Patent ID: 7030166

Claim:
A Fischer-Tropsch synthesis comprising the steps of: (a) feeding synthesis gas into a first slurry FTR and recovering a first effluent comprised of C 4+ hydrocarbons, water and unreacted syngas; (b) separating the unreacted syngas from the first effluent and feeding the unreacted syngas to a second slurry FTR; (c) withdrawing a second slurry portion from the second FTR slurry and transferring the portion to a first transfer vessel; (d) increasing the pressure of the second slurry portion in the first transfer vessel by feeding a motive gas to the transfer vessel wherein the motive gas has a pressure greater than the second FTR; (e) feeding the second slurry portion from the first transfer vessel into the first FTR; and (f) withdrawing a first slurry portion from the first FTR.
