Method of producing liquid hydrocarbons from a syngas

A method of producing liquid hydrocarbons from a syngas, the method comprising:

• providing a hydrogen-cyanide-containing syngas;
• dividing the hydrogen-cyanide-containing syngas into a first syngas portion and a second syngas portion;
• passing a mixture of the first syngas portion and steam through a water-gas-shift reaction chamber to provide a hydrogen-enriched first syngas portion;
• combining the hydrogen-enriched first syngas portion with the second syngas portion to provide a combined syngas;
• passing the combined syngas through a first hydrolysis reaction chamber to convert at least a portion of the hydrogen cyanide in the combined syngas to ammonia to provide a first ammonia-enriched, hydrogen-cyanide-depleted syngas;
• passing the first ammonia-enriched, hydrogen-cyanide-depleted syngas to a first scrubber and contacting the first ammonia-enriched, hydrogen-cyanide-depleted syngas with a first scrubbing liquid, whereby at least a portion of the ammonia contained in the first ammonia-enriched, hydrogen-cyanide-depleted syngas is retained in the first scrubbing liquid to form a first ammonia-depleted, hydrogen-cyanide-depleted syngas;
• passing the first ammonia-depleted, hydrogen-cyanide-depleted syngas through a carbon dioxide removal unit to form a carbon dioxide-depleted syngas;
• passing the carbon dioxide-depleted syngas to a second hydrolysis reaction chamber to convert at least a portion of the hydrogen cyanide in the carbon-dioxide-depleted syngas to ammonia to provide a second ammonia-enriched, hydrogen-cyanide-depleted syngas;
• passing the second ammonia-enriched, hydrogen-cyanide-depleted syngas to a second scrubber and contacting the second ammonia-enriched, hydrogen-cyanide-depleted syngas with a second scrubbing liquid, whereby at least a portion of ammonia contained in the second ammonia-enriched, hydrogen-cyanide-depleted syngas is retained in the second scrubbing liquid to form a second ammonia-depleted, hydrogen-cyanide-depleted syngas;
• and
• passing the second ammonia-depleted, hydrogen-cyanide-depleted syngas through a Fischer-Tropsch reaction chamber to produce a liquid hydrocarbon product.
