Iyunithi ye-natural gas wellhead dehydration
Ukucushwa kweyunithi
(1) Iyunithi yokukhipha amanzi emzimbeni ifakwe eqhweni, futhi okokusebenza kukagesi namathuluzi aku-skid akukwazi ukuqhuma.
(2) Iyunithi yokukhipha amanzi emzimbeni ifakwe endlini.Umphakeli kufanele aklame isistimu efanele ngokuvumelana nezimo zezinga lokushisa eliphansi ebusika ukuze aqinisekise ukusebenza okuvamile kweyunithi yokuphelelwa amanzi emzimbeni ebusika.
(3) Wonke amapayipi okusebenza axhunywe ohlangothini lwe-skid, futhi wonke amapayipi okukhipha ama-valve okuphepha namapayipi ahlabayo axhunywe ohlangothini lokushibilika ngezindlela eziningi.
(4) Izokwazi ukusebenza kahle ngaphansi kwemibandela ebhalwe kudatha yemishini.
(5) Wonke ama-flange azoxhunywa umnikazi azofaniswa ne-butt welding flange ne-gasket, ibhawodi namantongomane.Izinga le-flange ngu-Hg / t20592-2009, i-flange ithatha ubuso be-RF, uchungechunge lwe-B, kanti impahla ingu-16Mn;I-spiral wound gasket standard yi-Hg / t20610-2009, izinga lokucindezela liyafana ne-flange, i-gasket ithatha i-gasket yesilonda esivunguzayo esinendandatho yangaphakathi kanye nendandatho ephakathi, indandatho ephakathi yinsimbi ye-carbon, impahla yebhande lensimbi nengaphakathi. indandatho ingu-0Cr18Ni9, ukupakisha kuyibhande le-graphite eliguquguqukayo;i-stud iyinhloso ekhethekile egcwele intambo (35CrMo), ngokusho kwe-Hg / t20613-2009;i-nati iwuhlobo lwe-II hex nut (30CrMo), ngokusho kwe-GB / t6175.
(6) Inqubo yokuvuselela ingumjikelezo ovaliwe wokucindezelwa olinganayo nokushisisa kukagesi kwangaphandle.
(7) Isihlungi sifakwe endaweni yokungena ngokunemba kwesihlungi ≤ 10 μ m, esingavikela ngempumelelo i-adsorbent ukuthi ingacwiliswa futhi ingcoliswe uketshezi futhi yandise impilo yesevisi ye-adsorbent;isihlungi sothuli sifakwe endaweni yokuphuma ngokunemba kwesihlungi se-3 μ m, esingavikela ukusebenza okuvamile kwama-compressors alandelayo.
(8) Uhlelo lokuvuselela lwamukela i-compressor yokujikeleza ukushayela ukuvuselelwa kokujikeleza, futhi uhlelo lokuvuselela lufakwe isihlukanisi samanzi egesi ukwenza ukuvuselelwa kwegesi yokuvuselela igesi.
(9) Isihlukanisi samanzi egesi sinokuhlukana kabili kwamandla adonsela phansi kanye nokuhlunga, okunomphumela omuhle wokuhlukanisa.Ithangi lokugcina uketshezi libekwe ngemuva kwesihlukanisi samanzi egesi enomthamo wokugcina uketshezi ongu-0.05m3 ukuhlangabezana nokukhishwa okuphelele kokuvuselelwa.
(10) Uhlelo lokulawula: Ukulawulwa kohlelo lwe-PLC kuhlanganisa ukulawula izinga lokushisa okungaguquki kanye nesikrini sokuthinta.Ngemva kokuba okokufaka kwepharamitha yokulawula kucutshungulwe, kuzovezwa esikrinini se-LCD, futhi uhlelo olusethiwe luzolawula ngokuzenzakalelayo ukusebenza okuvamile kwefeni elijikelezayo, i-heater, i-cooler ne-anti freezing kanye nedivayisi yokulondoloza ukushisa.Ifakwe insimbi yendawo kanye nensimbi yokulawula yasendlini, kanye nethuluzi lokulawula kude.Ukuqala nokumiswa kwe-cooler yokuvuselela kabusha, i-booster ejikelezayo kanye ne-heater kagesi kungabona isilawuli sokukhiya ngogesi kanye nokulawula okuzimele okwenziwa ngesandla, nokulawula okwenziwa ngesandla kuyakhethwa.Ukuqapha inzwa yokushisa yamaphuzu amaningi, ukubonisa okunembile nokulawula indawo yokufudumeza, indawo yokuvuselela igesi kanye nezinga lokushisa elipholile, lawula okokufaka kwemingcele ku-PLC processor emaphakathi ukuze icutshungulwe, nokulawula isenzo sohlelo lokuvuselela ngokohlelo olusethiwe, futhi ifakwe ukuxhumana okukude. isikhombimsebenzisi, isikhombimsebenzisi se-RS485, iphrothokholi yokuxhumana yi-MODBUS-RTU.Iswishi yokuvikela ukushisa ngokweqile, gwema ukushiswa kwe-heater, vikela impilo yezinto zokushisisa ngogesi.
(11) Ikhabhinethi yokulawula ye-PLC ihlelwe egumbini lokusabalalisa amandla esiteshini, futhi iKhabhinethi yokulawula ye-PLC kufanele ifakwe izifudumezi zasemkhathini ukuze kuqinisekiswe ukusebenza okuvamile kwendawo yokushisa ephansi ebusika.
(12) Umsebenzi wokuvikela ukuphepha: umgqomo we-heater kanye ne-outlet kunikezwa umsebenzi wokuvikela izinga lokushisa;i-motor inikezwa ukuvikelwa kokushisa nokuvikelwa kwesifunda esifushane, futhi uhlelo lukagesi lunikezwa isifunda esifushane nokuvikelwa kokuvuza.
(13) Injini yamukela injini engashi, izinga lokuvikela ukuqhuma alikho ngaphansi kwe-Exd Ⅱ BT4, izinga lokuvikela lamathuluzi kagesi alikho ngaphansi kwe-IP54, futhi izinga lokuvikela lensimbi yasensimini alikho ngaphansi kwe-IP55.
(14) Isipholile somoya: isishintshi sokushisa se-tube fin
Ukucushwa kwesakhiwo
(1) Ngemva kokuba umbhoshongo we-adsorption usongwe ngezinto ezishisayo, ugoqwa ngepuleti lokuhlobisa le-aluminium, elikwazi ukumelana nokugqwala okuhle nokubukeka okuhle.
(2) Ishubhu yokufudumeza kagesi iwuhlobo olubalulekile, elenziwe ngensimbi engagqwali 1Cr18Ni9Ti.Amandla okushisa angaphezulu kweshubhu yokufudumeza kagesi afinyelela ku-2.0w/cm 2.
(3) Imbobo yesampula yokuhlaziya iphuzu lamazolo isethwe lapho kuphuma khona iyunithi yokuphelelwa amanzi emzimbeni.Ifakwe imitha yephoyinti lamazolo eku-inthanethi.
(4) Umbhoshongo we-adsorption ufakwe igeji yokubonisa ingcindezi yendawo kanye ne-thermometer ukuze ubonise ingcindezi yokusebenza kanye nezinga lokushisa lombhoshongo we-adsorption;isistimu yokuvuselela ifakwe i-thermometer, igeji yokucindezela kanye ne-thermocouple ukuze idlulisele kude izinga lokushisa lokuphuma kwe-heater yokuvuselela, igesi epholile kanye nokuvuselelwa kabusha kombhoshongo we-adsorption ekamelweni lokulawula;ikhabhinethi yokulawula ifakwe amathuluzi okulawula we-PLC.
(5) Zonke izinto ezisebenza ngogesi ocingweni ziwumklamo ongaqhumi.Izinga elikusayithi lokuvikela ukuqhuma alikho ngaphansi kwe-Exd Ⅱ BT4, ileveli yokuvikela yi-IP54, futhi ileveli yokuvikela insimbi ekusayithi ayikho ngaphansi kwe-IP65.
(6) Wonke ama-nozzle angaphandle axhunywe ku-skid.
(7) Umbhoshongo we-adsorption ufakwe imbobo ekhethekile yokulayisha nokulayisha yesisefo samangqamuzana, esilungele futhi esisheshayo ukushintshwa kwesisefo samangqamuzana.
(8) Kukhona i-valve yokuphepha ohlelweni lokuvuselela.
(9) Izinto ezisetshenziswayo ezinjengombhoshongo we-adsorption, isifudumezi segesi esikhiqiza kabusha, ukushaywa phansi kwesihlungi se-inlet esihlukanisayo, isihlukanisi samanzi segesi esikhiqiza kabusha, ukuphehlwa kwethangi eliqoqa uketshezi kanye namapayipi awo axhumayo azovalwa.Uma izinga lokushisa le-ambient lingaphansi kuka-5 ℃, isistimu ye-blowdown ingaqalwa ukuze kugcinwe ukushisa nokulandelwa.
Ukwelashwa kwe-anti corrosion kanye nokugcina ukushisa
(1) Iphathi B izoba nesibopho sokufafaza i-primer kanye nopende wokuqeda kuzo zonke izingxenye ngaphandle kwemikhiqizo yensimbi engagqwali nezingxenye ezijwayelekile.
(2) IQembu B liyoba nomthwalo wemfanelo wokuthenga nokusonga izinto zokufakelwa kanye namapuleti e-aluminium ombhoshongo we-adsorption, heater kagesi kanye nepayipi
Ikhasimende lidinga ukunikeza ulwazi
Ingcindezi yokungena komoya, ukugeleza kwe-air inlet, indawo yamazolo yamanzi angenisa umoya nendawo yokukhipha igesi indawo yamazolo (uma kwenzeka igesi yemvelo engajwayelekile, ngaphezu kwalokho, izinga lokushisa lokungenisa komoya kanye nokwakheka kwegesi kuzohlinzekwa. Igesi yemvelo engajwayelekile ngokuvamile ihlanganisa igesi yomthombo, igesi yamalahle. , igesi ye-shale, i-biogas, igesi, njll.).
