1. Muaj peb txoj kev xaiv thaum cov khoom nitrogen siab siab tshaj 8bar:

Thawj qhov kev daws teeb meem: cov txheej txheem rov qab nthuav dav nitrogen ntau lawm yog nruab nrog cov khoom siv nitrogen compressor tib lub sijhawm.Qhov kawg ntawm lub expander pressurizes cov khoom nitrogen los yog rau pem hauv ntej cua.Cov cua compressor siab yog qhov qis tshaj qhov rov qab nthuav dav siab, thiab cov khoom rho tawm tuaj yeem ncav cuag 38%.txog.

Qhov thib ob kev daws teeb meem: qhov zoo txaus nthuav dav nitrogen cov txheej txheem tsim khoom yog nruab nrog cov khoom siv nitrogen compressor tib lub sijhawm, lub zog kawg ntawm lub expander pressurizes cov khoom nitrogen los yog zoo txaus cua, qhov tsawg kawg nkaus distillation ntauwd siab yog 4bar, cov khoom rho tawm tus nqi tuaj yeem ncav cuag li 45%, thiab cov kua dej tuaj yeem tsim loj dua.

Qhov kev xaiv thib peb: cov txheej txheem rov qab nthuav dav, cov khoom lag luam siab nitrogen lossis cov huab cua zoo ntws ntawm qhov kawg ntawm lub expander, lub siab xav tau rau cov khoom ncaj qha tawm ntawm lub thawv txias, qhov tsis zoo yog qhov backflow expansion siab, ua rau ib feem ntawm lub zog siv tau zoo yuav tsum tsis txhob siv.

2. Muaj ob txoj kev xaiv thaum cov khoom nitrogen nyob nruab nrab ntawm 5 thiab 8 bar:

Thawj qhov kev daws teeb meem: cov txheej txheem rov qab rov qab nthuav dav, cov khoom lag luam nitrogen lossis huab cua rau pem hauv ntej yog pressurized ntawm qhov kawg ntawm lub expander.

Qhov thib ob kev daws teeb meem: cov txheej txheem zoo ntws nthuav dav, qhov kawg ntawm lub expander pressurizes cov khoom nitrogen los yog zoo txaus cua, thiab cov khoom yog compressed los ntawm ib tug nitrogen compressor.Cov txheej txheem no muaj txiaj ntsig zoo thaum lub siab siab.

3. Muaj plaub txoj kev xaiv rau cov khoom nitrogen ntawm 0 mus rau 5 bar:

Thawj qhov kev daws teeb meem: cov txheej txheem rov qab rov qab nthuav dav, qhov kawg ntawm qhov nthuav dav pressurizes cov khoom nitrogen los yog cua rau pem hauv ntej, thiab ces throttles mus rau qhov xav tau siab, feem ntau 4 mus rau 5bar;Lub siab ntawm lub backflow expansion cua compressor yog siab tshaj qhov siab ntawm cov khoom nitrogen 0.8bar siab yuav tsum tau.

Qhov thib ob kev daws teeb meem: cov txheej txheem nthuav dav zoo, cov khoom lag luam nitrogen lossis cov huab cua zoo ntws yog siab ntawm qhov kawg ntawm lub expander, thiab cov khoom siab ncaj qha tau txais, thiab cov khoom siv nitrogen yog 4bar rau 5bar.Lub siab ntawm qhov zoo ndlwg expansion compressor yog hais txog 1.5bar siab tshaj cov khoom nitrogen, tab sis nws cov extraction tus nqi siab dua.Cov huab cua nthuav dav yog thawj zaug pressurized, ces nthuav, thiab ces ncaj qha vented li regeneration gas;Thaum cov khoom lag luam loj dua 10000Nm³ / h, ib qho kev sib cais tuaj yeem muab tso rau txhawm rau txhawm rau txhawm rau nthuav dav huab cua, nkag mus rau ntauwd tom qab nthuav dav, uas tuaj yeem ua rau cov khoom ntim ntau ntxiv.

Qhov kev xaiv thib peb: txheej txheem kev kho ob-ntauwd.Cov txheej txheem no siv cov pa oxygen nplua nuj nyob hauv nruab nrab ntawm cov pej thuam saum toj kawg nkaus raws li cov pa tso pa tawm mus rau lub purifier li regeneration gas, thiab ntau cov pa oxygen nplua nuj nyob hauv qab ntawm cov pej thuam sab saud yog muab rho tawm raws li cov khoom siv roj, uas tuaj yeem ua rau kom lub siab tso tawm ntawm cov pej thuam sab saud., Ua tau raws li cov khoom siv nitrogen siab, txuag lub zog noj cov khoom siv nitrogen compression.Cov txheej txheem no tuaj yeem tau txais cov khoom nitrogen ntawm ob lub siab ntawm 0 mus rau 2 bar thiab 5 bar lossis siab dua.

Txoj kev daws plaub: ob chav-tsev ob chav-condensation txheej txheem, throttling cov pa oxygen nyob rau hauv qab ntawm lub sab sauv, thiab ces mus rau lub condensation lub taub hau nyob rau sab saum toj ntawm lub pej thuam, kom koj tau txais 0 mus rau 3 bar thiab 5 mus rau 7. bar lossis siab dua cov khoom nitrogen, cov khoom rho tawm tus nqi ntawm cov txheej txheem no Siab, txog li 60%.
