1. prepare the method for high-purity ammon under the utmost point low pressure condition, comprise the steps:

  • 1) get high-purity hydrogen nitrogen unstripped gas, hydrogen nitrogen material purity reaches 99.999%~

    99.9999999%;

    2) high-purity hydrogen nitrogen unstripped gas is transported to synthetic high-purity ammon in the synthetic ammonia tower;

    Hydrogen in the described hydrogen nitrogen mixed gas and the mol ratio of nitrogen are 3;

    1;

    It is characterized in that;

    described step

         2), pressure condition is 4~

    7MPa, and temperature condition is 300~

    400 ℃

    ;

    Catalyzer adopts at 200~

    400 ℃

    of catalyzer with good activity.
