Steam methane reformer system and method of performing a steam methane reforming process
An apparatus includes a furnace having at least one bayonet reforming tube. The furnace is adapted to receive a gas including a hydrocarbon and at least one of steam and carbon dioxide via the bayonet reforming tube, heat and catalytically react the gas to form syngas at a first temperature, cool the syngas to a second temperature lower than the first temperature, and eject the syngas from the tube. The furnace has a first effluent stream including flue gas and a second effluent stream including syngas. The apparatus also includes a first heat recovery section adapted to transfer heat from the first effluent stream to a first heat load including one of air, water, and steam, and a second heat recovery section adapted to transfer heat from the second effluent stream to a second heat load.
1. An apparatus comprising:
at least two furnaces, each comprising at least one bayonet reforming tube, each furnace being adapted to:
receive a process gas comprising a hydrocarbon and at least one of steam and carbon dioxide via the bayonet reforming tube;
heat and catalytically react the process gas to form syngas at a first temperature;
cool the syngas to a second temperature lower than the first temperature; and
eject the syngas from the tube;
wherein each of the at least two furnaces has a flue gas effluent stream and a syngas effluent stream;
a single common heat recovery section operably connected to each of the at least two furnaces, wherein the flue gas effluent streams of each of the at least two furnaces are in thermal communication with a heat load within the common heat recovery section,
wherein the process gas of each of the at least two furnaces bypasses the single common heat recovery section before being received by a respective bayonet reforming tube of each of the at least two furnaces.
2. The apparatus of claim 1 further comprising:
a heat recovery section comprising one or more burners adapted to perform further heating of a load.
3. The apparatus of claim 1 , further comprising at least three furnaces and a single common first heat recovery section.
4. The apparatus of claim 1 , wherein the heat load comprises:
a first heat exchanger in which heat is exchanged between the common flue gas effluent stream and steam;
a second heat exchanger in which heat is exchanged between the common flue gas effluent stream and boiler feed water; and
a third heat exchanger in which heat is exchanged between the common flue gas effluent stream and air.
