1. An apparatus to produce sustainable aviation fuel from dry natural gas, the apparatus comprising:
a natural gas reforming apparatus that receives the dry natural gas and that produces synthetic gas from the dry natural gas;
a Fischer-Tropsch conversion apparatus that is directly and operably coupled to the natural gas reforming apparatus and that receives the synthetic gas and produces a hydrocarbon chain from the synthetic gas, wherein the Fischer-Tropsch conversion apparatus further comprises a membrane separator that is operably coupled to a guard bed that is operably coupled to a Fischer-Tropsch converter being operably coupled to a steam drum, the Fischer-Tropsch converter being operably coupled to a wax trap which is operably coupled to a heat exchanger which is operably coupled to a converter separator that outputs tail gas, the converter separator is also operably coupled to an oil/water cyclone which is operably coupled to a condenser which is operably coupled to a condensate pump which outputs synthetic water, the converter separator and the wax trap are both operably coupled to a wax degasser which is operably coupled to a wax pump which outputs wax; and
a product upgrading apparatus that is operably coupled to the Fischer-Tropsch conversion apparatus that receives the hydrocarbon chain and that produces the sustainable aviation fuel from the hydrocarbon chain, wherein the product upgrading apparatus further comprises a pressure swing adsorption device that is operably coupled to an H2 compressor which is operably coupled to a hydrocracker which is operably coupled to product separation drums, which is operably coupled to a production pump.
