Liquid-methane: izici futhi izicelo

Ngaphambili, iNkampani ukucutshungulwa uwoyela baphoqeleka ukuba ashise methane ketshezi bekhanyise ngezibani ziye bengakwazanga ukudlula condensate okwalandela Petrochemical ukucubungula. Manje wafunda uyiswe futhi asetshenziswa ezimbonini eziningi. Ngakho it is kahle agcinwe futhi ingeyona ngesikhathi omlilo of ukungcola okuyingozi.

Izakhiwo kanye amakhemikhali methane

Methane iyona hydrocarbon elula libhekisela. Kuyinto alula kakhulu kunomoya emoyeni, akuyona anobuthi, kuyinto kahle oncibilikayo emanzini, ayinakho nephunga lubonakale. Kukholakala ukuthi i-methane ingozi kubantu, kodwa amacala zaziwa ka nemiphumela yayo ephakathi autonomic nesimiso sezinzwa. Yebo, ukuqongelela endlini emoyeni at lokuhlushwa kusuka 4% kuya 17% iba alufakwa. Ngakho-ke, ngenxa ukutholakala lomuntu wakhe (ngaphandle amathuluzi) ukuze i-methane ngokuvamile wanezela into ekhethekile, kepha efaniswe isimdubula. Libhekisela amagesi abamba ukushisa. I-methane buthaka izakhiwo kwezidakamizwa ukuthi buthaka solubility ongaphakeme emanzini.

Ngu imvelaphi, zezakhi okuholela nge ezihlukahlukene izinto futhi zamakhemikhali uhlukaniswe:

• Biogenic (organic);
• abiotic (wezinto);
• amagciwane (nezilwanyana ezincane);
• thermogenic (izinqubo thermochemical).

Njengoba yenziwe ukuthi le gesi futhi endaweni yokucwaninga ngokubeka amalahle anhydrous soda lime noma sodium hydroxide nge acetic acid, eqandisiwe.

Methane esimweni liquid ithatha umthamo izikhathi 600 ezincane kuno kule igesi. Ngakho-ke, ezokuthutha lula futhi isitoreji it is ngaphansi liquefaction. methane Liquid - uketshezi kungekho nto enemibala emihle, abangenalo iphunga. It azigcina cishe zonke izakhiwo gas. Ezibucayi ingcindezi ketshezi methane 4,58 MPA (imiz, lapho kuba uketshezi).

Ukuba khona emvelweni

Methane eyilungu futhi indaba esemqoka ephambili we amagesi ezilandelayo:

• Natural (98%);
• uwoyela (40-90%);
• bog (99%);
• okwami (35-50%);
• izintaba-mlilo udaka (phezu 94%).

Liphinde atholakala Ukwakheka wamanzi olwandle, emachibini nasolwandle. Yethula emkhathini Earths ezinjalo, Saturn, i-Jupiter, i-Uranus ne amagesi e kobuso Moon. Inani elikhulu eziqukethwe amalahle ezivuzayo. Lokhu kwenza ukukhiqiza in penetrations avaliwe umsebenzi alufakwa.

LNG ubuchwepheshe

methane ehlanzekile lisuselwa igesi yemvelo, isusa uzime nensika nezinye izingxenye: ethane-propane, i-butane ne-nitrogen eningi. Ukuze uthole ketshezi igesi i-methane onomfutho kulandele lwaluyophola. inqubo liquefaction Kwenziwa ngemijikelezo. Kuleso naleso sigaba, ivolumu sehliselwe izikhathi ezingu-12. Njengoba kuvela ketshezi emjikelezweni odlule. Liquefaction zisebenzisa izinhlobo ezahlukene zezitshalo, phakathi kwabo:

• mpintsha;
• a turbo-jet;
• turbo olwandisa.

Amacebo ezilandelayo ingasetshenziswa:

• wendlale;
• ukunwetshwa.

Ngo wesifunda wendlale isebenzisa ezintathu Ukupholisa ejenti. Uma le-methane lokushisa liquid incipha kancane kancane. Ubuchwepheshe obunjalo kudinga dolobha imali eshisiwe. Okwamanje le nqubo kuyathuthuka futhi waqala ukusebenzisa ngokushesha ingxube refrigerants (ethane ne-propane). Leli cebo isibe self-Ukupholisa, njengoba lezi izinto etholakala kuncibilike igesi yemvelo. Izindleko kancane sehle, kodwa zisaphakeme.

Ngo isicelo amaqhinga ukunwetshwa asetshenziswa eyonga uphethiloli imishini centrifugal. Ingxube ukuthi pre-nahlanza kusukela amanzi nezinye izinto futhi uketshezi ngaphansi kwengcindezi ngenxa exchange ukushisa igesi ekusakazeni abandayo ukunwetshwa. Nokho, le nqubo idinga ukusetshenziswa kwemali enkulu amandla kunangesikhathi wendlale (25-35%). Kodwa ngesikhathi esifanayo, ukonga nemali yokuqhuba ukuze compressors nokusebenza imishini.

I lokushisa methane ketshezi ezivezwa inqubo ngenhla, okuyisilinganiso sabangu-162 degrees.

Ukusetshenziswa methane

Ububanzi methane njengoba isimo gaseous noma uketshezi, kumba eqolo. Lisetshenziswa njengendlela kubaswa ngazo umlilo, njengoba impahla eluhlaza for umkhakha, ekhaya, njengoba Anabolic steroid ngenxa yokwanda mafutha mass umzimba.

amandla omlilo Akuphelele methane ekhiqizwa carbon black okuyinto kabanzi umkhakha :. Ngo iraba, Uyinki nginyathela, upholishi wezicathulo, njll Futhi esetshenziswa ukwenziwa hydrocyanic acid acetic acid, methanol, acetylene, i-ammonia, carbon disulfide, njengoba igesi uphethiloli (i laphakade umlilo).

I-methane ketshezi isetshenziswa njengophawu fuel motor ngoba izimoto. Yena octane inombolo 15% kunakunoma uphethiloli, kanye eliphezulu calorific ukubaluleka kanye anti-knock izakhiwo. Izimpendulo ezivela methane liquid combusted cishe ngokuphelele futhi uma efakwe kahle kwi abafanele imishini imoto kwenzeka sasivumela umnotho onohlonze kuqhathaniswa uphethiloli (at eside ibanga uhambo).

Lokhu igesi ngenkuthalo esetshenziselwa yokukhiqiza izidakamizwa ukuthi ukwandisa mafutha mass umzimba. Ngezinye kwesisekelo salo ayatholakala izindlela ezifana "Dianoged", "Danabol", "Nerobolum" abakhuluphele kakhulu ziphoqa. Kukholakala ukuthi le mithi nethonya elihle ku-nomzimba womuntu:

• aqinise amathambo;
• zishukumisa kumiswa izici ngokobulili;
• ashise ungqimba amafutha;
• ukwandisa ukukhuthazela;
• ukuphuthumisa amaprotheni zamagama.

Nokho, kubalulekile ukukhumbula ukuthi zonke imithi inemiphumela ethile engemihle, ngakho kufanele kuthathwe ngaphansi kweso lwezokwelapha.

Ngokusekelwe osekushiwo, kumele kuphetfwe ukuthi ukukhiqizwa methane ketshezi kuyinto endaweni ethembisa kakhulu embonini yesimanje.
