Abstract
A method for producing ammonia may be provided. The method may include supplying ammonia synthesis gas to a synthesis gas screw compressor and compressing the synthesis gas. The compressed synthesis gas may be joined with a flow of recycle gas compressed in a recycle gas screw compressor. The compressed combined flow may then be introduced to an ammonia reactor. The ammonia reactor may discharge ammonia, purge gas, and unconverted gas, which may be the recycle gas.
Claims11
A system for producing ammonia comprising:
- at least one screw compressor;
- and
- an ammonia reactor, wherein the at least one screw compressor compresses at least one of ammonia synthesis gas and recycle gas and supplies a compressed gas flow to the ammonia reactor, and wherein the ammonia reactor discharges produced ammonia, purge gas, and recycle gas.
A method for producing ammonia comprising:
- supplying ammonia synthesis gas to a screw compressor;
- compressing the ammonia synthesis gas in the screw compressor;
- discharging a flow of compressed ammonia synthesis gas;
- combining a flow of compressed recycle gas with the flow of compressed ammonia synthesis gas, forming a compressed combined gas flow;
- supplying the compressed combined gas flow to an ammonia reactor, wherein the ammonia reactor discharges a produced ammonia, purge gas, and recycle gas;
- supplying the recycle gas to a screw compressor;
- compressing the recycle gas;
- and
- supplying the compressed recycle gas to the flow of compressed ammonia synthesis gas.
