Mkpọpụta ihe na-eme nitrogen

N'ọrụ mmepụta ihe, a na-eji ihe na-emepụta nitrogen eme ihe nke ukwuu n'ọrụ mmanụ ala, gas eke, ígwè, nri, ọgwụ na ụlọ ọrụ eletrọniki. Enwere ike iji ihe nitrogen nke ihe na-emepụta nitrogen mee ihe dị ka gas ngwa ọrụ, kamakwa dị ka ihe eji emepụta ihe na refrigerant, nke bụ ngwa ọha dị mkpa na mmepụta ụlọ ọrụ mmepụta ihe. Usoro nke ihe na-emepụta nitrogen na-ekewa n'ụdị atọ: usoro nkewa ikuku miri emi, usoro nkewa akpụkpọ ahụ na usoro adsorption molecular sieve pressure change adsorption method (PSA).
Usoro nkewa ikuku oyi miri emi bụ iji ụkpụrụ isi mmiri dị iche iche nke oxygen na nitrogen n'ikuku, yana mmepụta nke nitrogen mmiri na oxygen mmiri site na ụkpụrụ nke mkpakọ, friji na obere okpomọkụ distillation ". Usoro a nwere ike imepụta obere okpomọkụ nitrogen mmiri na oxygen mmiri mmiri, nnukwu mmepụta; ihe ọghọm bụ nnukwu itinye ego, nke a na-ejikarị eme ihe na mkpa nitrogen na oxygen na ụlọ ọrụ ígwè na kemịkalụ.
Usoro nkewa akpụkpọ ahụ bụ ikuku dị ka ihe eji arụ ọrụ, n'okpuru ọnọdụ nrụgide ụfọdụ, iji oxygen na nitrogen na akpụkpọ ahụ nwere ọnụego permeability dị iche iche iji mee nkewa oxygen na nitrogen?. Usoro a nwere uru nke nhazi dị mfe, enweghị valvụ mgbanwe, obere olu, wdg, mana n'ihi na ihe mkpuchi ahụ dabere na mbubata, ọnụahịa ugbu a dị oke ọnụ ma ọnụego ntinye dị ala, yabụ a na-ejikarị ya eme ihe maka ebumnuche pụrụ iche nke obere mmiri, dị ka igwe na-eme nitrogen mkpanaka.
Usoro ntinye nrụgide nrụgide molekụla (PSA) bụ ikuku dị ka ihe eji arụ ọrụ, sieve molekụla carbon dị ka ihe na-adọrọ adọrọ, ojiji nke ụkpụrụ ntinye nrụgide, ojiji nke sieve molekụla carbon maka ntinye oxygen na nitrogen na usoro nkewa oxygen na nitrogen ". Usoro a nwere njirimara nke usoro dị mfe, oke akpaghị aka dị elu, obere oriri ike na ịdị ọcha nitrogen dị elu, ọ bụkwa teknụzụ a na-ejikarị eme ihe. Tupu ikuku abanye n'ụlọ elu ntinye mmadụ, a ga-akpọrịrị mmiri dị n'ikuku iji belata mbuze mmiri na sieve molekụla ma gbasaa ndụ ọrụ nke sieve molekụla. Na usoro mmepụta nitrogen PSA nkịtị, a na-ejikarị ụlọ elu nkụ ahụ ewepụ mmiri dị n'ikuku. Mgbe ụlọ elu nkụ jupụtara na mmiri, a na-efegharị ụlọ elu nkụ ahụ na ikuku akọrọ iji mezuo mweghachi nke ụlọ elu nkụ.
