Kuyerekeza magwero a nayitrogeni kwa opanga nayitrogeni
Nayitrogeni yamadzimadzi ndi chinthu chomwe chimachokera ku kulekanitsidwa kwa mpweya wa cryogenic Kupanga kwa Nayitrogeni. Pansi pa mikhalidwe yokhazikika, 1m3 ya nayitrogeni yamadzimadzi imatha kusinthidwa kukhala 643m3 ya nayitrogeni, koma kuchuluka kwenikweni komwe kumagwiritsidwa ntchito nthawi zambiri kumakhala pafupifupi 95%, ndiko kuti, 1m3 ya nayitrogeni yamadzimadzi imatha kugwiritsa ntchito pafupifupi 610m3 ya nayitrogeni. Pakadali pano, mtengo wapakati pamsika wa nayitrogeni yamadzimadzi ndi pafupifupi 1,000 yuan/m3, ndipo mtengo wa unit wa nayitrogeni ndi 1.67 yuan/m3. Pogwiritsa ntchito nayitrogeni yamadzimadzi, ogwiritsa ntchito ayenera kukhala ndi matanki osungira nayitrogeni yamadzimadzi, ma gasifiers ofanana ndi kuchuluka kwa madzi, ndi ma valve olamulira kuthamanga komwe kumafanana ndi kuthamanga, zomwe ndizofunikira ndalama zoyambira.
Kupatula mpweya wolekanitsa kupanga nayitrogeni ndi nthambi yatsopano yopanga nayitrogeni yosagwiritsa ntchito cryogenic. Ndi njira yatsopano yopanga nayitrogeni yomwe yakula mofulumira kunja kwa dziko m'zaka za m'ma 1980. Imagwiritsa ntchito mpweya ngati zopangira ndipo imagwiritsa ntchito kuchuluka kosiyanasiyana kwa mpweya ndi nayitrogeni m'maselo opanda ulusi pansi pa kukakamizidwa kwina kuti ilekanitse mpweya ndi nayitrogeni kuti ipange nayitrogeni. Poyerekeza ndi njira ziwiri zomwe zili pamwambapa zopangira nayitrogeni, ili ndi mawonekedwe osavuta a zida, kukula kochepa, ma valve osasinthira, kugwiritsa ntchito mosavuta ndi kukonza, kupanga mpweya mwachangu (mkati mwa mphindi zitatu), komanso kukula kosavuta kwa mphamvu.
