Abstract
A process for producing syngas that uses the syngas product from an oxygen-fired reformer to provide all necessary heating duties, which eliminates the need for a fired heater. Without the flue gas stream leaving a fired heater, all of the carbon dioxide produced by the reforming process is concentrated in the high-pressure syngas stream, allowing essentially complete carbon dioxide capture.
Claims18
A process for producing syngas, the process comprising:
- reacting a reformer feed stream comprising methane and an oxidant selected from the group consisting of water and carbon dioxide with an oxygen-enriched stream to produce a first syngas stream comprising hydrogen, carbon monoxide, and carbon dioxide;
- heating a preheated mixed feed stream by indirect heat exchange with the first syngas stream to produce the reformer feed stream and a second syngas stream;
- heating a boiler feed water stream by indirect heat exchange with the second syngas stream to produce a saturated steam and a third syngas stream;
- and
- heating the saturated steam by indirect heat exchange with the third syngas stream to produce a superheated steam and a fourth syngas stream.
