Ukulinganiswa Kwegesi

Ukulinganiswa kwegesi ezimbonini zenqubo yamakhemikhali kubalulekile ekuphepha, ezindlekweni, ukuthobela imvelo, ukulawulwa kwenqubo, ukumsulwa komkhiqizo, Ukusebenza kahle kokukhiqiza, ukuthobela imvelo. Okungalungile nokungahambisani kungaholela ezingozini ezinkulu ezizodala ukuvuza kwegesi okuyingozi, ukunakekelwa kwezimo eziphuthumayo, inhlawulo kahulumeni, ngisho nokukhiqiza kwavalwa. Izilinganiso ezingalungile zinganezela ngokushesha emalini amakhulu okukhokha ulwazi.

Isilinganiso semidiya yegesi siyinkimbinkimbi kakhulu kunezilinganiso zemidiya engamanzi. Nazi izilinganiso ezine ezijwayelekile zegesi okumelwe ukwethule.

1.flow mita

Amamitha wokugeleza anquma ukugeleza kobuningi okudlula ngemitha.

Ukusatshalaliswa kwegesi. Izinqubo eziningi zamakhemikhali zidinga imithamo emikhulu ehlukahlukene yamigesi athile, njenge-nitrogen, i-argon ne-oxygen yama-ions e-inert noma ukuhlanza noma ingubo. I-Hydrogen ingadingeka njenge-catalyst namanye amagesi athile asetshenziswa. Ukulinganiswa okunembile kwalawa magasi kuyadingeka ekulawuleni inqubo, ukulawulwa kwe-ges-inventory kanye ne-coss

Ama-flowmeters e-Coriolis ahlinzeka ngesilinganiso esiqondile sokugeleza ngobuningi ngokususelwa emandleni okuphambuka uketshezi okuhamba ngebhabhu elidlidlizayo e. Lawa mamitha anembile kakhulu ngamakhono okushintsha kakhulu futhi azimele ezindaweni eziketshezi. Futhi zibiza kakhulu ukuthenga nokufaka futhi azilungele usayizi omkhulu wamapayipi.

Ingubo yethangi. Ukuguquka kwe-nitrogen kusetshenziswa ezimbonini zokucwenga kwamakhemikhali kanye nophethiloli ukunciphisa izingozi ezihambisana noketshezi oluvuthayo, okusiza ukuxhasa ukuphepha kwezitshalo futhi kungakhuphula umkhiqizo. Ukubhukuda noma i-padding inqubo yokufaka igesi ye-inert nitrogen endaweni yomhwamuko wethangi noma umkhumbi, okunciphisa ukuthi kungenzeka ukuqhuma noma umlilo ngokunciphisa okuqukethwe komoya-mpilo noma ukuhlangana komhwamuko ovuthayo noma wokuqhuma.

Izinhlelo zokukhanya. Ekukhiqizweni kwe-petrochemical, ukucwengisisa nokugcina, amasistimu egesi aphansi asetshenziselwa ukushisa nokulahla imfucumfucu, ngokweqile noma ngaphandle kwegesi futhi njengohlelo lokuphepha. Ukulinganisa okunembile, okuphendulayo nokuthembeka kwegesi ye-flare kubalulekile ukuze kuqinisekiswe ukusebenza okufanele kohlelo lwegesi elifulayo, okuvikela abantu nemishini kumagesi avuthayo ayingozi ukuze kugcinwe indawo ephephile yokusebenza nokugwema ukungcoliswa kwemvelo.

Ukuqapha igesi yesitaki. Ukulinganisa ukukhishwa kwamagesi emfucumfucu yezitshalo ngezitaki ezinkulu ezinezinhlelo ze-screubber kudinga izinzwa eziningi zokugeleza, ezibekwe ezindaweni zamasu (umfanekiso 4). Lezi zinhlelo ze-stack-gas zibalulekile ekuqinisekiseni ukuthobela kwemvelo. Izinhlelo zokuqapha ukukhishwa eziqhubekayo kufanele zihlangabezane namazinga amaningi endawo

Amamitha wokugeleza okushisayo alinganisa ukugeleza okukhulu ngokususelwa ekudlulisweni kokushisa kusuka entweni eshisayo. Isilinganiso sisekuhambo oluningi, futhi ingcindezi eyengeziwe nokulungiswa kokushisa akudingeki. Futhi zinikeza ukunemba okuhle nokuphindaphindeka futhi kulula ukukufaka.

2. Ijubane

Ngohlobo lwemitha ye-velocity, isilinganiso sesiphakathi esidlula ngemitha sinquma isilinganiso.

Imitha ye-Ultrasonic

Amamitha wokugeleza e-Ultrasonic alinganisa umehluko wesikhathi sokuhamba esihamba esivela ku-transducer esiphansi uye enzwa ephezulu, kuqhathaniswa ne-transducer ephezulu emuva ku-transducer engezansi. Lesi sitayela semitha sinembile kakhulu kepha sibiza kakhulu, futhi ukulinganisa kwengcindezi nokushisa kuyadingeka.

Ikwazi ukulinganisa ngesivinini. Izilinganiso zokugeleza ezinembile zokuhamba phezulu nomfula zidinga izimo zamapayipi amade futhi eqondile. Lawa mapayipi oqondile kungenzeka angenakutholakala ezindaweni zokukhiqiza ezigcwele nasezitshalweni.

3. Amamitha wokucindezela ahluke

Ingcindezi ehlukile. Amamitha wokugeleza kwengcindezi ehlukile abala ukugeleza ngokukala ukwehla kwengcindezi ngaphezulu kwesithiyo esifakwe endleleni yokugeleza. Amamitha wengcindezi ehlukile (DP) nama-transmitter afika ngemiklamo eminingana, kufaka phakathi amapuleti e-orifice, amashubhu e-pitot neVenturis. Imiklamo ejwayelekile yemitha ye-DP idinga uketshezi ukudlula kumaphuzu amabili ethenjwa noma adlule, ukudala izinga lokucindezela okuhlukile elilingana nezinga lokugeleza kusetshenziswa isibalo seBernoulli ngokuguqulwa okuthile. Uma igesi ingcolile, kungaba nezinkinga zokuvala ezidinga ukunakekelwa njalo ukuze kugcinwe ukunemba.

Uhlobo lwamashubhu e-pitot lusetshenziswa ekulinganisweni kokugeleza kwengcindezi ephezulu futhi akulungele ukusebenza kwengcindezi ephandle

Ipuleti le-orifice yimitha yengcindezi ehlukile esetshenziselwa ukulinganisa igesi yemvelo. Ilinganisa ukugeleza kwevolutric, hhayi ukugeleza kobuningi. Ukulinganiselwa kwale mita kufaka phakathi ukuzwela kokugeleza okuphansi, ukushintsha okulinganiselwe, nokwehla kwengcindezi, okuthinta izindleko zokusebenza. Ngokwengeziwe, njengoba kuyimitha yokugeleza ye-volumtric, kuyadingaUkulungiswa kokushisa nengcindezi ukufeza ukugeleza kobuningi.

4. Ukufuduka Okuhle Kwegesi Ukukhuliswa Kwemitha Yokukhulisa

Amamitha afanele wokufudusa adinga uketshezi ukususa izingxenye ngomshini nokukala ukugeleza kwe-volumtric kuzinga lokushisa lokusebenza kanye nengcindezi. Ngenkathi benokunemba okwanele, kunenxephezelo yengcindezi nokushisa kuyadingeka ukufeza ukugeleza kwabantu abaningi, futhi njengoba zinezingxenye ezihambayo, umsebenzisi kufanele abheke ukuhlanzeka kwegesi. Imitha ye-PD ingabizwa ngokuthi yimitha yokugeleza ye-PD noma imitha yokugeleza yevolumu.

Izinto ngaphambi kokukhetha inqubo yokulinganisa nezidluliseli

Ukucabangela Ukulinganisa Ukugeleza kwegesi

Ukukhetha ubuchwepheshe obunembile, obunokwethembeka bokugeleza.

Ukuzwela ezimweni zokugeleza okuphansi kuyadingeka ukukhomba nokukala ama-valve okuvuza kanye nokusebenza okujwayelekile kokugeleza okuphansi imisebenzi yansuku zonke.

Ukulinganiswa kwemitha. Kubalulekile ukuthi ama-flowmeter alinganiswe ngokukhethekile kumagesi okwakhiwa kwe-hydrocarbon nokufanisa izimo zenqubo yangempela.

Ipayipi elikhulu. Kunobuchwepheshe obumbalwa obusebenzayo futhi obufanelekile bokuzwa kokugeleza kwemigqa emikhulu. Kungcono ukuba nesibukiso se-LCD kumdlulisi wengcindezi namamita

Ukufinyelela okulinganiselwe. Ukufinyelela nokufinyelela kabusha kumapayipi wokufakwa, ukugcinwa, noma ukusebenzela kaningi kunzima. Isibonelo, Ama-spool-phice flowmeter angadinga ukuvalwa kwenqubo isikhathi eside kanye nezindleko eziningi zabasebenzi ukufaka nokugcina ngokuqhubekayo uhlelo, ngokungafani namamitha wesitayela sokufaka angafakwa kalula noma ahoxiswe ngaphandle kwenqubo nge-valve yebhola.

Ukucatshangelwa kokufaka

Kunezindlela ezimbili zokufaka i-flowmeter: ngaphakathi noma ukufakwa. Ama-flowmeters e-intline kufanele afakwe ngokuvundlile ngaphakathi kwesigaba sepayipi. Ama-flowmeters okufaka afakwa phezulu ngephoyinti le-tap. Obunye ubuchwepheshe be-flowmeter buthembele ezinzwa eziqondile zokugeleza. Amanye ama-flowmeters enza ukugeleza kobuningi futhi adinga ukuthi kufakwe ingcindezi noma izinzwa zokushisa eduze, kanye nama-transmitter, noma ama-transmitter angaguquguqukayo, angangeza ezindlekweni zabo nasekufakeni kwabo.

Ukucabangela Ukunakekela

Okunye ukulinganisa kwegesi kudinga ukunakekelwa njalo ukuqinisekisa ukuhlanzeka nokuqonda kwengxenye yokuzwa, i-Airtightness, ukufakwa okulula, nokuhlukaniswa nakho kudingeka kucatshangelwe.LEFOOAma-transducers wengcindezi kanye ne-Isidlulisi sokucindezela okuhlukileOkukwazi ukulinganisa igesi kuzilinganiso lwegesi yamakhemikhali kanye nokucindezela kwegesi yemvelo futhi kulula ukuyigcina
