Abstract:
A method for producing ammonia using a hydrocarbon containing formation, comprising:generating a first ammonia feed stream from a first portion of the formation; generating a second ammonia feed stream from a second portion of the formation, wherein the second ammonia feed stream has a H2 to N2 ratio greater than a H2 to N2 ratio of the first ammonia feed stream; blending at least a portion of the first ammonia feed stream with at least a portion of the second ammonia feed stream to produce a blended ammonia feed stream having a selected H2 to N2 molar ratio; providing the blended ammonia feed stream to an ammonia synthesis process; and using the ammonia synthesis process to generate ammonia.
