Condensate igesi

Ulwelo hydrocarbon umxube (zonke lwesakhiwo ezahlukeneyo ezahlukeneyo ezinto eziphilayo uphekele kwiqondo lobushushu eliphezulu) ukuba ayaphuma njengokuba ngu-kwimveliso condensate, amasimi igesi kunye neoli bamanyene phantsi kwegama jikelele - condensates igesi. Yenziwe ngoobani kunye nobungakanani zabo baxhomekeke indawo neemeko gesi, ke ziyahluka ngaphakathi kwemida ububanzi. Noko ke, zingakotshwa zohlulwa ngokwendidi ezimbini:

• izinzile igesi condensate ngohlobo amaqhekeza ipetroli-separafini (kunye ubunzima molekyuli ilungu oyile engamanzi amaxesha ngaphezulu)
• imveliso ezingazinzanga, leyo, ngaphandle C5 kunye hydrocarbon eziphezulu, hydrocarbon sukube ke ngohlobo iqhezu methane-butane.

Ulweliso liphuma iindidi ezintathu amaqula, yona:

1. I-oli ekrwada (oko ngohlobo igesi ezinxulumene, nto leyo kulala ngaphantsi komhlaba ngokwahlukileyo oli ekrwada (maleko) okanye zichithakala nje kuyo).
2. igesi Dry yendalo (ephawuleka ezinomthamo phantsi hydrocarbon zichithakala nje kuyo, isivuno sezantsi kwesikhundla condensate).
3. igesi yendalo emanzi (akhutshwa gesi-condensate kwaye utyebile ipetroli condensate).

Isixa macandelo lulwelo yeegesi zendalo iyahluka ukusuka 0.000010 ukuya 0.000700 m³ nganye 1 m³ yigesi. Umzekelo, ibhate condensate igesi amasimi ezizinzileyo ezahlukeneyo:

• Vuktylskoye (Komi) - 352,7 g / m³;
• Urengoiskoye (West eSiberia) - 264 g / m³;
• Gazlinskoe (Middle Mpuma) - 17 g / m³;
• Shebelinske (Ukraine) - 12 g / m³.

condensate Irhasi yendalo ngumxube multicomponent of hydrocarbon ezahlukeneyo ulwelo kunye ezixineneyo ephantsi, apho amacandelo sukube akhoyo. Oku incitshisiwe ukusuka igesi crude ngexesha lobushushu nciphisa ngexesha wokugrumba (ngezantsi umbethe ingongoma hydrocarbon). Lowo udla ngokubizwa nje ngokuba 'amafu "okanye" ipetroli wemvelo ".

Scheme yahlukanisa condensate ukusuka igesi yendalo okanye oyile zahlukene kwaye zixhomekeke intsimi indawo iimveliso. Ngokuqhelekileyo, kwisikhululo imveliso sakhiwe kufuphi yegesi okanye yegesi condensate, irhasi eveliswayo ukulungele ukuthutha: amanzi ezahlulwe into ihlanjululwa kangangoko elithile ukusuka khompawundi sulphur bathuthwayo ukuya C1 hydrocarbon abathengi kunye ne-C2, abancinane inani labo (ukusuka geni) ezimpontshelwa kwi njengokuzibuza ukuba ukugcina uxinzelelo. Iqhezu ekude (emva kokuba ukususwa ngenxa yolo amacandelo C3, kodwa ezinomthamo encinane kubo) yeyona condensate negesi, apho kuthunyelwa ibe feed thelekela izicokisi okanye ufakelo petrochemical yokuqaphela. Ihanjiswa yi imibhobho okanye izithuthi itanki.

Le condensate igesi lisetyenziswa izicokisi njenge ekrwada ukuba imveliso zepetroli kunye nenombolo octane eliphantsi izinto kukwandisa anti-ndinkqonkqoza ongeziweyo zisetyenziswa. Ngaphezu koko, imveliso unalo ephakamileyo ilifu, ugalele ingongoma, ngoko ke ezisetyenziselwa ukubasa ehlotyeni. Njengoko diesel condensate gas esetyenziswa ayifane kuba ifuna dewaxing olongezelelweyo. Oku kusebenzisa ngaphantsi kwe kwisithathu condensates zaveliswa.

Isisombululo zeteknoloji kakhulu umdla kukuba ukusebenzisa imveliso ezifana iqhezu ebanzi hydrocarbon ukukhanya ukuya petrochemical yokuqaphela. Ulungiselele yayo uqalisa kuqhutywe condensate igesi. iinkqubo ejulile bayaqhubeka Ufakelo pyrolysis apho kweLPG sikude isetyenziswa njenge ekrwada ukuze bafumane monomers ezibalulekileyo ezifana ezifana ethylene, propylene, kunye nezinye iimveliso ezininzi ehamba eziphathekayo. Emva koko ethylene sibhekiswe izixhobo polymerization, oko lufumaneka kumabakala polyethylene ezahlukeneyo. Isiphumo wafumana ezinepolypropylene propylene polymerization. Butylene-butadiene iqhezu isetyenziselwa ukwenziwa ngerabha. C6 kunye hydrocarbon eziphezulu izinto ekrwada ekuveliseni petrochemical amagama (benzene ilungiswe), kwaye kuphela iqhezu le C5, nto leyo izinto ekrwada ukuze bafumane iimveliso ezixabisekileyo de kusetyenziswa okungafanelekanga.
