Abstract
An apparatus including a coke drum for coking hydrocarbon substances, a valve disposed near the bottom of the coke drum, and a discharge conduit for removing coke from the coke drum, wherein the discharge conduit is connected to the valve such that when the valve is open, the coke may be removed via the discharge conduit.
Claims22
An apparatus comprising:
- a coke drum for coking hydrocarbon substances, the coke drum having a bottom flange;
- a funnel removably attached to said bottom flange;
- a valve connected to said funnel, said valve being actuatable between an open position and a closed position;
- a steam supply providing a source of steam at a higher pressure than a pressure applied to said valve from contents of said coke drum located upstream of said valve, said steam supply supplying the steam at the higher pressure to said valve such that if said valve leaks, said steam supply causes said valve to fail safe;
- and
- a discharge conduit disposed downstream of said valve for removing coke from said coke drum when said valve is in the open position.
3 more elements
A closed system for discharging coke from a coke drum, said system comprising:
- a coke drum having a bottom flange;
- a funnel removably attached to said bottom flange;
- a ball valve connected to said funnel, said valve being actuatable between an open position and a closed position;
- a discharge conduit disposed beneath the ball valve;
- and
- a steam supply providing a source of steam at a higher pressure than a pressure applied to said ball valve from contents of said coke drum located upstream of said ball valve, said steam supply supplying the steam at the higher pressure to said ball valve such that if said ball valve leaks, said steam supply causes said ball valve to fail safe,
- wherein coke exiting the coke drum is enclosed until exiting said discharge conduit.
4 more elements
A discharge system for a coke drum, said system comprising:
- a coke drum having a bottom flange;
- a funnel removably attached to said bottom flange;
- a side conduit for feeding petroleum to said coke drum;
- guiding means for guiding coke from a bottom of said coke drum;
- sealing means, disposed downstream of said funnel and upstream of said guiding means, for sealing coke in said coke drum;
- and
- steam supplying means providing a source of steam at a higher pressure than a pressure applied to said sealing means from contents of said coke drum located upstream of said sealing means, said steam supplying means supplying the steam at the higher pressure to said sealing means such that if said sealing means leaks, said steam supplying means causes said sealing means to fail safe.
4 more elements
An apparatus comprising:
- a coke drum for coking hydrocarbon substances, the coke drum having a bottom flange;
- a side conduit connected to a lower portion of said coke drum for feeding and draining said coke drum;
- a funnel removably attached to said bottom flange;
- a valve connected to said funnel, said valve being actuatable between an open position and a closed position;
- a steam supply providing a source of steam at a higher pressure than a pressure applied to said valve from contents of said coke drum located upstream of said valve, said steam supply supplying the steam at the higher pressure to said valve such that if said valve leaks, said steam supply causes said valve to fail safe;
- and
- a discharge conduit disposed downstream of said valve for removing coke from said coke drum when said valve is in the open position,
- wherein said coke drum is filled with the hydrocarbon substances via said side conduit before coking.
