Okuzenzakalelayo ukusatshalaliswa gas esiteshini

GRS - ukusatshalaliswa esiteshini unikezwe imishini evumela ukwehlisa ingcindezi gas enikeziwe kunethiwekhi backbone ezingeni oyifunayo. Ngaphezu kwalokho, umsebenzi esiteshini kuhlanganisa ukuhlunga odorization, ukusatshalaliswa futhi ukugcina igesi yokuqothulwa.

aphoyintimenti

Negesi ukusatshalaliswa esiteshini iyona into yokugcina uchungechunge uhlelo igesi ukuwudlulisa ngesikhathi esifanayo isakhiwo ikhanda ngoba ezisemadolobheni igesi ompompi. Njengoba ekunqanyulweni supply igesi emadolobheni kanye nezinkampani ezinkulu ezimbonini GDS engamukeleki inikezwa izinto zokuzivikela. Ngaphezu kwalokho, izinto zokuzivikela senziwa isimiso komsebenzi. Umugqa isipele icushiwe lapho awahlelanga main umugqa ukunciphisa.

GDS yakhelwe:

• ethola igesi kusukela main igesi amapayipi;
• wahlanza ke kusukela ukungcola ahlukahlukene ngemishini;
• Decompression kuya namagugu adingekayo kumasistimu ezisemadolobheni;
• nokugcina ingcindezi ezingeni njalo;
• odorizing igesi bafudumale;
• ukuzimisela ngezindleko zayo.

izinhlobo iziteshi

GDS futhi ezenzakalelayo ukusatshalaliswa gas esiteshini ezihlukaniswe injongo yabo:

• Ezenzekelayo ngomhlaka amagatsha main igesi amapayipi - ukuqinisekisa ukuthi igesi zasemizaneni encane. Ngaphezu kwalokho ihlukaniswe ukulawula igesi amaphuzu (1000-30000 Nm ³ / h) futhi uhlelo lokulawula igesi (kufika ku 1500 m ³ / h).
• NeKwakha tekusabalalisa - okuphakelayo umkhakha nengqalasizinda yasemakhaya, amapayipi indandatho nemizana emhlabeni enkulu nemizana 2000-12000 m ³ / h).
• Kuvuna GRS - efakwe izinkambu igesi, by ukuhlanzwa we ekhishwe impahla eluhlaza kusuka umswakama kanye ukungcola.
• Ukuphela iziteshi - zakhelwe ngokuqondile abathengi (amabhizinisi, imiphakathi).

ezishintshayo

Eminyakeni yamuva, kusetshenziswa kakhulu ezizenzakalelayo ukusatshalaliswa gas esiteshini. AGDS amandla 200,000 m ³ / h usebenze ingagadiwe. Kulokhu, esiteshini inebanga imishini futhi Instrumentation, okuvumela ukuba afeze ukusebenza kwawo kwimodi okuzenzakalelayo.

Ukugcina GDS kwenziwe ukude. I-opharetha iziteshi ukusatshalaliswa igesi, ngokuvamile owawuba ezakhiweni lenhlangano inkonzo, ukuqapha kungenziwa ngisho ekhaya. Uma kwenzeka i umsindo eziphuthumayo kanye amasignali ukukhanya kuthiwa ngobulili izakhiwo kanye amakhaya opharetha, okuyinto zitholakala kude ezingekho ngaphezu 0.5 km kusuka esiteshini elawulwa. GDS inkonzo ukusebenza kuka 200,000 m ³ / h senziwa operation lomkhumbi.

imishini

Negesi ukusatshalaliswa esiteshini oluhlanganisa iqoqo lovumelanako imishini kwezobuchwepheshe:

• nokunqamula kudivayisi itheku;
• izihlungi;
• heater;
• umugqa ekunciphiseni futhi elawula ingcindezi igesi;
• Metering kwedivayisi kwamanethiwekhi engenayo igesi ukugeleza;
• nokunqamula idivayisi ngaleso okukhiphayo.

Njengoba nabalawuli ingcindezi asetshenziswa esiteshini abalawuli RD nenkhulumombiko action hlobo RDU.

umjikelezo zobuchwepheshe

It uthola engenayo ukusatshalaliswa gas esiteshini. Isikimu ukuhamba kwayo kanye ukucutshungulwa uchungechunge kanje:

1. Kusukela wegesi main ukuzihlalela kudivayisi senzeka ekuqaleni bese engena zokuhlunga.
2. Ngemva kwalokho it is injected nokwehla esigabeni sokuqala, kokuba imigqa emibili noma emithathu, enye yazo isipele. Lapho kukhona khona ababili cut-imigqa, intambo eceleni ibalwa ngamaphesenti ayikhulu umthamo, kuyilapho esimweni obuthathu - 50%. Eceleni umugqa lapho wathi wesifunda ingasetshenziswa ukundlula esigabeni sokuqala.
3. Uma ingcindezi itheku 4 MPA GDS, ingcindezi igesi esigabeni sokuqala Sehlile 1-1.2 MPA, futhi esigabeni sesibili ukuba 0.2-0.3 MPA. Ngemva yesibili esiteji igesi ingcindezi uzoba ukubaluleka 0.6-0.7 MPA.

Ukufakwa izihlungi nokulawula ingcindezi

Ukukhethwa ukufakwa isikhala isihlungi incike ingcindezi input bese ukwakheka igesi. Uma esiteshini ukusatshalaliswa othola igesi ezimanzi, izihlungi kumele afakwe ngaphambi 1st ukunciphisa esiteji. Izihlungi kulokhu kuyoba njengesicupho condensate, futhi ukungcola lokukhanda. Ngemva kwalokho, ingxube uthuli condensate ingena amathangi sedimentation. Umkhiqizo sebehlanganisa ithunyelwa ethangini lapho uveza ukudonsa gqwa ukuthekelisa e emathangini avuzayo.

Uma uvo GDS ingcindezi esingaphansi 2 MPA ukusebenza, izihlungi asethwe emva 1st ukunciphisa esiteji. Esimweni isikimu enjalo izihlungi iveza ngokudlula (ukuhlangana dlula umugqa) we esigabeni sokuqala. Izihlungi kuleli cala isethelwe ukucindezela 2.5 MPA. Ngokwandisa ingcindezi gas itheku ka phezu 2.5 MPA, idivayisi Ukunqamula ukuxhuma ngesikhathi umugqa dlula ivaliwe kanye negesi kufakwa ohlwini 1st ukunciphisa esiteji. Ngemva ndima yayo igesi fed esigabeni sesibili, futhi emva kwemizuzu 2 - iphayiphi khulula.

Uma esiteshini ukusatshalaliswa kudinga imishini esikhundleni ukwehlisa umugqa oyinhloko, kanye nekwakha umkhiqizo eziphuthumayo off lo mugqa futhi kokuvula umugqa dlula enikeziwe nedivaysi ezithothene kanye valve ukunciphisa. Ukulungisa igesi ukugeleza rate nokucindezelwa wenziwa Kulokhu ngesandla.

Idivayisi ye-okuzenzakalelayo ukusatshalaliswa gas esiteshini

Okuzenzakalelayo igesi iziteshi ukusatshalaliswa Kuningi ongakwenza eziningana ukuze imishini sakhiwo. Noma kunjalo, kumelwe bonke kucatshangelwe njengoba ingozi hydrate kumiswa umnkantsha ongaphandle Sebawoti zangaphandle ukunciphisa. Ngakho-ke, ebusika esiteshini abasebenzi ukukhonza kufanele unake okukhethekile zezici eshiwo ngenhla. Ukuze uvimbele kumiswa hydrate ku GDS asebenzisa isisi esikhalisa Ukushisa amayunithi.

Ukushisisa inhlangano kuhlanganisa heater kanye kubhayela. Amanzi. kubhayela esuka esitsheni akhethekile, Ukushisa efanele yamanzi kubhayela wenziwa omlilo of igesi yanikezwa GDS futhi adluliselwa uhlelo ukunciphisa. Negesi sikaphalafini apharathasi kubhayela usebenza igesi ingcindezi ongaphakeme. Ukuze avimbele igesi okuphakelayo uya omlilo esithandweni of kubhayela ngesikhathi ingcindezi okweqa komkhawulo obekiwe, kukhona idivayisi yezokuphepha. Ngakho, igesi ukunikezela ingcindezi ngokufaka GDS iqondiswa kuqala ukuhlanza amafilithi, kwase kuba kwabayishumi preheater. I preheater is osuke usushisa kakade igesi yilo hydrate isusiwe. Coming heater, igesi dehumidified ingena Imi-line bese ukuba iphayiphi khulula.

izinyathelo zokuvikeleka

Ukuvimbela ukuqhuma imililo ku GDS ukusungula amayunithi ekhethekile ukuze udlulisele iphunga gas. Lezi zilungiselelo uma zingekho izinhlaka igesi ekhanda odorizing noma degree yayo imikhawulo. Ukufakwa igesi odorization ihlukaniswe bubble, ukuvuza futhi intambo yefilakisi. Laba okuthiwa namanje ahwamukayo.

Automation esiteshini ukusatshalaliswa igesi

Umgomo we operation ye ezenzakalelayo ukusatshalaliswa gas esiteshini nge isevisi emakhaya kanje. Esimeni igesi okukhipha ingcindezi phezu ukubaluleka kuvunyelwe, inzwa luthungatha inani elithile, liyala valve shintsho nge kanyekanye abasebenzi isaziso esiteshini nge umsindo nokukhanya mkhosi, ubekwe isihlangu.

Esimweni lapho kukhona nokwanda yokucindezela igesi kwayo kuleyo ndawo yokuhweba ye SDG 5% okweqa okuzisholo ingcindezi value, inzwa okuhambisanayo is Wakhutshwa. Ngenxa yalokho, ukulawula umphini kwenye izintambo zokusebenza ukunciphisa iqala ukuvala, ngaleyo ndlela kuncishiswe ingcindezi esidayisa igesi. Uma ingcindezi akusho yehle, ngeke usebenze omunye inzwa ukuthi eyoqala langaphandle nakakhulu empompini umqondo kuze ukunqamula i-ngokuphelele zonke ukunciphisa umugqa. Endabeni ekunciphiseni okukhipha ingcindezi ukuze 0,95R, emgqeni eceleni ivulekile.

isimo lobuchwepheshe

Naphezu inkimbinkimbi idivayisi, esiteshini ukusatshalaliswa igesi abadinga ekubuyekezeni. Ukwakhiwa iziteshi ukusatshalaliswa igesi ezimweni eziningi kwenziwe 70s, lapho amapayipi babekwa izinkulungwane amakhilomitha ezivela emikhakheni eSiberia abathengi aseYurophu, futhi kwenziwe mass gasification zasemizaneni namabhizinisi zaseSoviet Union ngaphandle kokuphazanyiswa. Cishe 34% of GDS yayigubha iminyaka engu 30, 37% - engaphezu kwengu-10, ngaphansi kuka-ingxenye eyodwa kwezintathu iziteshi anemisila izakhiwo zesimanje engaphansi kwengu-10. Okwamanje, sixoxe uhlelo olunzulu lobuchwepheshe kabusha imishini nokwenza umsebenzi wokuvuselela izakhiwo iziteshi ukusatshalaliswa igesi.
