Ngokwayo station distribution igesi

station lonikezelo banikwa izixhobo evumela ukuba azole ukuhlisa uxinzelelo berhasi anikezelweyo ukusuka kuthungelwano ngumqolo ukuya kwinqanaba elifunekayo - GRS. Ukongeza, isikhululo umsebenzi iquka nocococ kunye odorization, usasazo kunye nokugcina irhasi osetyenzisiweyo.

ukuqashwa

station lokuhambisa igesi ke into wokugqibela chain kwenkqubo transmission igesi kwakunye ngexesha elifanayo isakhiwo intloko kwiinkqubo igesi ezidolophini. Ekubeni inqanyulwe igesi kwizixeko kunye neenkampani ezinkulu mveliso engamkelekanga GDS inikwa izixhobo zokhuselo. Ngaphezu koko, lo izixhobo senziwe kumgaqo komsebenzi. Umgca oncedo izingenele xa kuphuma umyalelo ekunciphiseni umzila.

GDS iyilelwe oku:

• abafumana igesi evela lwemibhobho main igesi;
• ukusisulungekisa ubumdaka ezahlukeneyo mechanical;
• Decompression ukuya nokuxabisekileyo okufunekayo kwiinkqubo nasezidolophini;
• nokugcina uxinzelelo kwinqanaba njalo;
• odorizing gas ubushushu;
• yokuqingqwa ngeendleko zayo.

iintlobo kwizikhululo

GDS ngokwayo station distribution igesi singahlukaniswa injongo yabo;

• Oluzenzekelayo amasebe lwemibhobho yegesi engundoqo - ukuqinisekisa ukuba igesi kweendawo ezincinane. Sahlulwe Amanqaku okulawula gas (1000-30000 NM ³ / h) kunye iyunithi yolawulo gas (1500 m ³ / h).
• Control kunye nokusasazwa Amaziko - kushishino feed kunye nezibonelelo ezisemaphandleni, imibhobho ring iindawo ezingqonge ezinkulu needolophu 2000-12000 m ³ / h).
• Vuna GRS - ezifakwe kwi emasimini esisi, ngokuthi kungengokwentlambululo yendawo izinto kufunxwa ekrwada ukusuka ukufuma kunye ukungcola.
• izitishi End - zakhiwa kubathengi (amashishini, uluntu) ngqo.

isilawuli esizisebenzelayo

Kwiminyaka yakutshanje, ngokubanzi nokuhambisa station lonikezelo igesi. AGDS amandla ku 200,000 m ³ / h asebenza ebumnandini. Kulo mzekelo, isikhululo kufuneka uluhlu lwezixhobo kunye lezixhobo, ukuvumela ukwenza ukusebenza kwawo kwimo oluzenzekelayo.

Ukugcinwa GDS eyenziwa kude. Umqhubi we izikhululo distribution igesi, ngokuqhelekileyo ibekwe kwindawo bombutho nkonzo, esweni kunokwenziwa nokuba ekhaya. Kwimeko apho isandi likaxakeka kunye nemiqondiso kukukhanya idluliselwe kwindawo namakhaya abasebenzisi, ezithi zibekwe kumgama ongekho ngaphezulu kwe-0.5 km ukusuka kwisikhululo kolawulo. GDS ukusebenza inkonzo phezu 200,000 m ³ / h senziwe aqalise yenqanawa.

izixhobo

station lokuhambisa igesi ibandakanya isethi ecacileyo izixhobo zobugcisa:

• ukhupha wawelela device;
• amacebo;
• heater;
• umgca ukunciphisa nokulawula uxinzelelo igesi;
• Ekala isixhobo for sokuqukuqela serhasi engenayo;
• ukuxhumana kwefowuni kwimveliso.

Njengoko nabalawuli uxinzelelo bewasebenzisa nabaqondisi kwisikhululo RD ngqo nengxelo- zodidi lwentshukumo RDU.

umjikelezo kwezobuchwepheshe

Ifumene engenayo station lonikezelo igesi. Scheme intshukumo yawo ahambelana nokuhanjiswa processing ngolu hlobo lulandelayo:

1. Ukususela igesi yombhobho engundoqo Ozahlulayo isixhobo kuthatha indawo ekuqaleni kwaye engena lokucoca ulwelo.
2. Emva koko ke ungabutofela ekunciphiseni kwinqanaba lokuqala, ukuba imigca ezimbini okanye ezintathu, enye yazo a yogcino. Xa kukho sika-imigca emibini, msonto yokulinda ibalwa kwenye umthamo ezilikhulu ekhulwini, ngoxa kwimeko imigca emithathu - 50%. Eceleni line xa uthe yesekethe zingasetyenziswa yokucima inqanaba lokuqala.
3. Xa uxinzelelo owongozelelweyo yi-4 MPA GDS, uxinzelelo igesi kwinqanaba lokuqala kunciphisa ukuya 1-1.2 MPA, kunye Inqanaba lesibini ukuya 0.2-0.3 MPA. Emva uxinzelelo igesi Isigaba sesibini siya kuba ixabiso 0.6-0.7 MPA.

Ukufakelwa izihluzi kunye nokulawula uxinzelelo

Ukhetho isithuba ufakelo lokucoca kuxhomekeke uxinzelelo igalelo kunye nokwakheka negesi. Ukuba isikhululo unikezelo ifumana irhasi umanzi, isihluzo esinye kufuneka sifakwe phambi kokuba ekunciphiseni isigaba 1. Lokucoca ulwelo kulo mzekelo abe sisibatha condensate, kunye ukungcola mechanical. Emva koko, umxube eluthulini kunye condensate ongena kwiitanki neentlenge. Le mveliso badibanisa ithunyelwa netanki apho uvelisa zokumpompa ngamaxesha athile ngaphandle xa zidlula.

Ukuba igalelo GDS uxinzelelo ngaphantsi kwe-2 MPA ukusebenza, lo amacebo ibekwe emva kokuba ekunciphiseni isigaba 1. Kwimeko enjalo isicwangciso scheme amacebo bathela udluliselwe (Wahlanganisa esa line) kweqonga yokuqala. Le okucoca kule meko umiselwe ukuya uxinzelelo 2.5 MPA. Ngokwandisa uxinzelelo ugwebu zerhasi phezu 2.5 MPA, isixhobo ukhupha kumgca bypass i ivaliwe kunye negesi kufakwa kumnombo ngokucuthwa sigaba 1. Emva gas yayo sicatshulwa anikwe Inqanaba lesibini, yaye emva kwemizuzu-2 - nomnye umbhobho.

Ukuba isikhululo unikezelo ifuna izixhobo replacement ekunciphiseni umgca ephambili, ngokunjalo nokudala imveliso olungxamisekileyo kulo line kunye nokuvula umgca bypass le zinikwe isixhobo nokukhubeka kunye isivalo nokunciphisa. Ukulungisa le isantya sokuqukuqela serhasi kunye noxinzelelo oluqhutywa kulo mzekelo ngesandla.

Icebo isikhululo lonikezelo igesi ezenzekelayo

izitishi automated distribution segesi iinketho eziliqela ngenxa Ubeko izixhobo. Nakuba kunjalo, kufuneka zonke zithathelwe ingqalelo njengoko ingozi ukuphilisa ukubunjwa ebandayo imikhosi yangaphandle ukwehla yangaphandle. Ngoko ke, ebusika abasebenzi isikhululo bakhonza kufuneka anikele ingqalelo ekhethekileyo zinto zikhankanywe ngasentla. Ukuze kuthintelwe ekwakhiweni ukuphilisa kwi GDS kusetyenziswa iiyunithi ukufudumeza igesi.

ibandla ukufudumeza luquka isifudumezi kunye kwibhoyila. Amanzi nakwesiphi kwibhoyila kwisikhongozeli okhethekileyo, ukufudumeza efanelekileyo amanzi kwibhoyila lwenziwa yi ukutshiswa irhasi ebebunikwe loo GDS kunye nenkqubo nokuncitshiswa zesini. Gas sokukhuphela izixhobo kwibhoyila isebenza ngamandla igesi eliphantsi. Ukuthintela igesi feed ukuya ukutshiswa ezikweni kwibhoyila noxinzelelo elingaphaya kwemida lusekiwe, kukho isixhobo ukhuseleko. Ngenxa yoko, uxinzelelo igesi nghena GDS ngqo kuqala coca ulwelo, emva koko preheater. Le preheater na osuke igesi eyayibangelwa lulo ukuphilisa isusiwe. Ozayo heater, irhasi dehumidified ungena cut-line kwaye emva koko ukuya umbhobho.

amanyathelo okhuseleko

Ukuthintela udubulo kwaye imililo kwi GDS ukuseka kwiiyunithi zemfundo eneemfuno ezizodwa ukuze ndinabele igesi ivumba. Ezi zicwangciso zibekiwe xa kungekho izakhiwo intloko igesi odorizing okanye isidanga yalo nemida. Ukufakelwa odorization gas yahlulwe ukumpompoza uvuza kunye umsonto. ZifunwaEzokugqibela zidweliselwe ngokuba nangoku ngumphunga.

Ukufunyanwa okuzenzekelayo kwisikhululo lonikezelo igesi

Umgaqo ukusebenza isikhululo lonikezelo igesi automated inkonzo home-based ngolu hlobo lulandelayo. Kwimeko yoxinzelelo output gas phezu ixabiso kuvumelekile, woluvo lumiselwe ixabiso elithile, eyalela ivelufa shintsho nesikhululo abasebenzi kodityaniso ngaxeshanye nge isandi kunye ukukhanya kweesiginali, ibekwe kwi iingweletshetshe.

Kwimeko apho kukho ukwanda yengcinezelo igesi ngamashishini le SDG-5% ngaphezu yexabiso xi ngegama, umenzi woluvo oluhambelanayo sakhubeka. Ngenxa yoko, ukulawula umba kwesinye imigca zokusebenza ukwehla iqalisa ukuvala, ngokwenjenjalo kuncitshiswe uxinzelelo yokuphuma igesi. Ukuba xi swi bunciphe, kuya kusebenza omnye umenzi woluvo ukuba uya kuxhokonxa langaphandle ngakumbi impompo olawula de qhawula ngokupheleleyo yonke ekunciphiseni line. Kwimeko yokunciphisa uxinzelelo imveliso 0,95R, umgca yokulinda ivulwa.

isimo technical

Ngaphandle elula ifowuni, isikhululo distribution igesi abadinga yokubuyekeza. Ukwakhiwa lwezitishi distribution igesi kwiimeko ezininzi kwenziwa 70s, xa lwemibhobho babekwa amawaka eekhilomitha ukusuka namasimi eSiberia kubasebenzisi baseYurophu, nako kuthwalelwa phandle umntu ubunzima gasification zokuhlala kunye namashishini eSoviet Union. Phantse 34% of GDS ibhiyozele iminyaka eli-30, 37% - ngaphezu kweminyaka eli-10, ngaphantsi kwesinye kwisithathu izitishi baxhotyiswa izibonelelo zale mihla ngaphantsi kweminyaka eli-10. Okwangoku, siye ingqalelo inkqubo ebanzi technical kwakhona izixhobo kunye nokwakhiwa ngokutsha kwezikhululo distribution gas.
