Thepa ea Ethylene MMA le eona e na le mefokolo.Ntlha ea pele, ho hlokahala lisebelisoa tse tšehetsang limela tsa ethylene, moo ethylene e hlahisoang haholo ke limela tse kopantsoeng, kahoo ho tšehetsa nts'etsopele ea likhoebo tse kopanetsoeng hoa hlokahala.Haeba ethylene e rekoa, moruo o fokola.Ea bobeli, ho na le lihlopha tse peli feela tsa lisebelisoa tsa ethylene MMA lefatšeng.Merero ea China e ntseng e hahuoa e sebelisa theknoloji ea Setsi sa Mahlale sa China, 'me likhoebo tse ling li ke ke tsa fumana theknoloji habonolo le ka nepo.Ntlha ea boraro, lisebelisoa tsa MMA tsa ts'ebetso ea ethylene li na le nako e telele ea ho phalla, tekanyo e kholo ea lichelete, palo e kholo ea chlorine e nang le metsi a litšila e tla hlahisoa ts'ebetsong ea tlhahiso, 'me litšenyehelo tsa phekolo ea litšila tse tharo li phahame.
Ea bobeli, tlhōlisano ea litšenyehelo ea yuniti ea MMA haholo-holo e tsoa ho ethylene e tšehetsang, ha ethylene e ka ntle e se na molemo o hlakileng oa tlhōlisano.Ho latela lipatlisiso, yuniti ea MMA ea mokhoa oa ethylene ke lithane tse 0.4294 tsa ethylene, lithane tse 0.387 tsa methanol, 661.35 Nm ³ Khase ea Synthetic, lithane tse 1.0578 tsa chlorine e tala li hlahisoa ke karabelo e kopaneng, 'me ha ho na sehlahisoa sa methacrylic acid molemong oa tlhahiso. .
Ho latela lintlha tse amehang tse lokollotsoeng ke Shanghai Yunsheng Chemical Technology Co., Ltd., theko ea MMA ea mokhoa oa ethylene e ka ba 12000 yuan/ton ha ethylene e le 8100 yuan/ton, methanol ke 2140 yuan/ton, khase ea maiketsetso ke 1.95 yuan/ cubic meter, le chlorine e tala ke 600 yuan/ton.Ha ho bapisoa le nako e tšoanang, litšenyehelo tsa molao tsa mokhoa oa C4 le mokhoa oa ACH li phahame.Ka hona, ho ea ka maemo a hona joale a 'maraka, MMA ea ethylene ha e na tlhōlisano e hlakileng ea moruo.
Leha ho le joalo, tlhahiso ea MMA ka mokhoa oa ethylene e ka 'na ea lumellana le lisebelisoa tsa ethylene.Ethylene ha e le hantle e tsoa ho naphtha cracking, mashala synthesis, joalo-joalo Tabeng ena, tlhōlisano ea tlhahiso ea MMA ka mokhoa oa ethylene e tla ameha haholo-holo ka theko ea thepa e tala ea ethylene.Haeba thepa e tala ea ethylene e itlhahisa, e tlameha ho baloa ho latela theko ea theko ea ethylene, e tla ntlafatsa haholo tlholisano ea litšenyehelo tsa ethylene MMA.
