Qeexida iyo Heerarka Nadiifinta ee Sare-NadiifnimadaMethane

Nadiifin saremethanewaxaa loola jeedaa gaaska methane oo nadiif ahaan aad u sarreeya. Guud ahaan, methane oo leh nadiif ah 99.99% ama ka sareeya ayaa loo qaadan karaa daahir-saremethane. Qaar ka mid ah codsiyada adag, sida warshadaha elektiroonigga ah, shuruudaha nadiifinta ayaa laga yaabaa inay gaaraan 99.999% ama xitaa ka sareeya. Nadiifintan sare waxaa lagu gaaraa iyada oo loo marayo nadiifinta gaaska adag iyo teknoolojiyadda kala soocida si meesha looga saaro wasakhda sida qoyaanka, carbon dioxide, carbon monoxide, hydrogen, iyo qaybaha kale ee gaaska.

Meelaha laga isticmaalo methane-nadiifinta sare

Warshadaha elektiroonigga ah,methane nadiif ah oo sarreeyawaxaa loo isticmaalaa sidii gaas etching ah iyo walxo ceeriin ah oo loogu talagalay kaydinta uumiga kiimikada (CVD) ee wax soo saarka semiconductor. Tusaale ahaan, in Plasma etching, methane waxaa lagu qasaa gaas kale si ay si sax ah u xoqin qalabka semiconductor, samaynta qaabab wareeg oo yaryar. CVD,methanewaxay siisaa il kaarboon ah oo loogu talagalay kobcinta filimada khafiifka ah ee kaarboon-ku-salaysan, sida filimada silikoon carbide, kuwaas oo door muhiim ah ka ciyaara hagaajinta waxqabadka iyo xasilloonida aaladaha semiconductor.

Walxaha Kiimikada Ceyriinka:Methane nadiif ah oo sarreeyawaa walxo ceeriin ah oo muhiim u ah isku dhafka kiimikooyin badan oo qiimo sare leh. Tusaale ahaan, waxay la falgali kartaa koloriin si ay u soo saarto xeryahooda chloromethane sida chloroform, dichloromethane, trichloromethane, iyo carbon tetrachloride. Chloromethane waa walxo ceeriin ah oo loogu talagalay soo saarista xeryahooda organosilicon, dichloromethane iyo trichloromethane ayaa caadi ahaan loo isticmaalaa sida dareeraha, kaarboon tetrachloride ayaa mar loo isticmaali jiray dab daminta, laakiin isticmaalkeedu hadda aad ayuu u xaddidan yahay saameyntiisa ozone-ka. Intaa waxaa dheer,methanewaxaa loo rogi karaa syngas (isku-dar ah kaarboon monoxide iyo hydrogen) iyada oo loo marayo dib-u-habaynta falcelinta, iyo syngas waa walxo asaasi ah oo ceeriin ah oo loogu talagalay soo saarista methanol, ammonia synthetic, iyo waxyaabo kale oo kiimiko ah oo badan.

Qaybta tamarta: Halka methane caadiga ah (gaaska dabiiciga ah) uu yahay ilaha tamarta aasaasiga ah,methane nadiif ah oo sarreeyasidoo kale waxay door ka ciyaartaa codsiyada tamarta gaarka ah qaarkood. Tusaale ahaan, unugyada shidaalka, methane-nadiifinta sare leh ayaa loo isticmaali karaa shidaal ahaan, iyada oo dib u habeyn lagu sameeyo si loo soo saaro hydrogen, taas oo awood u leh unugyada shidaalka. Marka la barbar dhigo shidaalka dhaqameed ee soo jireenka ah, unugyada shidaalka isticmaalaya methane saafiga ah ayaa sare u qaadaya waxtarka tamar sare iyo hoos u dhigida qiiqa wasakhaysan.

Diyaarinta gaasaska caadiga ah:Methane nadiif ah oo sarreeyawaxaa loo isticmaali karaa sida gaaska caadiga ah ee cabbirka qalabka falanqaynta gaaska. Tusaale ahaan, chromatograph gaas, adoo isticmaalayamethane nadiif ah oo sarreeyagaaska caadiga ah ee feejignaanta la yaqaan wuxuu qiyaasi karaa dareenka ogaanshaha qalabka iyo saxnaanta, hubinta natiijooyinka falanqaynta saxda ah ee la isku halayn karo ee gaasaska kale.
