Hunhu hweLNG
a) Kuumbwa
LNG / LCBM musanganiswa wehydrocarbon une methane sechikamu chikuru, une huwandu hushoma hwe ethane, propane, nitrogen nezvimwe zvinhu zvinowanzo kuwanikwa mugasi rechisikigo.
Kazhinji, huwandu hwemethane hweLNG / LCBM hwakakwira kupfuura 80% uye huwandu hwenitrogen hwakaderera pane 3%.
Kunyangwe chikamu chikuru cheLNG chiri methane, hunhu hwepanyama uye hwemakemikari hweLNG hahugone kunzwisiswa kubva kumethane yakachena.
Hunhu hwemuviri uye hwekupisa hwemethane nezvimwe zvikamu zvegasi rechisikigo zvinogona kuwanikwa mumabhuku ekutarisa akakodzera uye mumabhuku ekuverenga ekupisa.
b) Kuwanda kwehuwandu
Kuwanda kweLNG / LCBM kunoenderana nezvikamu zvayo, kazhinji pakati pe430kg / m3 ne470kg / m3, asi mune dzimwe nguva inogona kusvika pa520kg / m3. Kuwanda kwesimba kunoenderanawo nekupisa kwemvura, uye kuchinja kwayo kuri pa1.35kg/m3. ℃.
Zvishandiso zvechigadzirwa cheLNG
1) Main process system main system inoumbwa neLNG / LCBM plant:
Kudyisa gasi rekusefa uye kudzvanya system
Sisitimu yekubvisa acidity yegesi inodyisa
Sisitimu yekuomesa gasi yekudya
Sisitimu yekubvisa mahydrocarbon anorema mugasi
Kubviswa kweMercury uye sisitimu yekusefa gasi rekudyisa
Sisitimu yekunyungudutsa mvura inodziya negasi rakacheneswa
Kuchengetera nekutakura LNG uye sisitimu yekumanikidza bog
Sisitimu huru yekutonhodza uye/kana sisitimu yekuwedzera yekutonhodza
Sisitimu yekubatsira pakuchengetedza
Sisitimu yekudzora zvishandiso zvemagetsi nemagetsi
2) Kuumbwa kwesystem yekubatsira yeLNG / LCBM plant assistant system:
Sisitimu yemvura inotonhorera inotenderera
Sisitimu yemvura inopisa uye/kana yemhepo inopisa
Sisitimu yemhepo yezviridzwa
Sisitimu yeNitrogen
Sisitimu yemafuta kana / uye sisitimu yemafuta emafuta
