Ethylene (C2H4)

Magadzirirwo ehunyanzvi

Mumamiriro ezvinhu akajairwa, ethylene igesi risina ruvara, rinonhuwa zvishoma rinobvira moto rine density ye1.178g/L, iyo isina kukora zvakanyanya kupfuura mhepo. Hainyungudike mumvura, hainyungudike zvakanyanya muethanol, uye inonyungudika zvishoma muethanol, ketones, uye benzene. , Inonyungudika mu ether, inonyungudika nyore nyore mu organic solvents dzakadai se carbon tetrachloride.Ethylenendeimwe yezvigadzirwa zvemakemikari zvine huwandu hwakakura hwezvinhu zvinoburitswa pasi rose. Indasitiri ye ethylene ndiyo musimboti weindasitiri ye petrochemical.EthyleneZvigadzirwa zvinodarika 75% yezvigadzirwa zve petrochemical uye zvine chinzvimbo chakakosha muhupfumi hwenyika. Pasi rose rakaona kugadzirwa kwe ethylene sechimwe chezviratidzo zvakakosha zvekuyera nhanho yekukura kweindasitiri ye petrochemical yenyika. Ethylene chinhu chakakosha chemakemikari e organic, chinoshandiswa zvakanyanya mukugadzira polyethylene, ethylene propylene rabha, polyvinyl chloride, nezvimwewo. Ethylene chimwe chezvinhu zvakakosha zve petrochemical industry. Panyaya yezvinhu zvakagadzirwa, inoshandiswa zvakanyanya mukugadzira polyethylene, vinyl chloride, nezvimwewo; panyaya ye organic synthesis, inoshandiswa zvakanyanya mukugadzira ethanol, ethylene oxide, ethylene glycol, acetaldehyde, uye propylene. Mhando dzakasiyana dzezvinhu zvekutanga zve organic synthesis zvakaita se aldehydes nezvimwe zvinobva mazviri; kuburikidza ne halogenation, inogona kugadzira chloroethylene, chloroethane, bromoethane, nezvimwewo. Ethylene inonyanya kushandiswa segasi rakajairika rezvishandiso zvekuongorora mumakambani e petrochemical; inoshandiswa segasi rinobvisa zvipembenene kubva mumiti yakaita semaranjisi emudumbu, matangerines, mabhanana, nezvimwewo; inoshandiswa mukugadzira mishonga nezvinhu zvemhando yepamusoro; inoshandiswa mukugadzira magirazi akakosha eindasitiri yemotokari; inoshandiswa semuchina wekuisa mufiriji, Kunyanya muzvifekitori zveLNG liquefaction. Nzira dzekuchengetedza: Chengeta mudura rinotonhorera, rine mhepo inofema. Chengeta kure nemoto nekupisa. Tembiricha yekuchengetera haifanirwe kudarika 30°C. Inofanira kuchengetwa yakasiyana ne oxidants nema halogens, uye dzivisa kuchengetwa kwakasiyana. Shandisa mwenje usingaputike uye nzvimbo dzekufema. Hazvibvumirwi kushandisa michina nemidziyo inogona kudonha nemoto. Nzvimbo yekuchengetera inofanira kunge yakashongedzwa nemidziyo yekurapa inobuda nekukurumidzira.

Kushandiswa:

①Makemikari:

Pakati nepakati muindasitiri yemakemikari uye kugadzirwa kwepurasitiki

②Chinwiwa Chekudya:

Kuibva kwemichero, kunyanya mabhanana..

Girazi:

Magirazi emhando yepamusoro eindasitiri yemotokari (girazi remotokari).

④ Kugadzira:

Kucheka simbi, kupinza simbi uye kupfapfaidza nekupisa kwakanyanya.

⑤Chinotonhorera:

Chinotonhorera mufiriji kunyanya mumafekitori eLNG liquefaction.

⑥Rabha Plastiki:

Inoshandiswa mukubvisa rabha.

Pakeji yakajairika:

Zvakanakira:

①Kuchena kwakanyanya, nzvimbo itsva;

②Mugadziri wezvitupa zveISO;

③Kutumira nekukurumidza;

④Sisitimu yekuongorora yepamhepo yekudzora mhando padanho rega rega;

⑤Kushandiswa kwakawanda uye kwakanyatsorongwa kwekubata silinda usati wazadza;
