Lateral movement of cover unit, in. 105
Lift actuator hydraulic pressure, psig 1500
- Following switch out of the heavy hydrocarbon feed, steam, water quench and draining of the coking drum, the lower cover unit is removed and replaced using the following procedure:
- a) Detension the fastener swing bolts clamping the cover unit to the coking drum lower flange by pressurizing the hydraulically-operated bolt tension units to sufficiently loosen the bolts to lower the cover unit 0.25 - 1 inch onto a lifting frame and to permit the bolts to swing outwardly from the flange periphery.
- b) Pressurize the swing piston actuators to retract and swing fastener bolts outwardly and upwardly, thus freeing the cover unit flange from the coking drum flange.
- c) Pressurize the lift frame actuators and lower the cover unit, then move it aside by pressurizing and extending the dual lateral piston actuators.
- d) Reverse pressurize four lift actuators to move coke chute upwardly to mate with the coking drum lower flange to permit removal of the coke.
- e) Following removal of accumulated coke from the coking drum, lower the coke chute, move the cover unit laterally to be back in vertical alignment with the coking drum flange, and then lift the cover unit to mate with the coking drum flange.
- f) Reverse pressurize swing piston actuator to extend swing a bolts downward into the bolt slots of the cover flange, then actuate the tensioning units to retension the flange bolts to securely reclamp the cover unit onto the lower flange of the coking drum.
- Although this invention has been disclosed broadly and in terms of a preferred embodiment, it will be understood that modifications and variations can be made within the scope of the invention, which is defined by the following claims.
