Tichitarisa zviitiko zvikuru zviri kuitika mumusika wegasi rakanyungudutswa muna 2023, pane zvinhu zviviri zvinokanganisa zvakananga nheyo dzekupa nekudiwa: chekutanga, tsaona yekuchengetedzeka kweresitorendi yeNingxia; ii. Oiri yeAlkylate inobhadhariswa mutero wekushandiswa. Zviitiko zviviri zvikuru izvi zvinokanganisa misika yevashandi neye olefin carbon 4 zvakateerana.

Njodzi dzekuchengetedza dzinokanganisa zvakananga kudiwa kwegasi revanhu, kutevedzera mitemo munzvimbo iyi, kusatevedzera mitemo hakusviki pazvinodiwa nekurambidzwa, uye kune mayuniti akajairwa kuti arege musika; Zvisinei, zvinewo kukanganisa kwakaipa pakushandiswa kwegasi revanhuwo zvavo.

Kwave nemishumo yakawanda uye ongororo dzekuchinja kukuru mumusika kwakakonzerwa nemutero wekushandiswa kwemafuta ealkylate uye kuwedzera kwakanyanya kwemitengo. Mwedzi mishanu yapfuura kubva pakatanga kushandiswa mutemo uyu, uye tichatarisa kukanganisa kwakanangana nemusika wecarbon four kuburikidza nedata.

Kuburikidza nekuchinja kwekudiwa kweC4 yeolefin mumidziyo yealkylation, zvinogona kuonekwa kuti kudiwa kwacho kwakagadzikana mumwedzi wekutanga kana miviri usati watanga mitemo yakakodzera. Zororo diki muna Chivabvu raive mwaka wepamusoro wekudiwa kwemafuta, izvo zvaifanira kunge zvaive zvakanyanya pakuvaka michina yealkylation, asi mutero wekushandisa waibhadharwa pakati nepakati nepakati, uye mamwe mabhizinesi akaderedza mutoro kana kumisa basa kudzivirira njodzi, zvichikonzera kudzikira kwehuwandu hwekushanda kwealkylation uye kudiwa, uye huwandu hwekushandiswa kwesimba realkylation hwakaderera ne10 muzana munguva pfupi. Mushure menguva inosvika hafu yemwedzi yekusagadzikana, musika wealkylated oil neolefin C4 wakawanazve chiyero chitsva chekuenzanisa: mutengo weolefin C4 waderedzwa zvakanyanya.

Muna Chivabvu, mutengo we olefin carbon 4 muChina wakaderera ne11.76%, wakaramba uchidzikira ne8.84% muna Chikumi, uye wakawedzera muna Nyamavhuvhu; Purofiti ye alkylation yaive yakakwira muchikamu chekudzikira kwegasi rezvinhu zvisina kugadzirwa, asi purofiti yakaderera zvishoma nezvishoma nekutanga kwemutero munguva yekupedzisira, uye yakadzoserwa muna Nyamavhuvhu, mushure mekurasikirwa kwenguva refu. Kudzoka kwe raw material carbon 4 kunokonzerwa nekuchengetwa kwemidziyo ye alkylation ine mutengo wakaderera. Izvi zvinosanganisira mayuniti e alkylation pamwe nezvimwe. Zvichikanganiswa nerutivi rwemitemo inorambidza, mutengo we olefin carbon four waderera kusvika panzvimbo yakaderera, kwete mari ye alkylation device chete, asiwo dividend ye olefin isomerization device, mamwe emabhizinesi akamiswa akatangazve basa kana kuti akatangazve kuronga basa, uye divi rekudiwa rave nani zvishoma nezvishoma.

Musika we olefin carbon 4 hauna kudzokera kurunyararo nekuda kwekuenzana kutsva, uye kuongororwa nguva nenguva kuchakanganisawo mafambiro ari kuita zvinhu, uye olefin carbon 4 yeramangwana icharamba ichitsvaga budiriro itsva mukuvhiringidzika uku.
