Disclosed is a process for humidifying syngas to achieve a water to carbon monoxide molar ratio in the product syngas within a desired range and in which the molar ratio which can be varied over time in response to changes in downstream syngas requirements. The raw syngas is produced by reacting a carbonaceous material with oxygen, water, or carbon dioxide and can be combined with a diluent to produce a diluted syngas stream which can be cooled and contacted with liquid water to give a humidified syngas. The H2O:CO molar ratio of the humidified syngas may be adjusted in response to time-varying downstream syngas requirements by changing the amount and/or temperature of the diluent that is combined with the raw syngas stream, by adjusting quench and heat exchange conditions, or a combination thereof. The application of the process to the coproduction of chemicals and power are also disclosed. |
