Amakhemikhali Okukhiqiza
I-ejenti Yokunciphisa Ukuhudula
Ingxube Yokugcoba ye-ROP
I-Drag Reducing Agent (ebizwa ngokuthi i-DRA) ingachazwa njenge-poly-alpha-olefin enesisindo sama-molecule esiphezulu kakhulu ngezindlela zempuphu ecolekileyo elenga esisekelweni soketshezi. I-DRA yenzelwe ukwandisa izinga lokugeleza noma ukunciphisa ukusetshenziswa kwamandla (ukwehla kwengcindezi) emipayipini kawoyela ngokunciphisa ukuqhuma okunamandla.
Imikhiqizo yethu ye-DRA isetshenziswe emithanjeni eminingi kakhulu futhi kutholakale ukunciphisa okukhulu kokuhudula noma ukwanda kokugeleza. Ngezansi kunezimo zokusetshenziswa ezingu-7 kwezingaphezu kwe-100. Lezi zimo ezingu-7 zingaba ezikhethekile ezihilelekile ezimweni zokusebenza kwemithanjeni eziyinkimbinkimbi/ezimbi kakhulu noma amaphrofayili emithanjeni, okuhloswe ngazo ukukhombisa ukuthi i-DRA isebenza kanjani ngaphansi kwalezi zimo eziyinkimbinkimbi/ezimbi kakhulu futhi ngaleyo ndlela kutholakale ukuthi i-DRA izosebenza kangcono kakhulu ngaphansi kwezimo ezijwayelekile.

Isingeniso somkhiqizo
I-UBPro-471 iyi-ejenti yokunciphisa ukudonswa (i-DRA ngamafuphi).
▶Yakhelwe ukwandisa izinga lokugeleza noma ukunciphisa ukwehla kwengcindezi emapayipini aletha uwoyela ongahluziwe.
▶Njenge-polyalphaolefin enesisindo sama-molecule esiphezulu kakhulu esakazeke ku-base/carrier engeyona emanzi. Ukunciphisa ukuhudula kuqala ngokushesha nje lapho i-DRA iqala ukuncibilika ku-hydrocarbon ehanjiswayo.
▶Uma umkhiqizo we-DRA oncibilikisiwe udlula empompini yokukhulisa, i-polymer iyaphuka noma iguge ngenxa yokucheba okwenziwa yipompo yokukhulisa. Ngenxa yalokho, ipayipi elinezindawo eziningi ngokuvamile lidinga ukujova i-DRA okuphindaphindiwe ngemva kwesiteshi ngasinye sepompo yokukhulisa ukuze kufezwe ukwanda kokugeleza okuphelele kulo lonke ubude bepayipi.
▶Akuwohloki ngesikhathi sokugeleza okuvamile kwepayipi, kodwa kuklanyelwe ukonakala lapho kudlula kumaphampu amakhulu noma kwezinye izindawo ezigunda kakhulu. Lokhu konakala kokugunda kuqeda isidingo sokucubungula uwoyela ophathwe kahle kude nomfula.

Izinhlelo zokusebenza/Imisebenzi
▶Isetshenziswa embobeni yokushisa ebanzi esukela ku--20 kuya ku-+50℃.
▶Incibilika ngokushesha kuma-hydrocarbon, amazinga okugeleza ayanda.
▶Isikhathi sokuphila esinde sepayipi.
▶Ukusetshenziswa kwamandla okuncishisiwe
Izinzuzo
▲ Finyelela ukunciphisa okungaphezu kuka-70% ngaphansi kwezimo ezithile
▲ Izinga lokushisa eliphansi (-20 ℃):I-Propylene Glycolthuthukisa ukugeleza kwesinciphisi sokudonsa emazingeni okushisa aphansi (njengokuvimbela ukubanda) futhi uthuthukise ukuzinza okuphelele kwefomula.
▲ Phatha bese ufaka epayipini kalula futhi ngaphandle kwezingozi zokuphepha eziphansi
▲ Khulisa ukugeleza kwepayipi ezingeni lokushisa elifanayo lokusebenza
▲Kuthuthukisa umthamo wombhobho ngaphandle kokutshalwa kwezimali
Ukuphathwa Okunconyiwe
▶Izinga lomjovo lincike ku: ukusebenza okudingekayo, ukuqina, okuqukethwe yi-wax/amanzi kawoyela, njll.
▶Indawo yokujova iphakathi kwesiteshi lapho i-metering skid kanye nepayipi langaphandle lingena khona emhlabathini. Lokhu kungagwema ukunqunywa kwe-impeller yangaphandle yepompo kanye nesenzo sokuvimba nokushukumisa se-flow meter. Futhi i-ejenti yokunciphisa ukudonsa inebanga elanele lokuhlangabezana nezidingo zesikhathi sokuhlakazeka. I-DRA injection skid ifaka amaphampu okujova, amamitha okugeleza, kanye nama-pressure gauges. I-pneumatic chemical agent injection pump isetshenziselwa ukwethula umoya wethuluzi njengomthombo wamandla.
▶Umthamo onconywayo uyadingeka ukuze uthole imiphumela emihle kakhulu ngokuhlolwa kokuhlola.
▶Bonke abasebenzi abaphatha le nto kumele bayiphathe njengekhemikhali yezimboni, bagqoke imishini yokuzivikela futhi balandele izinyathelo zokuphepha njengoba kuchaziwe ku-Material Safety Data Sheet (MSDS).
Ukupakishwa Nokugcinwa
I-IBC engu-1000L. Ukunikezwa kwezinye izinto zokupakisha ezifana namathangi e-ISO kunganikezwa uma kuceliwe.
Gcina endaweni eyomile, enomoya omuhle. Gcina isitsha sivaliwe. Landela imikhuba ephephile yokugcina izinto mayelana nokufaka ama-pallet, ukubopha, ukusonga ngokunciphisa kanye/noma ukuhlanganisa.

Iza kanjani iDrag Force?
Uwoyela uphusha phezulu odongeni lwangaphakathi lwepayipi, ipayipi liphusha uwoyela phansi libangele ukuzulazula komoya okudala amandla okuhudula. Uma i-polymer ingeziwe, ixhumana namafutha kanye nodonga ukusiza ukunciphisa ukuthintana kwamafutha nodonga.

Ama-ejenti okunciphisa ukuhudula (i-DRA)
Ama-ejenti okunciphisa ukuhudula (i-DRA) noma ama-polymer anciphisa ukuhudula (i-DRP) ayizithasiselo kumapayipi anciphisa ukuxokozela epayipini. Ngokuvamile asetshenziswa kumapayipi kaphethiloli, andisa umthamo wamapayipi ngokunciphisa ukuxokozela nokwandisa ukugeleza kwe-laminar.

ukuthi isebenza kanjani: Izinciphisi Zokudonsa Amapayipi
Ubufakazi buncike ekusebenzeni kwawo kahle ngenxa yama-polymer anesisindo sama-molecule amaningi, angama-compound ama-hydrocarbon aneketanga elide. Lawa ma-polymer asebenza njengezithibi zokuphazamiseka odongeni lwepayipi, ehlisa amandla alahlekayo emsebenzini oguquguqukayo.

Ukukhethwa kanye Nokusetshenziswa Kwezinciphisi Zokudonsa
Ukukhetha isinciphisi sokuhudula esifanele kudinga ukucabangela izici eziningi, okuhlanganisa izakhiwo zoketshezi (isb., ukujiya, ukwakheka), izimo zokusebenza kwamapayipi (isb., izinga lokushisa, ingcindezi), kanye nezici zemvelo. Ngaphezu kwalokho, ukuhlushwa komjovo kanye nendlela yokunciphisa ukuhudula kufanele kulungiselelwe ngokusekelwe ezimweni ezithile ukuqinisekisa ukusebenza kahle kokunciphisa ukuhudula kanye nezinzuzo zomnotho.

Intuthuko Yezobuchwepheshe
Njengoba ubuchwepheshe bokuthuthwa kwamapayipi buthuthuka, ucwaningo kanye nokusetshenziswa kwezinciphisi zokuhudula kuyaqhubeka nokukhula. Njengamanje, abacwaningi basebenza ukuthuthukisa izinciphisi zokuhudula ezisebenza kahle futhi ezinobungani nemvelo ukuze zihlangabezane nezidingo zezinhlobo ezahlukene zoketshezi kanye nezimo zokusebenza eziyinkimbinkimbi. Kodwa-ke, ukusebenza kwezinciphisi zokuhudula kuthonywa kakhulu yizimo zamapayipi, okudinga ukuhlolwa kwensimu kanye nokuhlolwa ukuqinisekisa ukusebenza kahle kwazo kanye nokuphila kahle kwezomnotho.

Ama-polymer anciphisa ukuhudula
Izinkampani zokukhiqiza i-oyili ngokuvamile zisebenzisa amaphampu angaphandle kanye namapayipi ukuthutha uwoyela ongahluziwe. Njengoba ukwanda kokukhiqizwa kanye nokugqwala kwamapayipi, izici zezinhlelo zamapayipi zishintshile.
Izinkambu eziningi zikawoyela zisebenzisa ama-ejenti okunciphisa ukudonsa emapayipini kawoyela. Khulisa ukudluliselwa kwepayipi kawoyela ongahluziwe ngokufaka ama-ejenti okunciphisa ukudonsa. Lokhu kungenxa yentuthuko esheshayo yobuchwepheshe bamapayipi ukuze kuncishiswe ukudonsa nokwandisa ukudluliselwa. Lokhu kungahlangabezana nezidingo zokwandisa umkhiqizo ngesikhathi esifushane. Futhi ngeke kukhulise izindleko zokutshalwa kwezimali.
Umthamo wokukhiqiza wensimu kawoyela eMpumalanga Ephakathi unqunyelwe yipayipi kawoyela. Kuhlelwe ukunciphisa ingcindezi yangaphandle ngokusebenzisa indlela yokufaka ama-ejenti okunciphisa ukudonsa epayipini kawoyela. Lokhu kudinga ukuhlolwa kwendawo ensimini. Ukuhlola i-ejenti yokunciphisa ukudonsa ngale ndlela. Isisekelo siwukuqala sinqume ukuthi isimo sokugeleza koketshezi siyahlangabezana yini nobubanzi obufanele be-drag reducer. Ukubala isikhathi sokusabalala kwe-DRA. Nquma ngokunembile iphuzu lokujova le-ejenti yokunciphisa ukudonsa.
Lokhu kubangela ukuthi iphampu yangaphandle yehluleke ukuletha uwoyela ongahluziwe ngesikhathi ngokwevolumu elinganisiwe. Njengamanje, ukusetshenziswa kwezinto ezinciphisa ukudonsa emapayipini kawoyela kuthuthuka ngokushesha. Ekukhiqizweni kwensimu kawoyela, ukufakwa kwezinciphisi zokudonsa kusetshenziselwa ukunciphisa ukulahlekelwa kokwehla kokucindezela nokwandisa umkhiqizo wepayipi.
Kuze kube manje, akukho sinciphisi sokudonsa esisebenza kuzo zonke izinhlobo zikawoyela ongahluziwe. Kodwa-ke, ucwaningo olunzulu luholele ezicini eziningana ezibalulekile zokukhetha i-ejenti yokunciphisa ukudonsa efanele (i-DRA):
Ukusebenza kahle ekugxileni okuphansi: Ama-DRA kufanele asebenze kahle ngamanani amancane, njengoba ukufakwa kwawo okuqhubekayo oketshezini lwepayipi kudinga inani elikhulu ngokuhamba kwesikhathi. I-DRA esebenza kahle kakhulu ngamanani aphansi isiza ukunciphisa izindleko zezimali ngenkathi iqinisekisa ukusebenza okuqhubekayo.
Ukuhambisana Nezinqubo Zokuhlanza: I-DRA ekhethiwe akufanele ilethe izinkinga emisebenzini yokucwenga engezansi komfula. Ukuthuthukisa ukudlula kwamapayipi akusebenzi uma ukungcola kungenakucutshungulwa kahle yizikhungo ezikhona.
