Summary

MOST PROCESS IMPROVEMENT HAS LED TO MORE COMPLEX SYSTEMS WITH A GREATER RISK OF FAILURE. HERE PROCESS STAGES OF PROVEN RELIABILITY ONLY WERE TO BE USED. WITH NATURAL GAS AS FEED-STOCK, THE NEW SYSTEM TAKES IN ENRICHED AIR FROM A SEPARATION PLANT, FEEDING THE NITROGEN COMPONENT DIRECTLY INTO THE COMPRESSOR. THE GAS UNDERGOES DESULPHURIZATION, THEN HIGH TEMPERATURE CO CONVERSION, AND THEN ENTERS A PRESSURE-SWING ADSORPTION UNIT WHICH IS THE MAJOR DIFFERENCE TO CONVENTIONAL SYSTEMS. THE OUTLET FROM THIS JOINS WITH THE NITROGEN AT COMPRESSOR INLET AND IS DELIVERED TO THE AMMONIA SYNTHESIS PROCESS. D.W.H.
