Integration of FT System and Syn-gas Generation
In some implementations, a method for separating components includes receiving off-gas from a Fischer-Tropsch hydrocarbon synthesis reaction process. The off-gas is scrubbed with a light oil at least proximate atmospheric temperature to substantially remove a mixture of C 3 and C 4 . The C 3 and C 4 are separated from the mixture into two separate streams using distillation columns in a Fischer-Tropsch system.
1 . A method for separating components, comprising:
receiving off-gas from a Fischer-Tropsch (FT) hydrocarbon synthesis reaction process;
scrubbing the off-gas with a light oil at least proximate atmospheric temperature to substantially remove a mixture of C 3 and C 4 ; and
separating C 3 and C 4 from the mixture into two separate streams using distillation columns in a Fischer-Tropsch system.
2 . The method of claim 1 , wherein the light oil includes a product from at least one of FT oil/wax hydro-treating, isomerization, or separation unit.
3 . The method of claim 1 , separating from the off-gas substantially all CO 2 produced during the FT process.
