Claims
- 1. A system for the steam reforming of hydrocarbons which comprises:
- (1) in parallel
- (a) a steam reforming furnace having a radiant section, reforming tubes in said radiant section, and means for producing radiant heat, for primary reforming a first mixture of hydrocarbon feed and steam;
- (b) an exchanger-reactor having indirect heat exchange means for primary reforming a second mixture of hydrocarbon feed and steam passing therethrough;
- (2) a secondary reformer;
- (3) means for combining the effluents from said steam reforming furnace and said exchanger-reactor, and introducing said combined effluents to said secondary reformer; and
- (4) means for passing the effluent from said secondary reformer to said exchanger-reactor to supply the heat for the primary reforming of said mixture of hydrocarbon feed and steam passing therethrough.
- 2. A system according to claim 1 wherein said exchanger-reactor is a tube and shell heat exchanger.
- 3. A system according to claim 2 wherein said shell is a high pressure vessel.
- 4. A system according to claim 2 wherein said means for passing the effluent to said exchanger-reactor is from said secondary reformer to the shell of said exchanger-reactor.
