Ulwelo methane: iimpawu kunye nezicelo

Ngaphambili, i-oyile processing Company kwanyanzeleka ukuba ukutshisa methane engamanzi esebenzisa izibane ziye khange sikwazi ukudlula condensate olulandelayo processing petrochemical. Ngoku wafunda ukuba kuhanjiswe kwaye asetyenziswe mveliso ezininzi. Ngokunjalo kubhaliwe zigcinwe kakuhle, kwaye aluyiyo ngexesha ukutshiswa ukungcola eziyingozi.

iimpawu methane Physical nemichiza

Methane lo ezizizembiwa zilula ibhekisela. Kuyinto elula komoya, ayikho ityhefu, ayiqondakali enyibilikayo emanzini, akukho ivumba buqapheleke. Kukholelwa ukuba methane akukho ayingozi ebantwini, kodwa amatyala aziwa yeziphumo yayo kwinkqubo central kunye yawo luvo. Olwenzeka ngaphakathi umoya kwi iqela ukususela nge-4% ukuya kwi-17% uba Uyadubula. Ngoko ke, ngokuba ukufunyanwa wenkqu yakhe (ngaphandle izixhobo) ukuya methane udla wongezelela into eyodwa, efana ivumba werhasi. Libhekisela greenhouse gases. I-methane iipropati buthathaka ezidakumbisayo ukuba buthathaka ukunyibilika ephantsi emanzini.

Xa imvelaphi, ezi zinto ngenxa kunye ezahlukeneyo izinto abasabela imichiza yohlulwe:

• Biogenic (organic);
• abiotic (ezingaphiliyo);
• ziibhaktheriya (kwaziwe);
• thermogenic (iinkqubo thermochemical).

Izimasekile le gesi kunye elabhoratri ngokufudumeza ekalika soda anhydrous okanye sodium hayidroksayidi nge-acetic acid, zibambene.

Methane olulwelo ohlala umthamo amaxesha 600 ezincinane ngakumbi irhasi. Ngoko ke, izithuthi lula nokugcinwa ke phantsi yokunyibilika. methane alulwelo - yinto ulwelo enemibala emihle, ukuba akukho ivumba. Igcina phantse zonke iimpawu yigesi. Critical methane engamanzi xi 4,58 MPA (min, apho iba ulwelo).

Khona endalweni

Methane ilungu yaye umbandela ongundoqo usemthethweni zegesi zilandelayo:

• Natural (98%);
• oyile (40-90%);
• Bog (99%);
• yeyam (35-50%);
• mlilo udaka (ezingaphezu kwama-94%).

Kwakhona ifumaneka ekwakhiweni lwamanzi iilwandle, amachibi neelwandle. Ekhona kule Kwimeko enjalo nemihlaba, likaSaturn, Jupiter, Uranus kunye neegesi kumphezulu iNyanga. Inani elikhulu eziqulathwe beentanda zamalahle. Oku kwenza kwezemveliso penetrations ezivaliweyo umsebenzi Uyadubula.

technology LNG

methane Pure silufumana igesi yendalo, ndihambe ndikhetha kwamanye amacandelo:-methane, propane, butane kunye nitrogen. Ukuze ufumane igesi methane ulwelo zixinaniswe kwalandelwa okupholisa. inkqubo yokunyibilika yenziwa kwimijikelo. Kwinqanaba ngalinye, umthamo zancitshiswa izihlandlo ezili-12. Njengoba kuvela ulwelo kumjikelo wokugqibela. Yokunyibilika sebenzisa iintlobo ezahlukileyo zezityalo, phakathi kwabo:

• umcephe wokunyusa;
• a kwiinqwelo-jet;
• kwiinqwelo-olwandisa.

Amacebo zilandelayo zingasetyenziswa:

• ayo;
• kwanda.

Kwisiphaluka ukuxubana usebenzisa arhente ezintathu kobubi. Xa oku lobushushu methane ulwelo kunciphisa kancinci. technology enjalo ifuna iinkcitho abakhulu. Okwangoku le nkqubo kakuhle waza waqalisa isicelo ngoko nangoko refrigerants umxube (methane kunye propane). Esi sikimu liye laba self-ukupholisa, njengoko ezi izinto zazifunyanwa irhasi yendalo kwegesi. Iindleko zehla kancinane, kodwa isahleli phezulu.

Xa isicelo kwezikim ukwanda i kusetyenziswa oomatshini centrifugal amafutha-kakuhle ngakumbi. Lo mxube livele-nyulu ngamanzi kunye nezinye izinto kwaye kwegesi phantsi koxinzelelo ngenxa exchange ubushushu kunye abandayo eyandisiweyo umsinga igesi. Nangona kunjalo, le nkqubo ifuna ukuba inkcitho enkulu yamandla ngakumbi ndachithelwa (25-35%). Kodwa kwangaxeshanye, ukonga iindleko ezinkulu ngenxa compressors kunye nokusebenza kwezixhobo.

Iqondo lobushushu methane ulwelo eziveliswa yinkqubo ngasentla, umlinganiselo degrees 162.

Ukusetyenziswa methane

Ububanzi methane njengelizwe sukube okanye engamanzi, kumba kakhulu. Oku kusetyenziswa njenge amafutha, njenge ekrwada kwishishini eziphathekayo, ekhaya, njengoko steroid ngenxa yokwanda ubunzima umzimba ezinqinileyo.

ukutshiswa engaphelelanga methane wavelisa carbon emnyama leyo lisetyenziswa kwi :. kushishino In irabha, bexhentsa i-inki, yezihlangu, njl Kwakhona ezisetyenziswa kwimveliso hydrocyanic acid kunye acetic acid, methanol, iasithilini, ammonia, carbon disulfide, njengoko igesi amafutha (esimiyo lomlilo).

I-methane ulwelo isetyenziswa amafutha motor ukuba iimoto. Yena octane inani yi-15% ngaphezulu ngaphezu koko zepetroli, kwakunye nexabiso eliphezulu calorific kunye anti-ndinkqonkqoza iipropati. Ingxelo evela methane ulwelo combusted phantse ngokupheleleyo yaye xa ifakwe kakuhle kwi izixhobo isithuthi ezichaphazelekayo kwenzeka kakuhle uqoqosho esinzima kuthelekiswa ipetroli (kwi iihambo long distance).

Le igesi belizwe zisetyenziswa Manufacturing iziyobisi ukwandisa ubunzima umzimba ezinqinileyo. Xa noseko lwalo ziyafumaneka iindlela ezifana "Dianoged", "Danabol", "Nerobolum" ngubani ezifunwa kakhulu. Bakholelwa ukuba la machiza kuba nempembelelo entle emzimbeni womntu:

• aqinise amathambo;
• ukuvuselela ukuyilwa iimpawu ngokwesondo;
• aqhumisele umaleko fat;
• ukwandisa unyamezelo;
• ukukhawulezisa protein yokuqaphela.

Nangona kunjalo, kubalulekile ukukhumbula ukuba onke amachiza zineziphumo ebezingalindelekanga, ngoko ke kufuneka athathwe phantsi kweliso zonyango.

Ngokusekelwe kule nkcazelo ingasentla, kunokwenziwa isigqibo sokuba imveliso methane ilulwelo indawo ethembisa kakhulu mboni mihla.
