Mpweya wachilengedwe wosungunuka (LNG) ndi mpweya wachilengedwe, makamaka methane, womwe waziziritsidwa kukhala madzi kuti usungidwe mosavuta komanso mosamala. Umatenga pafupifupi 1/600th ya kuchuluka kwa mpweya wachilengedwe mu mpweya.
A chomera chonse chothira madzi a LNG Ili ndi machitidwe atatu: njira yogwirira ntchito, njira yowongolera zida ndi njira yogwiritsira ntchito. Malinga ndi magwero osiyanasiyana a mpweya, imatha kusinthidwa.
Njira yogwiritsira ntchito chomera cha cryogenic LNG ikuphatikizapo:
- Kusefa mpweya wodyetsa, kulekanitsa, malamulo oyendetsera kuthamanga kwa magazi ndi chipangizo choyezera kuthamanga kwa magazi;
- Chipangizo chopatsira mpweya wothira chakudya
- Chipinda chothandizira odwala (kuphatikizapo chipangizo chochotsera asidi m'mpweya, kusowa madzi m'thupi komanso chochotsera madzi ambiri m'thupi, kuchotsa mercury ndi fumbi);
- Gawo lowerengera MR ndi gawo la kuzungulira kwa MR;
- Chipangizo choyeretsera madzi cha LNG (kuphatikizapo chipangizo choyeretsera madzi);
Apa, tikuyambitsa njira yowongolera zida za fakitale ya LNG.
Pofuna kuyang'anira bwino njira yopangira zida zonse, kuonetsetsa kuti zikugwira ntchito modalirika, komanso kuthandizira ntchito ndi kukonza, makina owongolera zida a dongosololi makamaka amaphatikizapo: makina owongolera ogawidwa (DCS), makina otetezera zida (SIS), kuzindikira moto ndi mpweya woyaka ndi makina a alamu (GDS), makina owunikira makanema (CCTV), ndi zida zolondola kwambiri (ma flowmeter, analyzers, kutentha, kuthamanga, kuyenda) zomwe zimakwaniritsa zofunikira pa ndondomekoyi, ndi zina zotero, kupereka ntchito zonse zokonzera, kuyambitsa, ndi kuyang'anira, kuphatikiza deta ya ndondomeko Kupeza, kuwongolera kotsekedwa, kuyang'anira momwe magwiridwe antchito a zida amagwirira ntchito, unyolo wa alamu ndi ntchito, kukonza ndi kuwonetsa deta nthawi yeniyeni, ntchito yoyendera, kuwonetsa zithunzi, ntchito yolemba zolemba za ntchito ndi ntchito zina. Pakakhala vuto pa chipangizo chopangira, kapena makina a GDS akatumiza chizindikiro cha alamu, SIS idzatumiza chizindikiro choteteza kuti chiteteze zida zomwe zili pamalopo, ndipo makina a GDS adzadziwitsa dipatimenti yozimitsa moto yapafupi nthawi yomweyo.
Zipangizo zonse zowongolera zomwe ziyenera kuyikidwa pamalo oopsa zimakwaniritsa zofunikira za mulingo wa malo oopsa komanso chitetezo chonse, ndipo kapangidwe ndi kusankha kumatsatira miyezo ndi miyezo yoyenera yadziko.
Kuphatikiza apo, makina owongolera zida zonse m'dera la process unit amayendetsedwa ndi PLC yodziyimira payokha, ndipo zizindikiro zake zofunika zimatumizidwa ku DCS m'chipinda chowongolera chapakati kuti ziwonetsedwe kudzera mu kulumikizana pakati pa makina, ndipo imalumikizidwa ndi makina otetezera zida (SIS) pogwiritsa ntchito mawaya olimba.
Dongosolo lowongolera zida (gawo la ndondomeko) lili ndi magawo otsatirawa:
★ Dongosolo Lolamulira Logawidwa (DCS) : DCS ndiye maziko ndi pakati pa makina owongolera zida, omwe amapereka chiwonetsero, magwiridwe antchito ndi kuwongolera magawo onse a machitidwe ndi ma alamu, ndipo ali ndi kuthekera kolumikizana ndi makina ena.
★ Dongosolo Loteteza Zida (SIS) : Ndi gawo la chitetezo cha makina, chomwe chimagwiritsidwa ntchito makamaka pa chitetezo cha zida pakagwa ngozi, malinga ndi dongosolo lokonzekera magalimoto, losadalira kapangidwe ka DCS, komanso lotetezeka kwambiri kuposa DCS.
★ Mphamvu yamagetsi yosasinthika (UPS) : Monga gawo la kudalirika kwa makina, imatha kupereka mphamvu yogwirira ntchito kwa nthawi inayake ngati magetsi alephera mwadzidzidzi kuti atsimikizire kuzimitsa kwa ntchito ndi chithandizo chadzidzidzi.
★ Chida choyezera njira : gawo lofunikira la parameterization ya dongosolo, lomwe limapangidwa ndi zida zingapo zoyezera ndi masensa, omwe kulondola kwawo ndi kulondola kwawo kumakhudza mwachindunji kuwongolera parameterization ya dongosolo.
★ Valavu yowongolera : gawo losinthira ndi kuchitapo kanthu pa magawo a ndondomeko.
★ Chowunikira pa intaneti : Imakhala ndi zida zina zowunikira zigawo, zomwe ndi zowonjezera pazida zoyezera ndipo zimapereka maziko ogwirira ntchito powongolera njira.
