Embodiment 1
[0024] a. The first stage of desulfurization is crude hydrogen sulfide desulfurization, using iron oxide desulfurizer at room temperature. 2 Hydrogen sulfide sulfur in the effluent of S reactor ≥ 10μg·g -1 When switching to the spare reactor, heat the original reactor to 80°C and ventilate naturally to regenerate the iron oxide desulfurizer at room temperature;
[0025] b. The natural gas that has been crudely dehydrogenated in the first stage enters the second-stage fine hydrogen sulfide removal reactor, using normal temperature zinc oxide desulfurizer. 2 Hydrogen sulfide sulfur in the effluent of S reactor ≥ 0.1μg·g -1 Switch to the spare reactor when the time comes, and replace the original reactor with a new room temperature zinc oxide desulfurizer;
[0026] c. The natural gas that has undergone the second-stage fine-removal of hydrogen sulfide enters the third-stage fine-removal organic sulfur reactor, using normal temperature NaX molecular sieve desulfurizer, when the ...
