He aha te mea he mea nui te alumina i roto i te tukanga whakaora a Claus Sulfur?
Ko nga whakakorikori alumina e whakamahia ana i roto i nga Waehanga Whakaora o Claus Sulfur e tohu ana i te karaehe whakakorikori tino matarohia me te whakamahi whanui mo tenei tono. Ko te -te parakore te konumohe whakahohe ka whakakorikori i te tauhohenga i waenga i te hauwai sulfide (H2S) me te sulfur dioxide (SO2) ki te whakaputa i te whanariki (S), i te wa e whakatairanga ana i te hauwai o te whanariki-kei roto i-nga hua penei i te warowaiwa (COS) me te waro disulfide (CS2), na reira ka piki ake te tere whakaora whanariki.
He aha te Claus Process Sulfur Recovery?
Ko te tukanga Claus tetahi o nga hangarau whakaora whanariki e tino whakamahia ana i roto i nga umanga hou. Ka whakamahia te nuinga ki te huri i te hau waikawa kei roto H2S ki te huānga S, i te whakaiti i te parahanga taiao i puta mai i te tukunga tika o te sulfide. Ko te tikanga whakaora whanariki a Claus e pa ana ki nga ahuatanga ahumahi e whakaputa ana i te nui o te whanariki -e mau ana i nga hau waikawa, penei:
* Nga mahi para hinu: ki te whakaora i te whanariki mai i nga hau waikawa ka puta i te wa e mahi ana;
* Tukatuka hau maori: ki te hamani i nga hau waikawa i puta i te wa o te whakangao hau hau maori;
* Ahumahi matū waro: ki te hamani whanariki -waikawa waikawa ka puta i te wa whakaahuru waro me te purenga syngas;
* Te Ahumahi Coking: ki te huri i te hauwai sulfide i roto i te hau umu kaokao hei whanariki;
* Ahumahi Petrochemical: ki te whakaora whanariki mai i a H2S-kei roto nga hau tukanga;
* Nga ahumahi e pa ana ki te sulfide: hei mahi i te whanariki -e mau ana nga hau para mai i te waikawa pungatara, te viscose, me te muka matū.
Kei hea te Alumina Catalyst e tuu ana i roto i te Tukatuka Claus?
Kei roto i tetahi waahanga whakaora whanariki a Claus he punaha whangai hau waikawa, oumu hau waikawa, kohu wera para, whakamaarama whanariki, Claus catalytic reactors, me te poka kohinga whanariki wai, he tank hiri whanariki ranei.
Ko te tauhohenga matua o te tukanga Claus ko te tauhohenga i waenga i a H2S me SO2ki te whakaputa i te whanariki timatanga. I roto i te mahi, he waahanga o te H2Ka wera tuatahi a S ki te whakaputa SO2; te hua SO2ka tauhohe ki te toenga H2I runga i te whakakorikori-te tauhohenga a Claus-ki te whakaputa i te kohu whanariki, ka puta he whanariki wai ina whakamatao.
No reira,Claus alumina whakakōkīka whakamahia i roto i enei reactors catalytic. A ko nga moenga whakakorikori a Claus o te ahumahi e whakamahi ana i te alumina whakahohe.
Nga Mahi a Alumiina Whakahohe i roto i te Tukatuka Claus
Te whakatiki i te tauhohenga matua a Claus. Koinei te mahi tino nui! Ki te kore he whakakōkī, ko te tere tauhohenga i waenga i a H2S me SO2he puhoi; engari, ko te konumohe whakahohe he maha nga waahi o te mata hohe, e taea ai te tauhohenga ki te whakatata tere ki te taurite i nga pāmahana e whakaaetia ana e te ahumahi.
Te whakamaarama i te hauwai COS. Hei taapiri atu ki a H2S, hau waikawa te nuinga kei roto CO2, waiwaro, me te iti o te sulfide waro. I roto i te oumu tauhohenga waiariki, ko etahi whanariki-kei roto nga pūhui waro ka hanga COS me CS2. Ko te alumina kua whakahoahohia te hurihanga o te whanariki i roto i te COS ki te H2S, ka tuku kia uru ki te punaha tauhohenga a Claus; he mea nui tenei mo te whakanui i te katoa o te reeti whakaora whanariki.
Whakapaia CS2hauwai. CS2he hua i puta mai i te maaharahara i roto i te tukanga Claus. Waiwai o CS2ka huri i te whanariki kei roto i te ngota ngota ki te H2S, ka taea e ia te whai waahi ki te tauhohenga a Claus; ko tetahi atu mahi matua o te whakakorikori alumina whakahohe.
He aha te mea e hiahiatia ana te alumina i roto i te whakaoranga o Claus Sulfur?
Mo te konumohe-a Claus catalysts, ko te mea nui ehara i te whakanui noa i te Al2O3ihirangi. Engari, me whai arotautanga matawhānui o te waahi mata motuhake, te hanganga pore, te mahi mata, me te aukati ki te whakakore.
I runga i te rereke o te rahi o te ngota ngota H2S, NA2, COS, CS2, me H2O-me te mea ko te tauhohenga a Claus ko te whakamaaramatanga o nga hau-maha i roto i nga matūriki whakakorikori-he mea nui te whakahaere i te rahi o te pore. Mēnā he iti rawa ngā kōputaputa, ka aukatihia te diffusion reactant, ka piki ake te parenga o roto, ka aukati i te whakamahi katoa o nga waahi hohe i roto i te whakakorikori. Engari, ki te nui rawa nga pores, ka heke te maha o nga waahi kaha. No reira, ka hiahiatia e nga kaiwhakatuma o Claus ahumahi he tohatoha rahi pore i hangaia, ka taea e te alumina whakahohe te whakarato i nga ahuatanga o te mata me nga hanganga pore hei whakatutuki i enei whakaritenga.
