Chimiro cheLNG
a) Kuumbwa
LNG / LCBM musanganiswa wehydrocarbon ine methane sechinhu chikuru, icho chine huwandu hushoma hweethane, propane, nitrogen uye zvimwe zvikamu zvinowanzovapo mugasi rechisikigo.
Kazhinji kutaura, methane yemukati yeLNG / LCBM yakakwira kupfuura 80% uye iyo nitrogen yemukati yakaderera pane 3%.
Kunyange zvazvo chikamu chikuru cheLNG chiri methane, chimiro chemuviri nemakemikari eLNG hachigone kutorwa kubva kune yakachena methane.
Iyo yemuviri uye thermodynamic zvimiro zvemethane uye zvimwe zvinhu zvegasi rechisikigo zvinogona kuwanikwa mumabhuku ereferensi akakodzera uye thermodynamic calculation manual.
b) Kuwanda
Kuwanda kweLNG / LCBM kunoenderana nezvikamu zvayo, kazhinji pakati pe430kg / m3 uye 470kg / m3, asi mune dzimwe nguva inogona kusvika 520kg / m3. Density ibasa re tembiricha yemvura, uye kusiyanisa kwayo kunosvika 1.35kg/m3. ℃.
Zvishandiso zveLNG chirimwa
1) Main process system main system kuumbwa kweLNG / LCBM chirimwa:
Feed gasi kusefa uye compression system
Feed gasi deacidification system
Feed gasi drying system
Kudyisa gasi rinorema hydrocarbon kubvisa system
Mercury kubviswa uye filtration system yefeed gasi
Yakanatswa gasi yakaderera tembiricha liquefaction system
LNG kuchengetedza uye yekufambisa uye bog compression system
Main firiji system uye / kana yekubatsira firiji system
Chengetedzo yekuyamura system
Instrument uye magetsi control system
2) Yekubatsira sisitimu yekuumbwa kweLNG / LCBM chirimwa chekubatsira system:
Kutenderera kutonhora kwemvura system
Steam uye / kana mvura inopisa system
Instrument air system
Nitrogen system
Fuel gasi system kana / uye mafuta emafuta system
