Abstract
Process and apparatus for the combined production of ammonia synthesis gas and pure hydrogen. There is withdrawn (at 21) a flow of synthesis gas which is first treated in a permeation unit (24) with the return (at 28) of the non-permeated gas, while the permeate (32)is treated by adsorption (34) (35) (36), which permits producing (in 57) very pure hydrogen. The process has a high energy efficiency.
