The GTL process of the invention comprises: reacting a combustible carbonaceous material in a syngas reactor, preferably an autothermal reformer, under conditions to produce a synthesis gas; contacting the synthesis gas with an F-T catalyst to form liquid products and a tail gas; separating the tail gas from the liquid products; separating COfrom the light products in the tail gas; recovering the light products as additional products for sale or other use and utilizing at least a portion of the separated COas a feed stream to the syngas reactor.

Light ends recovery process for a GTL plant

This invention relates to a process for liquefying a gas stream rich in methane and having a pressure above about 3103 kPa (450 psia). The gas stream is expanded to a lower pressure to produce a gas phase and a liquid product having a temperature above about -112.degree. C. (-170.degree. F.) and a pressure sufficient for the liquid product to be at or below its bubble point. The gas phase and the liquid product are then phase separated in a suitable separator, and the liquid product is introduced to a storage means for storage at a temperature above about -112.degree. C. (-170.degree. F.).

Process for liquefaction of natural gas

This invention relates to a process for liquefying a pressurized gas stream rich in methane in which the liquefication of the gas stream occurs in a heat exchanger being cooled by a closed-loop multi-component refrigeration system to produce a methane-rich liquid product having a temperature above about -112.degree. C. (-170.degree. F.) and a pressure sufficient for the liquid product to be at or below its bubble point. The liquefied gas product is then introduced to a storage means at a temperature above about -112.degree. C. (-170.degree. F.).
