Abstract
Pentane (or similar light hydrocarbon) is used in a gas conversion process to consume the exothermic heat of reaction in the Fischer-Tropsch process, and expanded to produce the energy to drive the air plant compressors.
Claims9
A method for removing heat from a slurry Fischer-Tropsch hydrocarbon synthesis process reaction zone which comprises passing a cooling medium comprising a C.sub.4 -C.sub.10 normal, iso- or cyclic paraffin liquid in cooling tubes in indirect heat exchange through the slurry reaction zone, thereby vaporizing the cooling medium at its boiling point, the cooling medium being inert for Fischer-Tropsch processes, condensible, and vaporizing at a pressure greater than the pressure in the reaction zone, and recovering the vaporized cooling medium neat.
