1. A process for producing syngas, the process comprising:
reacting a preheated 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, carbon dioxide, water, and soot;
heating a boiler feed water stream by indirect heat exchange with the first syngas stream to produce a steam stream and a second syngas stream; and
heating one of the steam stream and a mixed feed stream by indirect heat exchange with the second syngas stream to produce a third syngas stream, wherein the mixed feed stream comprises methane and an oxidant selected from the group consisting of water and carbon dioxide;
removing soot from the third syngas stream without contacting the third syngas stream with liquid water to produce a cleaned third syngas stream; and
heating the other of the steam stream and the mixed feed stream by indirect heat exchange with the cleaned third syngas stream or a stream derived from the cleaned third syngas stream;
wherein the preheated feed stream comprises the mixed feed stream.
