Mu cyumweru gishize, isoko ry’ibicuruzwa by’imiti mu gihugu byakomeje guhura n’amanuka, aho igabanuka rusange ryagutse ugereranije n’icyumweru gishize.Isesengura ryisoko ryisoko ryibice bimwe
1. Methanol
Icyumweru gishize, isoko rya methanol ryihutishije inzira yo kumanuka.Kuva mu cyumweru gishize, isoko ry’amakara ryakomeje kugabanuka, inkunga y’ibiciro irasenyuka, kandi isoko rya methanol rirahangayitse kandi igabanuka ryiyongereye.Byongeye kandi, kongera gutangira ibikoresho byo kubungabunga hakiri kare byatumye ubwiyongere butangwa, biganisha ku myumvire ikomeye ku isoko no kongera isoko ridindira.Nubwo hari isoko rikenewe ryuzuzwa ku isoko nyuma yiminsi itari mike igabanutse, muri rusange isoko ryagumye ridakomeye, cyane cyane ko amasoko yo hepfo yinjira mugihe cyigihe kitari gito, bikagorana kugabanya ikibazo cya methanol idahwitse.
Ku gicamunsi cyo ku ya 26 Gicurasi, igipimo cy’ibiciro bya methanol mu Bushinwa bw’Amajyepfo cyari gifunze kuri 933.66, kigabanuka 7.61% guhera ku wa gatanu ushize (19 Gicurasi).
2. Soda ya Caustic
Icyumweru gishize, isoko yimbere ya alkali isoko yabanje kuzamuka hanyuma iragwa.Mu ntangiriro zicyumweru, byatewe no gufata neza ibihingwa bya chlor alkali mu majyaruguru n’Uburasirazuba bw’Ubushinwa, icyifuzo cy’imigabane mu mpera z’ukwezi, hamwe n’igiciro gito cya chlorine y’amazi, imitekerereze y’isoko yarateye imbere, n’isoko rusange rya amazi ya alkali yagarutse;Ariko, ibihe byiza ntibyigeze bimara igihe kinini, kandi nta terambere ryigeze rihinduka mubisabwa hasi.Muri rusange icyerekezo cyisoko cyari gito kandi isoko ryaragabanutse.
Icyumweru gishize, isoko ya flake alkali yo mu gihugu yariyongereye cyane.Bitewe no kugabanuka kw'igiciro cyisoko mugihe cyambere, igiciro gito gikomeje cyashishikarije bamwe mubakinnyi bo hasi basaba kuzuzwa, kandi ibyoherezwa mu ruganda byateye imbere, bityo bizamura isoko rya flake caustic soda.Ariko, hamwe n’izamuka ry’ibiciro by’isoko, isoko ryongeye gukumirwa, kandi isoko rusange rikomeje kuzamuka cyane.
Kugeza ku ya 26 Gicurasi, igipimo cy’ibiciro bya soda ya Caustic y’Ubushinwa cyafunzwe 1175
Amanota 02, amanutse 0,09% guhera kuwa gatanu ushize (19 Gicurasi).
3. Ethylene glycol
Icyumweru gishize, igabanuka ryisoko rya Ethylene glycol ryihuta.Hamwe n'ubwiyongere bw'igipimo cy'isoko rya Ethylene glycol no kwiyongera kw'ibarura ry'ibyambu, isoko rusange ryiyongereye ku buryo bugaragara, kandi imyifatire yo kwanga isoko yarakomeje.Byongeye kandi, imikorere idahwitse y’ibicuruzwa mu cyumweru gishize nayo yatumye kwiyongera k'umuvuduko wo kugabanuka ku isoko rya Ethylene glycol.
Kugeza ku ya 26 Gicurasi, igipimo cy’ibiciro bya Ethylene glycol mu Bushinwa bw’Amajyepfo cyafunze amanota 685.71, kigabanukaho 3,45% ugereranije n’uwagatanu ushize (19 Gicurasi).
4. Styrene
Icyumweru gishize, isoko rya styrene yo mu gihugu ryakomeje kugabanuka.Mu ntangiriro z'icyumweru, nubwo peteroli mpuzamahanga ya peteroli yongeye kwiyongera, ku isoko nyirizina habaye imyumvire ikomeye yo kwiheba, kandi isoko rya styrene ryakomeje kugabanuka kubera igitutu.By'umwihariko, isoko rifite imitekerereze ikabije ku isoko ry’imiti yo mu gihugu, ibyo bikaba byaratumye umuvuduko w’ubwikorezi wiyongera ku isoko rya styrene, kandi isoko rusange naryo ryakomeje kugabanuka.
Kugeza ku ya 26 Gicurasi, igipimo cy’ibiciro bya styrene mu Bushinwa bw’Epfo cyafunze ku manota 893.67, igabanuka rya 2.08% ugereranije no ku wa gatanu ushize (19 Gicurasi).

Isesengura rya nyuma
Nubwo muri iki cyumweru ibarura ry’Amerika ryagabanutse cyane, kubera icyifuzo gikomeye muri Amerika mu mpeshyi, ndetse no kugabanya umusaruro wa OPEC + na byo byazanye inyungu, ikibazo cy’imyenda muri Amerika ntikirakemuka.Byongeye kandi, ibyifuzo by’ubukungu bw’uburayi n’Amerika biracyahari, bishobora kugira ingaruka mbi ku isoko ry’amavuta mpuzamahanga ya peteroli.Biteganijwe ko hazakomeza kubaho igitutu cyo kumanuka ku isoko mpuzamahanga rya peteroli.Urebye imbere mu gihugu, isoko mpuzamahanga rya peteroli ya peteroli rifite umuvuduko udasanzwe wo kuzamuka, inkunga ntarengwa, kandi isoko ry’imiti mu gihugu rishobora gukomeza kuba intege nke kandi rihindagurika.Byongeye kandi, bimwe mu bicuruzwa biva mu mahanga byinjira mu gihe cyizuba, kandi ibikenerwa mu miti biracyafite intege nke.Kubwibyo, biteganijwe ko umwanya wongeye kugaruka kumasoko yimiti yo murugo ari muto.
1. Methanol
Vuba aha, abakora ibicuruzwa nka Sinayi Xinye bateganya kubungabunga, ariko ibice byinshi byo mu Bushinwa National Offshore Chemical Corporation, Shaanxi, na Mongoliya yo mu gihugu imbere birateganya gutangira, bikavamo amasoko ahagije aturuka ku mugabane w’Ubushinwa, ibyo bikaba bitajyanye n’isoko rya methanol .Kubijyanye nibisabwa, ishyaka ryibice nyamukuru bya olefin byo gutangira kubaka ntabwo biri hejuru kandi bikomeza guhagarara neza.Byongeye kandi, ibyifuzo bya MTBE, formaldehyde, nibindi bicuruzwa byiyongereyeho gato, ariko muri rusange iterambere ryibisabwa riratinda.Muri rusange, biteganijwe ko isoko rya methanol rizakomeza kuba intege nke kandi rihindagurika nubwo bitangwa bihagije nibisabwa gukurikiranwa.
2. Soda ya Caustic
Kubijyanye na alkali yamazi, hari umuvuduko wo kuzamuka kumasoko yimbere ya alkali.Bitewe n'ingaruka nziza zo kubungabunga ibicuruzwa bimwe na bimwe byo mukarere ka Jiangsu, isoko ya alkali yamazi yerekanye umuvuduko wo hejuru.Nyamara, abakinyi bo hasi bafite ubushake buke bwo kwakira ibicuruzwa, bishobora kugabanya inkunga yabo kumasoko ya alkali yamazi kandi bikagabanya izamuka ryibiciro rusange byisoko.
Kubijyanye na flake alkali, isoko ya flake alkali yo murugo yagabanije umuvuduko wo hejuru.Bamwe mu bakora inganda baracyerekana ibimenyetso byo kuzamura ibiciro byabo byoherezwa, ariko ibintu byubucuruzi birashobora kugabanywa nisoko rusange ryizamuka ryiterambere.Kubwibyo, ni izihe mbogamizi ku miterere yisoko.
3. Ethylene glycol
Biteganijwe ko intege nke zisoko rya Ethylene glycol zizakomeza.Kuzamuka kw'isoko mpuzamahanga rya peteroli ni bike, kandi inkunga y'ibiciro ni mike.Kuruhande rwibitangwa, hamwe nogutangira ibikoresho byo kubungabunga hakiri kare, harateganijwe ko izamuka ryamasoko ryiyongera, ibyo bikaba byerekana ko isoko rya Ethylene glycol ryifashe.Kubijyanye nibisabwa, umusaruro wa polyester uratera imbere, ariko umuvuduko witerambere uratinda kandi isoko rusange ntirigira imbaraga.
4. Styrene
Umwanya uteganijwe kuzamuka kumasoko ya styrene ni ntarengwa.Isoko mpuzamahanga rya peteroli ya peteroli iracyafite intege nke, mugihe imbere mu gihugu imbere ya benzene nziza na styrene bifite intege nke, hamwe n’inkunga idahwitse.Nyamara, hari impinduka nke mubitangwa muri rusange nibisabwa, kandi isoko rya styrene rishobora gukomeza guhura nihindagurika rito.
