10~20×10⁴m³ / D Chomera Chopanga Madzi cha LNG Chopangidwa Mwapadera

Mtundu wa LNG

a) Kapangidwe kake

LNG / LCBM ndi chisakanizo cha hydrocarbon ndi methane monga gawo lalikulu, lomwe lili ndi ethane, propane, nayitrogeni ndi zinthu zina zomwe nthawi zambiri zimapezeka mu mpweya wachilengedwe.

Kawirikawiri, kuchuluka kwa methane mu LNG / LCBM kuli kokwera kuposa 80% ndipo kuchuluka kwa nayitrogeni kuli kotsika kuposa 3%.

Ngakhale kuti gawo lalikulu la LNG ndi methane, mphamvu zakuthupi ndi zamakemikolo za LNG sizingadziwike kuchokera ku methane yoyera.

Kapangidwe ka thupi ndi ka thermodynamic ka methane ndi zigawo zina za gasi wachilengedwe kangapezeke m'mabuku ofunikira komanso m'mabuku owerengera a thermodynamic.

b) Kuchulukana

Kuchuluka kwa LNG / LCBM kumadalira zigawo zake, nthawi zambiri pakati pa 430kg / m3 ndi 470kg / m3, koma nthawi zina kumatha kufika 520kg / m3. Kuchulukana kumadaliranso kutentha kwa madzi, ndipo kusintha kwake kumakhala pafupifupi 1.35kg/m3. ℃.

Zipangizo za fakitale ya LNG

1) Dongosolo lalikulu la njira yopangira makina opangira makina a LNG / LCBM:

Kusefera mpweya ndi makina opondereza chakudya

Dongosolo lochepetsa asidi m'mpweya wodyetsa

Dongosolo lowumitsa mpweya wodyetsa chakudya

Dongosolo lochotsera mpweya wolemera wa hydrocarbon

Kuchotsa ndi kusefa mpweya wa mercury

Dongosolo loyeretsera mpweya wochepa kutentha

Kusungira ndi mayendedwe a LNG ndi makina opondereza matope

Makina akuluakulu oziziritsira ndi/kapena makina othandizira oziziritsira

Dongosolo lothandizira pa chitetezo

Dongosolo lowongolera zida ndi zamagetsi

2) Kapangidwe ka dongosolo lothandizira la makina othandizira a LNG / LCBM:

Dongosolo lozungulira madzi ozizira

Nthunzi ndi/kapena makina a madzi otentha

Dongosolo la mpweya wa zida

Dongosolo la nayitrogeni

Makina a gasi kapena / ndi makina a mafuta
