Bethe e nang le metsi ke eng?

A bethe e nang le metsi ke mokgoa o kenyeletsang ho fanyeha dikarolwana tse tiileng boemong bo tshwanang le mokedikedi, hangata ka ho budulela moya kapa kgase botlaseng ba setshelo. Sena se etsa bethe ea likaroloana tse ntseng li sisinyeha 'me li na le litšobotsi tsa mokelikeli le khase. Libethe tse nang le metsi li sebelisoa hangata lits'ebetsong tsa indasteri joalo ka tlhahiso ea lik'hemik'hale, ho hloekisa oli le ho fehla motlakase.

Khopolo ea ho ntša metsi e ile ea qala ho fumanoa lilemong tsa bo-1930 ke moenjiniere oa Brithani ea bitsoang Lewis Fry Richardson, ea ileng a hlokomela hore lehlabathe le itšoara joaloka mokelikeli ha le fefoloa ke moea. Lilemong tsa bo-1940, rasaense oa Lejeremane Fritz Winkler o ile a hlahisa mochine oa pele oa bethe oa metsi bakeng sa tlhahiso ea peterole ea maiketsetso.

Libethe tse nang le metsi li na le melemo e mengata ho feta li-reactors tse tloaelehileng tsa bethe, ho kenyelletsa le mocheso o ntlafetseng le phetisetso ea bongata, litekanyetso tse eketsehileng tsa ho itšoara, le taolo e betere ea mocheso le khatello. Boitšoaro bo kang ba mokelikeli ba likaroloana bo boetse bo fokotsa kotsi ea libaka tse chesang kapa libaka tse shoeleng, tse ka bakang liketso tse sa sebetseng kapa tse sa fellang.

Moetso oa mantlha oa bethe e nang le metsi o entsoe ka sets'oants'o kapa sejana se tlatsitsoeng ka lintho tse thata, hangata e le ntho ea granular joalo ka lehlabathe, limestone, kapa likaroloana tsa catalyst. Joale moea kapa khase e hlahisoa ho tloha ka tlaase ho setshelo, ho etsa hore ho be le mokelikeli o phahamisang le ho emisa likaroloana tse moeeng.

Ha mokelikeli o ntse o phalla ka betheng, o etsa hore likaroloana li tsamaee le ho thulana, ho etsa hore ho be le phello e matla ea ho kopanya le ho kopanya. Ho sisinyeha hona ho boetse ho pepesa likaroloana sebakeng se seholoanyane, ho lumella mocheso o sebetsang hantle le ho fetisa boima pakeng tsa likaroloana le mokelikeli o potolohileng.

E 'ngoe ea melemo ea bohlokoa ea libethe tse nang le metsi ke bokhoni ba bona ba ho laola mocheso oa karabelo. Ka ho fetola sekhahla sa phallo le mocheso oa mokelikeli, basebetsi ba ka boloka mocheso o tsitsitseng ho pholletsa le bethe, ho thibela libaka tse chesang le ho etsa bonnete ba hore karabelo e tsoela pele ka tekanyo e nepahetseng.

Libethe tse nang le mokelikeli hangata li sebelisoa ha ho etsoa lik'hemik'hale, joalo ka tlhahiso ea ammonia, methanol, le lik'hemik'hale tse ling tsa petrochemical. Li boetse li sebelisoa ho lokisa lijo le meriana, hammoho le ho hloekisa metsi a litšila le litšila tse ling tsa indasteri.

Indastering ea ho fehla matla, libethe tse nang le metsi li sebelisoa ha ho chesoa mashala le libeso tse ling tsa khale. Ts'ebetso ena e kenyelletsa ho chesa mafura ka betheng e nang le metsi a mokoetla, e kopanang le sulfur dioxide e hlahisoang nakong ea mollo ho etsa calcium sulfate (gypsum). Ts'ebetso ena, e tsejoang e le ho tuka ha bethe ea metsi, e fokotsa ho ntšoa ha sulfur dioxide le lintho tse ling tse silafatsang tse amanang le lifeme tse tloaelehileng tsa mashala.

Qetellong, libethe tse nang le metsi ke theknoloji e ncha e nang le mekhoa e mengata e nang le lisebelisoa tse ngata tsa indasteri. Ba fana ka mocheso o ntlafetseng le phetisetso ea boima, litekanyetso tse eketsehileng tsa karabelo, le taolo e ntle ea mocheso le khatello. Li sebelisoa liindastering tse fapaneng, ho kenyelletsa tlhahiso ea lik'hemik'hale, tlhahiso ea motlakase, ho lokisa lijo le ho hloekisa metsi a litšila.
