Process of enhancing the operating efficiency of a multi-oven ammoniasynthesizing system

Claim 1

THE PROCESS OF SYNTHESIZING AMMONIA IN A CLOSED ALONFATED RING-TYPE SYNTHESIZING SYSTEM INCLUDING A PLURALITY OF OVENS CONNECTED TO SAID SYSTEM AND IN THE PARALLEL WITH ONE ANOTHER AT RESPECTIVE LOCATIONS SPCED LONGITUDINALLY OF SAID SYSTEM, COMPRISING THE STEPS OF INTRODUCING A GAS MIXTURE CONTAINING HYDROIGEN, NITROGEN AND INERT GASES AS COMPONENTS INTO THE INLET PART OF SAID SYSTEM SO THAT THE CONCENTRATION OF SAID INERT GASES IN SAID MIXYURE IS MINIUM IN THE FIRST OVENS, CIRCULATING SAID MIXTURE THROUGH SAID SYSTEM AND SAID OVENS, WHEREBY AMMONIA IS SYNTHESIZED AND THE CONCENTRATION OF SAID INERT GASES INCREASED AT OTHER OVENS SUBSEQUENT TO SAID FIRST OVENS AND WHEREBY A STOICHIOMETRIC DEFICIENCY DEVELOPS IN ONE OF SAID GASES SELECTED FROM THE GROUP CONSISTING OF HYDROGEN AND NITROGEN, AND INTRODUCING INTO THE LAST OVEN OF SAID SYSTEMN A PREDETERMINED QUANTITY OF ONE GAS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN AND NITROGEN, TO THEREBY SUPPLEMENT THE QUANTITY OF THE DEFICIENT ONE SAID HYDROGEN AND NITROGEN COMPONENTS OF SAID MIXTURE SO AS TO REGULATE THE HYDROGEN-NITROGEN RATIO THEREOF.
