Zvishandiso zvemagetsi zvakaita seLonnmeter models zvinopa kurongeka kwe±0.1% FS munzvimbo dzinoshanda dze100–500 bar dzinowanikwa mumasystem aya. Kutarisa kumanikidzwa panguva yekufambisa ethylene liquid kunodzivirira kubva pakudonha kwemvura uye kumanikidzwa zvakanyanya—zvikonzero zvikuru zvinokonzera njodzi muchikamu ichi. Kuyera kwakasimba mukati memutsara kunotsigira kushanda kwakachengeteka, kunoramba kuripo uye kunowedzera goho munzvimbo dzisina kugadzikana.
Nhanganyaya
Kuyerwa kwekumanikidzwa kwemukati kunopa mhinduro inokurumidza uye chaiyo inokosha pakudzora copolymerization yerubha re ethylene-propylene. Mvura ye ethylene ine pressure yakakura uye propylene inoda miganhu yakasimba yekumanikidzwa panguva yekufambisa uye kuita. Kuchinja-chinja kamwe kamwe mukumanikidzwa kwetangi rekuchengetera mvura ye ethylene liquid—kazhinji kubva mukuvapo kwe cryogenic—kunogona kukonzera kuchengetedzeka kwekubatanidza kana kutadza kukuru kana kusingaonekwe ipapo ipapo. Kuchengetedzeka kwetangi rekuchengetera ethylene kunoenderana nekuverenga nguva dzose kudzivirira kubuda kwemvura uye kumanikidzwa kwakanyanya. Lonnmeter online pressure transmitter yezvinwiwa inoongorora shanduko idzi munguva chaiyo, ichiratidza nemazvo mamiriro ezvinhu. Maindasitiri epressure transmitters anochengetedza kuyerwa kwakasimba pasinei nekudengenyeka, insulation, kana condensation inowanzoitwa muindasitiri yerubha re ethylene-propylene. Kuisa pressure transmitter kwakakodzera kunoderedza kudonha kwemidziyo uye kupindira kwechiratidzo, zvichitsigira kutevedzera mitemo uye kudzivirira tsaona. Kuyerwa kwemukati kunodzivirira vashandi, midziyo, uye kuvimbika kwechigadzirwa panguva yekufambisa uye kuchengetedza mvura ye ethylene liquid, zvichiita kuti kushanda zvakanaka pakushandiswa kwerubha re ethylene-propylene.

Pfupiso yeMaitiro Eindasitiri
Mvura yeEthylene inomanikidzwa pa5–15 MPa uye inopombwa nemapaipi ane propylene muzvigadziriso zve ethylene-propylene.rabhamashandisirwo. Ma "industrial pressure transmitters", akadai se "on-line pressure transmitter" ye "liquids", anosimbisa mwero chaiwo we "feed" kuti achengetedze hunhu hwe "copolymer". Matangi ekuchengetera e-ethylene liquid anoshandisa "double-walled vacuum insulation", achideredza conductivity ye "thermal conductivity" iri pasi pe0.022 W/(m·K), zvichideredza njodzi dzekupisa. Kuisa "inline pressure transmitter" kunofanirwa kuitwa pamatangi ese ekuchengetera e-ethylene kuitira kuti pave nekubuda kwemvura nekukurumidza uye kuonekwa kwe "pressure surge", zvichitsigira kuchengetedzeka kwe "ethylene liquid transport" uye "reactor feed integrity". Kutonhodza uye kupatsanurwa kwe "gas-phase" kunoita kuti propylene concentration target dziri pakati pe35–70%, zvichipa mamiriro akakodzera e "copolymerization reactions". Ma "ethylene-propylene raber compounds" akapedzwa anotamiswa uye anochengetwa pa0.8–1.1 MPa, nekutarisa nguva dzose kudzivirira njodzi dze "vaporization" uye kuchengetedza kuvimbika kwezvinhu zve "ethylene-propylene raber industries".
Matambudziko muKuyera Kumanikidzwa Kwakapinza
Mvura inonzi cryogenic ethylene mumatangi ekuchengetera ane madziro maviri, akavharwa ne vacuum inoisa pachena masisitimu emagetsi anopinza simba remhepo ari paindaneti kuti akurumidze kuchinja simba remhepo. Kuchinja-chinja kunokonzerwa nemhepo kunodarika 25 bar/min muzviitiko zvinokanganisa, zvichida ma transmitter ane nguva yekupindura kwe millisecond. Kuchengetedzeka kwetangi rekuchengetera ethylene kunoenderana nekuyera kwemukati kwemaawa makumi maviri nemana, sezvo kurasikirwa ne insulation kana kusangana nekupisa kunogona kukonzera kudzvanywa kwakanyanya mukati memaminitsi. Magasi akanyungudutswa uye reactive propylene mu ethylene-propylene raber applications zvinokonzera kusagadzikana kwenguva pfupi, kusanganisira sensor spikes kusvika ±1% yakazara, izvo zvinoomesa kudzora mashandiro. Ma industrial pressure transmitters anotarisana nekukanganiswa kubva ku process insulation, vibration, uye condensation, izvo zvinoderedza kururamisa kwe sensor ne0.5% kana kupfuura uye zvinoderedza hupenyu. Kuiswa kwepressure transmitter mumaindasitiri e ethylene-propylene raber kunoda waya dzakasimba uye dzimba dzisingapindi mamiriro ekunze, sezvo tembiricha yemhepo inowanzo pfuura 45°C uye mazinga ekuvhunduka achisvika 5 g. Maitiro ekuchengetedza ekufambisa ethylene liquid anoda mhinduro pakarepo kubva kumatransmitter epamhepo kuenda kuma interlocks ekuchengetedza, sezvo kudonha kwemvura uye kumanikidzwa kwakanyanya mumitsetse yekufambisa kunogona kugadzira musanganiswa unoputika mukati memasekonzi.
Mabhenefiti ekubatanidza maInline Pressure Transmitters
Kuverengwa kwesimba panguva chaiyo kubva ku-on-line pressure transmitter yezvinwiwa kunogonesa kudzora kwe-closed-loop panguva ye ethylene-propylene rubber copolymerization. Kuyerwa kwe-inline kunoderedza njodzi yekuchinja-chinja muma reactor ane ethylene liquid ne propylene yakamanikidzwa, zvichideredza kuvharwa kusina kurongwa kusvika ku32% (ICIS, 2024).
Kukurumidza kuona kudonha kwemvura uye kudzvanywa kwakanyanya mumatangi ekuchengetera ethylene liquid uye mapaipi eprocess kunopfupisa nguva yekupindura. Mhinduro ye sensor yakananga inokonzera kuvharika kwekuchengetedza usati wasvika pamiganhu ine njodzi, zvakakosha pakuchengetedza kwetangi rekuchengetera ethylene. Tsvagiridzo inoratidza kuti kupindira nekukurumidza kunodzivirira 60% yezviitiko zvinogona kuburitswa (Process Safety Progress, 2025).
Kugadziriswa kwemaitiro otomatiki kunoitwa uchishandisa maindasitiri ekupinza simba panguva dzakakosha. Izvi zvinoderedza kupindira kwevashandi uye zvinogonesa otomatiki yakazara mumaindasitiri erabha e-ethylene-propylene. Mafekitori anotaura kudzikira kwe17% mukugadziriswa kwemaoko nekuiswa kwemasensa kwakakodzera (Chem. Eng. J., 2024).
Ruzivo rwakarurama rwekumanikidzwa runoderedza kurasikirwa kwemvura ye ethylene panguva yekupatsanurwa, kutamiswa, uye kuchengetwa. Zvirimwa zvinowedzera goho rezvinhu ne4–8%, zvichideredza mari yekushandisa zvakanyanya.
Kuisa pressure transmitter inosangana nezvinodiwa zvakakosha zvekuchengetedza kunochengetedza mitemo yehurumende yekushanda zvine chepfu uye zvinobvira moto. Izvi zvinogadzira rekodhi yakasimba yekuongorora zvese zvinoshandiswa nerabha re ethylene-propylene uye kuchengetedzeka kwekutakura kwemvura ye ethylene.
Kumbira Mutengo
Lonnmeter inopa chinotumira simba remagetsi chepamhepo chakajairwa kushandiswa mumvura, chakagadzirwa kuti chikwanise kushandiswa zvakanyanya nerabha re ethylene-propylene. Nyanzvi dzeLonnmeter dzinopa rutsigiro rwehunyanzvi pakusarudza chinotumira simba remagetsi chepamhepo, chakagadzirirwa mamiriro akaomarara ekushanda uye chinobudisa mvura chakachena kwazvo.
