Nitrogen dị ọcha

  • Carbon Carried Purification to Nitrogen

    Carbon ebugoro dị ọcha na Nitrogen

    Ụkpụrụ nke ịdị ọcha nke Carbon na-ebu

    Enwere ike iji nchacha nke carbon ebu maka usoro nwere mmetụta hydrogen ma ọ bụ nwee nsogbu na isi iyi hydrogen gas. Nri nitrogen dị ụkọ na-emeghachi omume na oke carbon na oke okpomọkụ iji mepụta CO2. Enwere ike nweta nitrogen dị ọcha dị elu mgbe ị gafesịrị ụlọ elu adsorption nke ogige oxygen decarburized.

  • Hydrogenation Purification to Nitrogen

    Hydrogenation ọcha na Nitrogen

    Ụkpụrụ nke ịdị ọcha Hydrogenation

    A ga-emepụta nitrogen raw nitrogen site na PSA ma ọ bụ nkewa akpụkpọ anụ, ma gwakọta ya na obere hydrogen. Oxygen fọdụrụnụ na-emeghachi omume na hydrogen iji mepụta ikuku mmiri n'ime reactor jupụtara na metal palladium catalyst, ya mere, ọtụtụ n'ime ikuku mmiri na-ejupụta site na igwe oyi gachara, a na-ewepụkwa mmiri condensed site na nkewa mmiri dị elu. Mgbe akpịrị ịkpọ nkụ miri emi na iwepụ uzuzu na igwe nkụ, a na-enweta nitrogen dị ọcha dị elu n'ikpeazụ.

    Site n'ụzọ, The adsorption draya nwere ike ime ka igirigi nke ngwaahịa gas n'okpuru - 70 ℃. Onye nyocha na-enyocha ịdị ọcha nke gas ngwaahịa n'ịntanetị.
