1. Pali zinthu zitatu zomwe mungachite ngati mphamvu ya nayitrogeni ikukwera kuposa 8bar:

Yankho loyamba: njira yopangira nayitrogeni yowonjezera mmbuyo imakhala ndi kompresa ya nayitrogeni nthawi imodzi.Kumapeto kwa chowonjezera kumakakamiza mankhwala a nayitrogeni kapena mpweya wakutsogolo.Kuthamanga kwa kompresa ya mpweya ndiye kutsika kotsika kwambiri kwa kubweza kwa m'mbuyo, ndipo kuchuluka kwa zotulutsa kumatha kufika 38%.za.

Yachiwiri njira: zabwino otaya Kukula nayitrogeni kupanga ndondomeko okonzeka ndi mankhwala nayitrogeni kompresa pa nthawi yomweyo, chilimbikitso mapeto a expander pressurizes mankhwala asafe kapena mpweya wabwino otaya, osachepera distillation nsanja kuthamanga ndi 4bar, mlingo mankhwala m'zigawo imatha kufika pafupifupi 45%, ndipo kuchuluka kwamadzimadzi kumatha kutulutsa zazikulu.

Njira yachitatu: njira yowonjezera yobwerera m'mbuyo, nitrogen mankhwala opangidwa ndi nayitrogeni kapena mpweya wabwino womwe umayenda kumapeto kwa chowonjezera, kukakamiza kofunikira kwa chinthucho kuchokera mubokosi lozizira, choyipa ndichakuti kuthamanga kwa backflow ndikokwera kwambiri, kumayambitsa mbali ya mphamvu yogwira ntchito yosagwiritsidwa ntchito.

2. Pali njira ziwiri zopangira nayitrogeni wapakati pa 5 ndi 8 bar:

Yankho loyamba: njira yokulirapo yobwerera m'mbuyo, nayitrogeni wa mankhwala kapena mpweya wapatsogolo amapanikizidwa kumapeto kwa chilimbikitso cha chowonjezera.

Yankho lachiwiri: njira yabwino yowonjezeretsa otaya, mapeto chilimbikitso cha expander pressurizes mankhwala asafe kapena mpweya wabwino otaya, ndipo mankhwala wothinikizidwa ndi nayitrogeni kompresa.Njirayi ili ndi ubwino waukulu pamene kupanikizika kuli kwakukulu.

3. Pali njira zinayi zopangira nayitrogeni pa 0 mpaka 5 bar:

Yankho loyamba: ndondomeko yowonjezera backflow, mapeto a chilimbikitso cha expander pressurizes mankhwala nayitrogeni kapena mpweya kutsogolo, ndiyeno throttles kuti kuthamanga chofunika, zambiri 4 kuti 5bar;kupanikizika kwa backflow kufutukula mpweya kompresa ndi apamwamba kuposa kukakamiza mankhwala asafe 0.8bar mkulu chofunika.

Yankho lachiwiri: njira yabwino yowonjezeretsera, mpweya wa nayitrogeni kapena mpweya wabwino umakanikizidwa kumapeto kwa chilimbikitso, ndipo kukakamiza kwazinthu kumapezeka mwachindunji, ndipo nayitrogeni wamba ndi 4bar mpaka 5bar.Kuthamanga kwa kompresa yowonjezera yoyenda bwino ndi pafupifupi 1.5bar kuposa mankhwala a nayitrogeni, koma kuchuluka kwake m'zigawo ndikwambiri.Mpweya wotambasulidwa umayamba kukakamizidwa, kenako kukulitsidwa, kenako ndikutuluka mwachindunji ngati mpweya wosinthika;pamene mlingo wa mankhwala uli waukulu kuposa 10000Nm³/h, chowonjezera chosiyana chitha kukhazikitsidwa Kuti mutsegule mpweya wowonjezera, lowetsani nsanjayo mukakulitsa, zomwe zitha kuwonjezera kuchuluka kwazinthu.

Njira yachitatu: njira yokonzanso nsanja ziwiri.Njirayi imagwiritsa ntchito mpweya wochuluka wa okosijeni pakati pa nsanja yapamwamba monga mpweya wotayira kuti utulutsidwe kwa oyeretsa ngati mpweya wokonzanso, ndipo mpweya wambiri wochuluka wa okosijeni pansi pa nsanja yapamwamba umachotsedwa ngati mpweya wosakhala wa mankhwala, zomwe zimatha kuwonjezera kuthamanga kwa kutulutsa kwa nsanja yapamwamba., Kukumana mankhwala nayitrogeni kuthamanga zofunika, kupulumutsa mowa nayitrogeni mankhwala psinjika.Njirayi imatha kupeza nayitrogeni wazinthu pamitsempha iwiri ya 0 mpaka 2 bar ndi 5 bar kapena kupitilira apo.

Yankho lachinayi: njira ziwiri zochepetsera nsanja ziwiri, kugwedeza mpweya pansi pa nsanja yapamwamba, ndiyeno pitani kumutu wa condensation pamwamba pa nsanja, kuti mupeze 0 mpaka 3 bar ndi 5 mpaka 7. bar kapena apamwamba mankhwala asafe, mlingo mankhwala m'zigawo za ndondomeko Mkulu, mpaka 60%.
