Yakagadzirwa nezvinodiwa nenzira dzekubvisa acid gasi uye maitiro ekuchenesa ethane mupfungwa, maLonnmeter transmitters anodzivirira pressure pulsation uye particulate fouling. Izvi zvinovandudza kushanda kwenguva refu mugasi rekugadzirisa zvinosanganisira maabsorption towers uye regeneration towers, uko kuyera kusimba kwepressure kwakakosha kuti pave nereflux ratio chaiyo uye reboiler heat duty optimization.
Kusiyana nematransmitter akajairwa, mayuniti eLonnmeter ane maelectronic akavharirwa anoderedza njodzi yekuora uye anobvumira kushandiswa munzizi dzekugadzira gasi dzakanyorova kana dzakasvibiswa. Anoenderana nemaitiro mazhinji ekugadzirisa gasi rehydrocarbon, zvichibvisa kudzokororwa kwekuchinjana kana kutadza kwemasensa nekuda kwekusvibiswa. Izvi zvinoita kuti pave nekutarisa kwakavimbika kwekuchengetedzwa nguva dzose uye kutevedzera mitemo mumagetsi ekubvisa gasi reacid negasi rechisikigo.
Kugadzirisa nguva dzose hakuwanzoitiki nekuda kwekuongorora kwakavakirwa mukati mehurongwa. Kuchinja uku kubva pakugadzirisa zvinokanganisa mashandiro emagetsi kuenda pakugadzirisa zvinofanotaura kunobatsira kutarisirwa kwenzvimbo dzakachengeteka uye kuderedza mari yese yekuva muridzi. Nekuda kweizvozvo, vatariri vemafekitori nemainjiniya ezvishandiso vanogona kuchengetedza huwandu hwakawanda hwemagetsi uye kushanda mukati memiganhu yeutsi, zvakakosha pakushandiswa kwegasi mumafuta negasi nezvimwe zvinoshandiswa.
Maitiro Ekubatanidza: Kumbira Mutengo kana Kubvunzana Nehunyanzvi
Mamaneja emafekitori, mainjiniya emidziyo, uye vatungamiriri vezviteshi zvegasi vanogona kutanga maitiro ekubatana neLonnmeter mumatanho matatu ari nyore. Chekutanga, kubata vatengesi vehunyanzvi zvakananga kunogonesa kuongororwa kwakadzama kwemamiriro ezvinhu chaiwo efekitori—senge matambudziko akasiyana ekudzivirira kwemvura inonaya kana kudiwa kwekugadzirisa kushanduka kwemasaini. Izvi zvinogona kuitwa kuburikidza neemail, runhare, kana fomu rekubvunza online.
Chechipiri, panguva yekukurukurirana kwehunyanzvi, timu yeLonnmeter ichaunganidza maparamita anoenderana nekushandiswa, kusanganisira kuumbwa kwegasi remagetsi, kumanikidzwa kwetower yekunyudzwa kwechinangwa, uye zvikonzero zvinotarisirwa zvekuputika kwesimba uye zvipingamupinyi zvekuderedza. Maitiro aya akagadzirwa anovimbisa kuti transmitter yega yega inoenderana nemamiriro ekushanda.
Chechitatu, mushure mekuongororwa kwechikumbiro, vatengi vanowana mutengo wakadzama uye wakagadzirirwa iwe. Kana zvichidikanwa kusimbiswa kwakawedzerwa, zvikamu zvekuratidzira zvinogona kurongwa panzvimbo yacho, zvichitsigira kuongororwa kwemaoko mumamiriro ezvinhu chaiwo. Maitiro aya anotendera vane chekuita nematanho kuti vave nechokwadi chekuti maLonnmeter inline pressure transmitters anozadzisa zvese zvinodiwa pakushanda uye kutevedzera zvinodiwa pakushanda kwakaoma kwegasi risati raitwa zvizere.
Mibvunzo Inowanzo bvunzwa (Mibvunzo Inowanzo bvunzwa)
Ma "inline pressure transmitters" anobatsira sei kudzivirira kuvharika kwemvura inodziya mumapaipi?
Ma "inline pressure transmitters" anoita basa rakakosha munzira dzinoenderana ne "gas recovery" uye kugadzirisa indasitiri yekugadzira gasi rehydrocarbon. Midziyo iyi inopa data rekumanikidzwa rinoenderera mberi, zvichibvumira vashandisi kuona kudonha kamwe kamwe kana ma "pressure profiles" asina kurongeka - chiratidzo chinowanzoonekwa chekuunganidzwa kwe "condensate" mumapaipi. Kuziva maitiro aya munguva chaiyo kunoita kuti pave nekupindira nekukurumidza, senge kugadzirisa ma "operating parameters" kana kutanga "pigging routines", izvo zvinoderedza njodzi yekuvharika kwe "condensate". Iyi nzira yekudzivirira inobatsira kudzivirira kuvharika kusina kurongwa uye inochengetedza mafambiro akasimba, ichivimbisa kuvimbika kwekushandiswa kwegasi munzvimbo dzemafuta negasi.
Ndeipi basa rema inline sensors mukugadzirisa mashandiro eshongwe yekunyudza?
Masensa ari mumutsara—kusanganisira ayo ekuyera kumanikidzwa, mwero, kuwanda, uye tembiricha—akakosha pakugadzira uye kushanda zvakanaka kweshongwe yekunyudza, kunyanya mumabasa ekubvisa acid gas unit. Masensa aya anopa data renguva chaiyo rinotsigira kushanda kwakasimba kweshongwe dzekunyudza mukugadzirisa gasi. Semuenzaniso, ma "pressure transmitters" anobatsira kuchengetedza kumanikidzwa kwakakosha panzira dzekubvisa acid gas mukugadzirisa gasi rechisikigo. Data rakarurama kubva kuma "inline sensors" rakakosha pakuverenga reflux ratio chaiyo yekugadzirisa gasi, izvo zvinokanganisa kushanda zvakanaka mukuparadzanisa acid gas uye zvinowedzera kushanda kwese kwema "natural gas acid removal systems".
Zvishandiso zvekuyera kumanikidzwa zvinotsigira sei kugadzirisa basa rekupisa reboiler?
Kuyera kumanikidzwa kwakanyatsojeka pachikamu che reboiler kunoita kuti pave nekudzora kumanikidzwa kwakasimba, izvo zvakakosha pakugadzirisa kudziya kwe reboiler mukugadzirisa gasi. Vashandi vanovimba nekuverenga uku kuti vawedzere kupisa, zvichikanganisa zvakananga kushanda zvakanaka kwe reboiler. Kumanikidzwa kwakarongeka zvakanaka kunotsigira kuverenga kwakanaka kwe reboiler, zvichiita kuti kubviswa kwegasi rine acid kurambe kwakanaka pasina kurasikirwa nesimba kusingakoshi. Kutarisa kumanikidzwa nguva dzose kunoderedza njodzi dzine chekuita nekuputika kwesimba mumidziyo yekugadzira gasi, iyo, kana ikasadzorwa, inogona kukanganisa kudziya nekuparadzaniswa.
Sei kudzora kusvibiswa kwezvikamu zvakakosha muzvikamu zvekubvisa acid gas?
Mumayuniti ekubvisa acid gasi, kusvibiswa kwezvikamu kunogona kukonzera kuwedzera kwekudzikira kwedzvinyiriro pamidziyo yakaita sema absorbers nema regenerators. Kudzivirirwa uku kwakawedzera hakungoderedzi kushanda zvakanaka kwemuchina chete asi kunowedzera njodzi yekukundikana kwemidziyo. Kuyerwa kwedzvinyiriro yemukati kunobvumira vashandi kuona nekukurumidza kushanduka-shanduka kwedzvinyiriro, izvo zvinogona kuratidza kusvibiswa kwekutanga. Kuzivikanwa kwekutanga kunobvumira kupindira nenguva - kuchenesa kana kuchinja mamiriro ekushanda - uye kunotsigira nzira dzekudzora kusvibiswa kwezvikamu zvinodzivirira matekinoroji ekugadzirisa gasi rehydrocarbon kubva mukurasikirwa nekushanda nguva dzose.
Ndeupi musiyano uripo pakati peRosemount 3051 ne2088 pressure transmitters dziri kushandiswa?
Muchina we differential pressure transmitter 3051 unofarirwa kushandiswa pakushandisa zvinoda kuyera kwakanyatsojeka, zvakaita sekudzora reflux ratio muma distillation columns kana kutarisa kudonha kwepressure pama reboilers. Kunyatsoita kwayo kunoita kuti ikwane zvakanaka apo nuanced pressure distributions dzinofambisa nzira dzinoshanda dzekubvisa acid gas. Modhi ye2088, zvakasiyana, yakagadzirirwa gauge yakatwasuka kana absolute pressure monitoring, yakakodzera mamiriro ebasa akaoma apo kuvimbika kwakakosha. Kunyange zvazvo mhando dzese dziri mbiri dzichigona kutsigirwa netsanangudzo dzekuisa uye calibration, sarudzo inoenderana nezvinodiwa pakuita - differential control uchienzaniswa ne rakasimba, single-point pressure readings.
