Ukadaulo wa njira zopangira ndi kufotokozera za chomera cha LNG cha 71t/d (2)

2.3      Chipangizo Choumitsira Mpweya Wodyetsa

1) Kufotokozera njira

Mpweya wachilengedwe wochepa asidi umalowa mu chipangizo chowumitsira mpweya wodyetsa chakudyaChipangizochi chimagwiritsa ntchito ukadaulo wokhudza kutentha ndi kusinthasintha kwa mpweya kuti chilekanitse ndikuyeretsa mpweya. Ukadaulo wokhudza kutentha ndi kusinthasintha kwa mpweya umachokera pa kusungunuka kwa mpweya mkati mwa mpweya (porous solid matter), ndipo kusungunuka kwa mpweya ndi mpweya ndi kusungunuka kumagwiritsidwa ntchito. Khalidwe loti mphamvu yake imasiyana malinga ndi kutentha ndi kukakamizidwa kwa mpweya. Ngati mpweya umasungunuka mosankha zigawo zosiyanasiyana za mpweya, zigawo zina mu mpweya wosakanikirana zimasungunuka pa kutentha kochepa komanso kuthamanga kwambiri, ndipo zigawo zosasungunuka zimatuluka kudzera mu gawo la adsorber., zigawo zosungunuka zimachotsedwa pa kutentha kwakukulu komanso kuthamanga kochepa kuti zisungunuke kutentha kochepa komanso kuthamanga kwambiri, ndipo nsanja zingapo zosungunuka zingagwiritsidwe ntchito kukwaniritsa cholinga cholekanitsa mpweya mosalekeza.

Chipangizo chowumitsira mpweya wothira mafuta ndi chochotsera ma hydrocarbon ambiri chili ndi zokoka zitatu zosinthira, chimodzi chokoka madzi, china chokoka madzi ozizira, ndi china chokoka madzi kuti ayambenso kugwira ntchito.

Mpweya wochokera ku chipangizo chochotsera asidi umalowa pamwamba pa adsorber, ndipo chinyezi chikachotsedwa ndi molecular seeve adsorption, chimatuluka pansi pa adsorber. Mpweya wachilengedwe ukatha kulowa mu nsanja yochotsera mercury.

Chipangizo choumitsira mpweya wothira mafuta chimagwiritsa ntchito mpweya wothira mafuta pang'ono ngati njira yoziziritsira ndi kubwezeretsa mpweya. Mpweya wothira mafuta ukatuluka mu nsanja yothira mafuta, umaziziritsidwa ndikulekanitsidwa ndikubwezeredwa kumalo olowera a nsanja yothira mafuta mu mkhalidwe wa kuthira mafuta.

Mpweya wobwezeretsa umadutsa koyamba mu adsorber yozizira kuchokera pamwamba mpaka pansi, kenako mpweya wobwezeretsa umatenthedwa kufika kutentha kwa 180-260 ℃ ndi chotenthetsera chobwezeretsa, kenako umalowa kuchokera pansi pa adsorber kuti uyamwe madzi omwe amatengedwa ndi adsorbent. Mpweya wobwezeretsa umatuluka pamwamba pa choumitsira, ndipo utaziziritsidwa ndi choziziritsira chobwezeretsa, umalowa mu cholekanitsa mpweya wobwezeretsa, ndipo madzi omwe ali mmenemo amalekanitsidwa ndikubwerera kumapeto kwa adsorber.

Madzi mu mpweya wachilengedwe wouma akadutsa mu chipangizochi, amakhala ≤1ppm.

Zipangizo zazikulu ndi nsanja yothira madzi, chotenthetsera madzi chobwezeretsanso, choziziritsira madzi chobwezeretsanso ndi cholekanitsa madzi chobwezeretsanso.

2) Magawo a kapangidwe

Mphamvu yokonza mpweya wodyetsa chakudya:10×10 ⁴ Nm ³ /d

Kuthamanga kwa ntchito: 5.2 Mpa.G

Kutentha kwa madzi: 40 ℃

Kutentha kwa kusinthika: 180 ℃ ~260 ℃

Gwero la kutentha kosinthika: kutentha kwa mafuta osamutsa kutentha

Zomwe zili mu H₂O mu mpweya woyeretsedwa ndi ≤ 1ppm

2.4     Chida chochotsera mpweya wa mercury

1) Kufotokozera njira

Mpweya wachilengedwe ukatha kusungunuka, mpweya wachilengedwe umalowa koyamba mu adsorber ya kaboni yoyambitsidwa ndi sulfure. Mercury imachitapo kanthu ndi sulfure pa kaboni yoyambitsidwa ndi sulfure kuti ipange mercury sulfide, yomwe imasungunuka pa kaboni yoyambitsidwa kuti ikwaniritse cholinga chochotsa mercury. Kuchuluka kwa mercury mu mpweya wachilengedwe wotuluka mu chochotsera mercury ndi kochepera 0.01μg/Nm3.

Chochotsera cha Mercury chimayikidwa, ndipo mpweya woyatsidwa ndi sulfure umasinthidwa malinga ndi momwe zinthu zilili.

Mpweya wachilengedwe wosagwiritsidwa ntchito umalowa mu fyuluta.

2) Magawo a kapangidwe

Mphamvu yokonza mpweya wodyetsa chakudya:10×10 ⁴ Nm ³ /d

Kuthamanga kwa ntchito: 5.0Mpa.G

Kutentha kwa kuyamwa: 40 ℃

Kuchuluka kwa Hg mu mpweya woyeretsedwa ndi ≤ 0.01μg/Nm ³

3) Kuchuluka kwa kusintha: 50% ~ 110%.

2.5    Chigawo Chosefera Mpweya Wodyetsa

1) Kufotokozera njira

Chipangizo chosefera chili ndi fyuluta, yomwe imatha kusinthidwa ndikugwiritsidwa ntchito malinga ndi deta yotsutsa kuti ikwaniritse cholinga chosefera sieve ya molecular ndi fumbi la carbon lomwe layambitsidwa.

Pambuyo pochotsa fumbi, tinthu ta fumbi mu mpweya wodyetsa timachepa kuposa 10 μm.

Zipangizo zazikulu ndi fyuluta ya fumbi.

Mphamvu yokonza mpweya wodyetsa chakudya:10×10 ⁴ Nm ³ /d

2) Magawo a kapangidwe

Kuthamanga kwa ntchito: 5Mpa.G

Fumbi lomwe lili mu mpweya woyeretsedwa ndi ≤ 5μm
