Na Julaị 1, 2022, emume mmalite nke akụkụ mbụ nke ton 300,000.methyl methacrylate(nke a na-akpọ methyl methacrylate) MMA oru ngo nke Henan Zhongkepu Raw na New Materials Co., Ltd. bụ nke e mere na Puyang Economic and Technological Development Mpaghara, na-akara ngwa nke mbụ ọhụrụ set nke ionic mmiri mmiri catalytic ethylene MMA technology n'adabereghị nke mepụtara site na n'onwe ya. CAS na Zhongyuan Dahua.Nke a bụkwa osisi ethylene MMA izizi e bipụtara na China.Ọ bụrụ na etinyere ngwá ọrụ ahụ nke ọma, ọ ga-enweta ọganihu na mmepụta ethylene MMA nke China, nke nwere mmetụta dị oke mkpa na ụlọ ọrụ MMA.
Enwere ike ịkpọsa ngalaba MMA nke abụọ nke usoro ethylene na China na Shandong.A na-atụ anya na mbụ a ga-etinye ya na mmepụta gburugburu 2024, ma ọ nọ ugbu a na ọkwa nkwado mbụ.Ọ bụrụ na unit ahụ bụ eziokwu, ọ ga-abụ MMA nke abụọ nke usoro ethylene na China, nke dị oke mkpa maka nhazi nke usoro mmepụta MMA na China na mmepe nke ụlọ ọrụ kemịkalụ China.
Dị ka data dị mkpa si dị, e nwere usoro mmepụta MMA ndị a na China: usoro C4, usoro ACH, usoro ACH ka mma, BASF ethylene usoro na Lucite ethylene usoro.N'ụwa niile, usoro mmepụta ndị a nwere nrụnye ụlọ ọrụ.Na China, iwu C4 na iwu ACH emebela ụlọ ọrụ, ebe iwu ethylene emebeghị nke ọma.
Kedu ihe kpatara ụlọ ọrụ kemịkalụ China ji na-agbasa osisi ethylene MMA ya?Ọnụ ahịa mmepụta nke MMA nke usoro ethylene mepụtara ọ na-asọmpi?
Nke mbụ, osisi ethylene MMA emeela oghere na China ma nwee ọkwa teknụzụ mmepụta dị elu.Dị ka nnyocha e mere, e nwere nanị abụọ set nke ethylene MMA nkeji n'ụwa, nke dị na Europe na North America n'otu n'otu.Ọnọdụ teknụzụ nke nkeji ethylene MMA dị mfe.Ọnụego ojiji atomic karịrị 64%, na mkpụrụ dị elu karịa ụdị usoro ndị ọzọ.BASF na Lucite emeela nyocha teknụzụ na mmepe nke akụrụngwa MMA maka usoro ethylene n'oge, wee nweta mmepụta ihe.
Ngalaba MMA nke usoro ethylene anaghị esonye na akụrụngwa acidic, nke na-edugakwa na nrụrụ dị ala nke akụrụngwa, usoro mmepụta enyi na gburugburu ebe obibi, yana ogologo oge ọrụ na okirikiri.N'okwu a, ọnụ ahịa mbelata nke MMA unit na usoro ethylene n'oge arụ ọrụ dị ala karịa nke usoro ndị ọzọ.
Ngwa Ethylene MMA nwekwara ọghọm.Nke mbụ, a na-achọ ụlọ ọrụ nkwado maka osisi ethylene, nke a na-emepụtakarị ethylene site na osisi jikọtara ọnụ, ya mere a chọrọ nkwado mmepe nke ụlọ ọrụ agbakwunyere.Ọ bụrụ na a zụrụ ethylene, akụ na ụba adịghị mma.Nke abụọ, enwere naanị ihe abụọ ethylene MMA n'ụwa.Ọrụ China a na-ewu na-eji teknụzụ nke ụlọ akwụkwọ sayensị China, ụlọ ọrụ ndị ọzọ enweghị ike nweta teknụzụ n'ụzọ dị mfe na nke ọma.Nke atọ, ngwá ọrụ MMA nke usoro ethylene nwere usoro nhazi ogologo oge, nnukwu ego ntinye ego, nnukwu ego nke chlorine nwere mmiri mkpofu ga-emepụta na usoro mmepụta ihe, na ọgwụgwọ ọgwụgwọ nke mkpofu atọ ahụ dị elu.
Nke abụọ, ọnụ ahịa asọmpi nke ngalaba MMA na-esite na ethylene na-akwado, ebe ethylene mpụga enweghị uru asọmpi doro anya.Dị ka nyocha ahụ si kwuo, MMA unit nke ethylene usoro bụ 0.4294 tọn ethylene, 0,387 tọn methanol, 661.35 Nm ³ sịntetik gas, 1.0578 tọn chlorine crude na-emepụta site na mmeghachi omume, na enweghị methacrylic acid ngwaahịa na mmepụta usoro. .
Dị ka mkpa data wepụtara site Shanghai Yunsheng Chemical Technology Co., Ltd., na MMA na-eri nke ethylene usoro bụ banyere 12000 yuan / ton mgbe ethylene bụ 8100 yuan / ton, methanol bụ 2140 yuan / ton, sịntetik gas bụ 1.95 yuan / cubic mita, na chlorine crude bụ 600 yuan/ton.E jiri ya tụnyere otu oge ahụ, ụgwọ iwu nke usoro C4 na usoro ACH dị elu.Ya mere, dị ka ọnọdụ ahịa dị ugbu a si dị, ethylene MMA enweghị asọmpi akụ na ụba doro anya.
Agbanyeghị, mmepụta nke MMA site na usoro ethylene nwere ike dabara na akụrụngwa ethylene.Ethylene bụ isi sitere na naphtha cracking, coal synthesis, etc. N'okwu a, asọmpi nke mmepụta MMA site na usoro ethylene ga-emetụta ya site na ọnụ ahịa akụrụngwa ethylene.Ọ bụrụ na ethylene akụrụngwa na-enye onwe ya, a ga-agbakọ ya dabere na ọnụ ahịa ethylene, nke ga-eme ka asọmpi ethylene MMA dịkwuo mma.
Nke atọ, ethylene MMA na-eri ọtụtụ chlorine, ọnụahịa na nkwado mmekọrịta nke chlorine ga-ekpebikwa isi ihe na-akpata asọmpi ethylene MMA.Dị ka usoro mmepụta nke BASF na Lucite si dị, usoro abụọ a kwesịrị iri nnukwu chlorine.Ọ bụrụ na chlorine nwere mmekọrịta nkwado nke ya, ọ dịghị mkpa ka a tụlee ọnụ ahịa chlorine, nke ga-eme ka asọmpi ethylene MMA dịkwuo elu.
Ka ọ dị ugbu a, ethylene MMA adọtala ụfọdụ nlebara anya karịsịa n'ihi asọmpi nke ọnụ ahịa mmepụta yana ebe ọrụ dị nro nke otu ahụ.Na mgbakwunye, ihe ndị a chọrọ maka ịkwado akụrụngwa na-agbasokwa ụdị mmepe nke ụlọ ọrụ kemịkalụ China ugbu a.Ọ bụrụ na ụlọ ọrụ ahụ na-akwado ethylene, chlorine na gas synthesis, mgbe ahụ ethylene MMA nwere ike ịbụ ụdị mmepụta MMA kachasị ọnụ ahịa ugbu a.Ka ọ dị ugbu a, ụdị mmepe nke ụlọ ọrụ kemịkalụ China bụ ụlọ ọrụ nkwado zuru oke.N'okpuru omume a, usoro ethylene dabara na ethylene MMA nwere ike bụrụ ihe a na-elekwasị anya na ụlọ ọrụ ahụ.
