  • METHOD AND APPARATUS FOR COMPRESSION OF AMMONIA SYNTHESIS GAS AND RECYCLE GAS FOR THE PRODUCTION OF AMMONIA BY SCREW COMPRESSORS
    Publication number: 20190112197
    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.
    Type: Application
