Cabbiraadda cadaadiska gudaha waa aasaaska codsiyada caagga ethylene-propylene ee ku lug leh dareeraha ethylene ee cadaadiska sare leh iyopropyleneCadaadis degdeg ah oo ka dhasha uumiga cryogenic ee ku jira haanta kaydinta dareeraha ethylene ayaa kordhin kara khatarta qaraxa iyo daadashada. Xogta NIST waxay muujinaysaa in kororka 1 baar oo ka sarreeya heerka ku jira haanta kaydinta ethylene ee 50 m³ uu sii deyn karo uumiga 20+ kg ilbiriqsiyo gudahood, taasoo ka dhigaysa jawaabta waqtiga-dhabta ah mid muhiim ah.
Ku kalsoonaanta habka warshadaha caagga ah ee ethylene-propylene waxay u baahan yihiin gudbiyeyaal cadaadis dareere ah oo khadka tooska ah oo u adkaysta kororka gaaska iyo isbeddellada degdega ah ee caadiga ah ee marxaladaha falgalka iyo dhuumaha. Kala leexashada aan la kormeerin ee cadaadiska waxay horseedi kartaa badeeco aan la qorshayn ama xidhitaan aan la qorshayn, taasoo hoos u dhigaysa wax soo saarka in ka badan 5% sannadkii warshadaha qaar. Rakibaadda gudbiyaha cadaadiska ee saxda ah waxay hubisaa in wax soo saarka si sax ah loo sameeyo.ethyleneBadbaadada haanta kaydinta iyadoo la siinayo xog degdeg ah si loo xidho nidaamyada badbaadada.

Gudbiyaasha cadaadiska warshadaha sida moodooyinka Lonnmeter waxay bixiyaan saxnaanta ±0.1% FS ee ku baahsan baaxadda hawlgalka 100-500 bar ee caadiga ah ee nidaamyadan. La socodka cadaadiska inta lagu jiro gaadiidka dareeraha ethylene wuxuu ka ilaaliyaa daadashada iyo cadaadiska xad-dhaafka ah - sababaha ugu waaweyn ee dhacdooyinka khatarta ah ee qaybta. Cabbiraadda khadka gudaha ee adag waxay taageertaa hawlgal ammaan ah oo joogto ah waxayna sare u qaadaysaa wax soo saarka deegaannada isbeddelaya.
Hordhac
Cabbiraadda cadaadiska gudaha waxay bixisaa jawaab celin degdeg ah oo sax ah oo lagama maarmaan u ah xakamaynta copolymerization-ka caagga ethylene-propylene. Dareeraha ethylene ee cadaadiska sare leh iyo propylene waxay u baahan yihiin xuduudo cadaadis adag inta lagu jiro wareejinta iyo falcelinta. Isbeddellada degdegga ah ee cadaadiska haanta kaydinta dareeraha ethylene - badanaa ka yimaada uumiga cryogenic - waxay kicin karaan isku-xidhka badbaadada ama cillado masiibo ah haddii aan isla markiiba la ogaan. Badbaadada haanta kaydinta Ethylene waxay ku tiirsan tahay akhrin joogto ah si looga ilaaliyo daadashada iyo cadaadiska xad-dhaafka ah. Gudbiyaha cadaadiska khadka tooska ah ee Lonnmeter ee dareerayaasha ayaa la socda isbeddelladan waqtiga dhabta ah, si sax ah u muujinaya xaaladaha habka. Gudbiyeyaasha cadaadiska warshadaha waxay ilaaliyaan cabbir deggan inkastoo gariirka, dahaarka, ama uumiga ay caadi u yihiin warshadaha caagga ethylene-propylene. Rakibaadda gudbiyaha cadaadiska saxda ah waxay yareysaa qulqulka qalabka iyo faragelinta calaamadaha, iyadoo taageerta u hoggaansanaanta iyo ka hortagga shilalka. Cabbiraadda gudaha waxay ilaalisaa shaqaalaha, hantida, iyo hufnaanta badeecada inta lagu jiro gaadiidka iyo kaydinta dareeraha ethylene, iyadoo hubinaysa hawlgal aan kala go 'lahayn dhammaan codsiyada caagga ethylene-propylene.

Guudmarka Geedi socodka Warshadaha
Dareeraha Ethylene waxaa lagu cadaadiyaa 5–15 MPa waxaana lagu shubaa tuubooyin leh propylene iyadoo loo marayo fal-galayaal u gaar ah ethylene-propylene.cinjirCodsiyada. Gudbiyaasha cadaadiska warshadaha, sida gudbiyaha cadaadiska khadka tooska ah ee Lonnmeter ee dareerayaasha, waxay xaqiijiyaan heerka quudinta saxda ah si loo ilaaliyo astaamaha copolymer. Taangiyada kaydinta dareeraha Ethylene waxay isticmaalaan dahaarka faakuumka laba-geesoodka ah, iyagoo yareynaya socodka kulaylka ka hooseeya 0.022 W/(m·K), taasoo yareynaysa khataraha dab-shidka kulaylka. Rakibaadda gudbiyaha cadaadiska khadka tooska ah waa qasab dhammaan taangiyada kaydinta ethylene si loo suurtogeliyo daadashada degdegga ah iyo ogaanshaha kororka cadaadiska, iyadoo la taageerayo badbaadada gaadiidka dareeraha ethylene iyo hufnaanta quudinta falgalka. Kala-soocidda qaboojinta iyo gaaska waxay hubinayaan bartilmaameedyada uruurinta propylene inta u dhaxaysa 35-70%, iyagoo bixinaya xaalado ugu wanaagsan falcelinta copolymerization. Isku-darka caagga ethylene-propylene ee la dhammeeyay ayaa la wareejiyaa oo lagu kaydiyaa 0.8-1.1 MPa, iyadoo la kormeerayo si joogto ah si looga hortago khataraha uumiga iyo ilaalinta isku halaynta walxaha warshadaha caagga ethylene-propylene.
Caqabadaha Cabbirka Cadaadiska Gudaha
Dareeraha ethylene ee cryogenic ee ku jira haamaha kaydinta ee laba-geesoodka ah, oo faakuum ku dahaaran ayaa soo bandhigaya nidaamyada gudbiyaha cadaadiska dareeraha ee khadka tooska ah ee isbeddello cadaadis degdeg ah. Isbeddellada uu keeno uumiga ayaa ka badan 25 bar/daqiiqo dhacdooyinka kacsan, taasoo u baahan gudbiyeyaal leh waqtiyo jawaab celin milise ilbiriqsi ah. Badbaadada haamaha kaydinta Ethylene waxay ku xiran tahay cabbirka khadka tooska ah ee 24/7, maadaama luminta dahaarka ama soo-gaadhista ilaha kulaylka ay horseedi karto cadaadis khatar ah daqiiqado gudahood. Gaasaska milmay iyo propylene falceliyay ee codsiyada caagga ethylene-propylene waxay keenaan xasillooni darro ku meel gaar ah, oo ay ku jiraan kor u kaca dareemayaasha ilaa ±1% oo buuxa, taas oo adkeyneysa xakamaynta habka. Gudbiyeyaal cadaadis warshadeed waxay la kulmaan faragelin ka timaadda dahaarka habka, gariirka, iyo uumiga, taas oo hoos u dhigta saxnaanta dareemayaasha 0.5% ama ka badan waxayna yareysaa cimriga. Rakibaadda gudbiyaha cadaadiska ee warshadaha caagga ethylene-propylene waxay u baahan tahay fiilooyin adag iyo guryo u adkaysta cimilada, maadaama heerkulka deegaanku uu inta badan ka badan yahay 45°C heerarka gariirkuna ay gaarayaan 5 g. Habraacyada badbaadada gaadiidka dareeraha ah ee Ethylene waxay u baahan yihiin jawaab celin degdeg ah oo ka timaadda gudbiyeyaasha cadaadiska khadka tooska ah ilaa qufullada badbaadada, maadaama daadashada iyo cadaadiska xad-dhaafka ah ee khadadka wareejinta ay samayn karaan isku-darka qarxa ilbiriqsiyo gudahood.
Faa'iidooyinka Isku-darka Gudbiyaasha Cadaadiska Gudaha
Akhrinta cadaadiska waqtiga-dhabta ah ee ka imanaya gudbiyaha cadaadiska khadka tooska ah ee dareerayaasha waxay suurtogal ka dhigaysaa xakamaynta wareegga xiran ee degdegga ah inta lagu jiro isku-darka caagga ethylene-propylene. Cabbiraadaha khadka tooska ah waxay yareeyaan khatarta falcelinta baxsashada ee falgallada ka kooban dareeraha ethylene ee la cadaadiyay iyo propylene, taasoo hoos u dhigaysa xidhitaanka aan la qorshayn ilaa 32% (ICIS, 2024).
Daadashada degdegga ah iyo ogaanshaha cadaadiska xad-dhaafka ah ee haamaha kaydinta dareeraha ethylene iyo dhuumaha habka ayaa soo gaabinaysa waqtiyada jawaabta. Jawaab celinta dareemayaasha tooska ah waxay kicisaa isku xirnaanta badbaadada ka hor inta aan la gaarin xadka khatarta ah, taasoo muhiim u ah badbaadada haamaha kaydinta ethylene. Cilmi-baaristu waxay muujinaysaa in faragelinta degdegga ah ay ka hortagto 60% dhacdooyinka sii deynta ee suurtagalka ah (Horumarka Badbaadada Habka, 2025).
Maareynta habka otomaatiga ah waxaa lagu gaaraa iyadoo la adeegsanayo gudbiyeyaasha cadaadiska warshadaha meelaha muhiimka ah. Kuwani waxay yareeyaan faragelinta hawlwadeennada waxayna awood u siinayaan otomaatigga habka oo dhan ee warshadaha caagga ah ee ethylene-propylene. Warshaduhu waxay soo sheegaan hoos u dhac 17% ah oo ku yimid soo noqnoqoshada hagaajinta gacanta iyadoo la adeegsanayo dareemayaal habboon (Chem. Eng. J., 2024).
Xogta saxda ah ee cadaadiska waxay yareysaa khasaaraha dareeraha ethylene inta lagu jiro kala-soocidda, wareejinta, iyo kaydinta. Dhirtu waxay kordhisaa wax-soo-saarka agabka 4-8%, taasoo si weyn hoos ugu dhigaysa kharashyada hawlgalka.
Rakibaadda gudbiyaha cadaadiska ee buuxisa heerarka amniga ee muhiimka ah waxay ilaalinaysaa u hoggaansanaanta heerarka dowladda ee hawlgallada sunta ah iyo kuwa guban kara. Tani waxay abuurtaa diiwaan adag oo loogu talagalay baaritaannada daboolaya dhammaan codsiyada caagga ah ee ethylene-propylene iyo badbaadada gaadiidka dareeraha ah ee ethylene.
