Abstract
A reformer for production of synthesis gas may include a reformer firing space having a reformer base, reformer walls, and a reformer roof. The reformer may include a first reformer tube and a second reformer tube, with at least sections of the first reformer tube and the second reformer tube being arranged within the reformer firing space. At least one reformer burner is disposed outside the reformer firing space. A cooling duct on or beneath the reformer base is disposed between the first reformer tube and the second reformer tube. The first reformer tube and the second reformer tube can be connected to a collecting system outside the reformer firing space, with the collecting system being disposed beneath the reformer base.
Claims19
A reformer for at least one of producing synthesis gas or hydrogen or dehydrogenating propane or butane, the reformer comprising:
- a reformer firing space having a reformer base, reformer walls, and a reformer roof,
- a first reformer tube and a second reformer tube, wherein sections of the first reformer tube and the second reformer tube are disposed within the reformer firing space;
- a reformer burner disposed within the reformer firing space;
- and
- a cooling duct configured to cool the reformer base to a range between 80° C. and 50° C. on or beneath the reformer base, with the cooling duct being disposed between the first reformer tube and the second reformer tube, wherein the cooling duct is connected to a combustion air conveying device configured as a fan, wherein the cooling duct is spaced apart from the reformer firing space.
A process for producing synthesis gas, the process comprising:
- introducing a hydrocarbon mixture and steam at a temperature of 400° C. to 700° C. and a pressure of 10 bar to 50 bar into a reformer, wherein the reformer comprises:
- a reformer chamber having a reformer base,
- a first reformer tube and a second reformer tube, wherein sections of the first reformer tube and the second reformer tube are disposed in the reformer chamber,
- a reformer burner disposed within the reformer chamber,
- a flue gas ventilation duct between the first reformer tube and the second reformer tube, and
- a cooling duct configured to cool the reformer base to a range between 80° C. and 50° C. disposed on the reformer base between the first reformer tube and the second reformer tube;
- guiding a cooling medium through the cooling duct, with the cooling medium having an inlet temperature of −20° C. to 100° C.;
- and
- obtaining a mixture comprising hydrogen and carbon monoxide.
