Gupima umuvuduko w'amazi ni ingenzi mu gukoresha ethylene-propylene rubber hakoreshejwe ethylene liquid ifite umuvuduko mwinshiporopiline. Ubwiyongere bw'umuvuduko butunguranye buturutse ku gushyuha kw'amazi mu kigega cyo kubika amazi cya ethylene bushobora kongera ibyago byo guturika no kuva amazi mu kirere. Amakuru ya NIST agaragaza ko kwiyongera kwa bar 1 hejuru y'umubare w'amazi mu kigega cyo kubika amazi cya m³ 50 bishobora kurekura umwuka wa kilogarama 20+ mu masegonda make, bigatuma igisubizo mu gihe nyacyo kiba ingenzi.
Kugira ngo ibikorwa bibe byiza mu nganda za ethylene-propylene rubber bisaba kohereza umwuka ushyushye w’amazi kuri interineti wihanganira ubwiyongere bw’umwuka ushongeshejwe n’ihindagurika ryihuse risanzwe mu byiciro bya reactor na pipeline. Guhindagurika kw’umuvuduko bitagenzuwe bishobora gutuma ibicuruzwa bidashyirwa mu buryo buteganijwe cyangwa bigahagarara bitateganijwe, bigagabanya umusaruro ku kigero kirenga 5% buri mwaka mu nganda zimwe na zimwe. Gushyiraho neza transmitter ishyushye bituma habahoethyleneumutekano w'ikigega cyo kubikamo ibintu binyuze mu gutanga amakuru yihuse ku buryo bwo guhuza sisitemu z'umutekano.

Utwuma twohereza umuvuduko mu nganda nka modele za Lonnmeter dutanga ubuziranenge bwa ± 0.1% FS mu rugero rw'imikorere ya bar 100–500 rusanzwe muri izi sisitemu. Gukurikirana umuvuduko mu gihe cyo gutwara amazi ya ethylene birinda amazi ava mu kirere no gukandamizwa cyane—impamvu nyamukuru zitera ibyago mu rwego rw'ibi. Gupima neza mu murongo bishyigikira imikorere itekanye kandi ihoraho kandi bitanga umusaruro mwinshi mu bidukikije bihindagurika.
Intangiriro
Gupima igitutu ku murongo bitanga igisubizo cyihuse kandi gisobanutse cy'ingenzi mu kugenzura copolymerization ya ethylene-propylene rubber. Ethylene liquid na propylene bifite igitutu kinini bisaba imipaka ikomeye y'igitutu mu gihe cyo kwimura no gusubiza. Ihindagurika ritunguranye ry'igitutu cy'amazi ya ethylene mu bubiko bw'ikigega—akenshi rituruka ku guhumeka kw'amazi—rishobora gutera ibibazo bikomeye cyangwa gucika intege mu gihe bitagaragaye ako kanya. Umutekano w'ikigega cyo kubika ethylene ushingiye ku bipimo bihoraho kugira ngo hirindwe amazi n'umuvuduko ukabije. Lonnmeter, umuvuduko wo kuri interineti w'ibinyobwa, ikurikirana izi mpinduka mu gihe nyacyo, igaragaza neza imiterere y'imikorere. Utumashini twohereza igitutu mu nganda tugumana igipimo gihamye nubwo hari ukunyeganyega, gushyushya, cyangwa gushonga bikunze kugaragara mu nganda za ethylene-propylene rubber. Gushyiraho neza utumatuma igitutu bigabanya guhindagurika kw'ibikoresho no kubangamira ibimenyetso, bishyigikira kubahiriza amategeko no gukumira impanuka. Gupima ku murongo birinda abakozi, imitungo, n'ubuziranenge bw'ibicuruzwa mu gihe cyo gutwara no kubika amazi ya ethylene, bigatuma habaho imikorere myiza mu bikorwa byose bya ethylene-propylene rubber.

Incamake y'Ibikorwa by'Inganda
Amazi ya ethylene ashyirwa kuri 5–15 MPa hanyuma agashyirwa mu miyoboro irimo propylene mu byuma byabugenewe byo gukora ethylene-propylene.umugoziikoreshwa. Utwuma twohereza umuvuduko mu nganda, nka Lonnmeter's online pressure transmitter for liquids, twemeza neza ingano y'ibiryo kugira ngo tugumane imiterere ya copolymer. Ibigega byo kubika amazi bya ethylene bikoresha utwuma twombi twuzuyemo vacuum, bigabanya ubwiyongere bw'ubushyuhe buri munsi ya 0.022 W/(m·K), bigabanye ibyago byo gushya kw'ubushyuhe. Gushyiraho utwuma two kubika amazi mu murongo ni ngombwa ku bigega byose byo kubika ethylene kugira ngo habeho gusohoka kw'amazi ako kanya no kumenya ubwiyongere bw'umuvuduko, bishyigikire umutekano wo gutwara amazi ya ethylene no gukwirakwiza neza amashanyarazi. Gukonjesha no gutandukanya gazi bitanga intego yo gupima propylene hagati ya 35-70%, bitanga imiterere myiza yo gukora copolymerization. Ibinyabutabire bya ethylene-propylene byarangiye byimurwa kandi bikabikwa kuri 0.8-1.1 MPa, hagakurikiranwa buri gihe kugira ngo hirindwe ibyago byo gushonga no gukomeza kwizera ibikoresho ku nganda za ethylene-propylene.
Imbogamizi mu gupima igitutu kiri ku murongo
Amazi ya ethylene ashyushye mu bigega bibikwamo inkuta ebyiri, ashyirwa mu byuma bifunganye, ashyira sisitemu zo kohereza umuvuduko w'amazi kuri interineti ku mpinduka zihuse z'umuvuduko. Ihindagurika riterwa no gushyushya rirenze 25 bar/min mu bihe byahindutse, bigasaba kohereza mu byuma bifite igihe cyo gusubiza mu masegonda make. Umutekano w'ikigega cyo kubika ethylene uterwa no gupima amasaha 24/7, kuko gutakaza ubushyuhe cyangwa guhura n'isoko ry'ubushyuhe bishobora gutera umuvuduko ukabije mu minota mike. Imyuka yashongeshejwe na propylene ikoreshwa mu byuma bifunganye mu byuma bifunganye bitera kudahagarara neza, harimo no kwiyongera kwa sensor kugeza kuri ± 1% byuzuye, ibyo bikaba bigora kugenzura uburyo ibintu bikorwamo. Ibigega bifunganye mu nganda bihura n'ikibazo cyo gufunga mu byuma, guhindagura no gushonga, ibyo bikagabanya ubushobozi bwo gukora neza kwa sensor ku kigero cya 0.5% cyangwa kirenze kandi bigagabanya igihe cyo kubaho. Gushyiramo transmitter mu nganda zifunganye za ethylene bisaba insinga zikomeye n'amazu adashobora kwihanganira ikirere, kuko ubushyuhe bwo mu kirere bukunze kurenga 45°C kandi urugero rwo guhindagura rugera kuri 5 g. Uburyo bwo gucunga umutekano w’ubwikorezi bw’amazi ya ethylene busaba ko habaho igisubizo cyihuse kiva ku byuma bitanga umuvuduko kuri interineti bijya ku byuma bifunga umutekano, kuko amazi asohoka n’umuvuduko mwinshi mu miyoboro y’amazi bishobora gutuma habaho uruvange rw’ibiturika mu masegonda make.
Ibyiza byo Guhuza Ibikoresho Bitanga Umuvuduko Binyuze Mu Murongo
Gupima igitutu mu buryo bwihuse bivuye kuri transmitter yo kuri interineti ku binyabutabire bifasha kugenzura ako kanya mu gihe cyo gukora copolymerization ya ethylene-propylene rubber. Ibipimo biri ku murongo bigabanya ibyago byo kwangirika kw'ibinyabutabire birimo ethylene liquid na propylene, bigabanya kuzimya ibintu bitateganijwe kugeza kuri 32% (ICIS, 2024).
Gutahura amazi vuba no gupima umuvuduko mwinshi mu bigega bibika amazi ya ethylene n'imiyoboro y'ibikorwa bigabanya igihe cyo gusubiza. Uburyo bwo gusubiza ibintu mu buryo butaziguye butuma habaho uburyo bwo kwirinda mbere y'uko imipaka iteza akaga igera, bikaba ari ingenzi cyane ku mutekano w'ibigega bibika ethylene. Ubushakashatsi bwerekana ko kwihutira gukumira 60% by'impanuka zishobora guterwa n'ibigega (Process Safety Progress, 2025).
Gucunga ibikorwa byikora bikorwa hakoreshejwe imashini zitanga umuvuduko w’amashanyarazi mu nganda mu bihe by’ingenzi. Ibi bigabanya uburyo abakora ibikorwa bikoresha ikoranabuhanga kandi bigatuma habaho imikorere yuzuye mu nganda zikora ibyuma bya ethylene-propylene. Inganda zivuga ko zagabanutseho 17% mu gihe cyo guhindura imikorere hakoreshejwe intoki iyo habayeho gukoresha neza sensor (Chem. Eng. J., 2024).
Amakuru nyayo y’umuvuduko agabanya igihombo cy’amazi ya ethylene mu gihe cyo kuyatandukanya, kuyamura no kuyabika. Ibimera byongera umusaruro w’ibikoresho ku kigero cya 4–8%, bigabanya cyane ikiguzi cyo gukora.
Gushyiramo icyuma gitanga umuvuduko wujuje ibisabwa mu by’umutekano bikomeza kubahiriza amabwiriza ya leta ku bikorwa by’uburozi n’ibishobora gushya. Ibi bitanga amateka akomeye mu igenzura rikubiyemo ikoreshwa ryose rya ethylene-propylene rubber ndetse n’umutekano wo gutwara amazi ya ethylene.
Saba igiciro
Lonnmeter itanga uburyo bwo kohereza umuvuduko w’amazi ku murongo bwakoreshejwe mu buryo bw’ikoranabuhanga, bwakozwe ku buryo bujyanye n’ibikenewe cyane mu gukoresha rubber ya ethylene-propylene. Impuguke za Lonnmeter zitanga ubufasha mu bya tekiniki mu guhitamo uburyo bwo kohereza umuvuduko w’amazi ku murongo, bujyanye n’ibihe bikomeye by’imikorere n’ibikoresho by’amazi bifite isuku nyinshi. Hamagara kugira ngo ubone ibisubizo by’inzobere.
