Icyumweru gishize, isoko rya methanol yo mu gihugu ryongeye kugaruka kubera ihungabana.Ku mugabane w'isi, icyumweru gishize, igiciro cy'amakara ku giciro cyarangiye cyahagaritse kugabanuka.Guhungabana no kuzamuka kwa methanol ejo hazaza byatumye isoko itera imbere.Umwuka winganda wateye imbere kandi ikirere rusange cyisoko cyongeye kwiyongera.Mugihe cyicyumweru, abacuruzi ninganda zo hasi baraguze bashishikaye, kandi ibyoherezwa hejuru byari byiza.Icyumweru gishize, ibarura ry’inganda zikora ryaragabanutse cyane, kandi imitekerereze yabakora yari ikomeye.Mu ntangiriro z'icyumweru, igiciro cyo kohereza ibicuruzwa byo mu bwoko bwa methanol yo hejuru cyaragabanutse, hanyuma isoko rusange ku mugabane w'isi rikomeza kuzamuka.Ku bijyanye n'ibyambu, gutangira mpuzamahanga biracyari ku rwego rwo hasi.Mugutegereza kugabanuka kwamafaranga yatumijwe hanze, itangwa ryabakoresha ibibanza rirakomeye.By'umwihariko ku ya 23, amakara yatumaga methanol ahazaza, kandi igiciro cy’ibyambu nacyo cyazamutse cyane.Nyamara, icyambu cya olefin inganda gifite intege nke kandi igiciro kizamuka vuba.Imbere ni ugutegereza-no-kubona, kandi ikirere cyo gucuruza ni rusange.
Mu bihe biri imbere, ibiciro byamakara biteganijwe ko bizakomera kugirango bishyigikire.Kugeza ubu, isoko rya methanol rimeze neza.Uruganda rwa Methanol rwahagaritse gutanga isoko mugihe cyambere rwakize buhoro buhoro cyangwa rufite gahunda yo gukira mugihe cya vuba.Icyakora, kubera izamuka ry’ibiciro by’amakara biherutse, zimwe muri gahunda zambere zo kongera gutangiza ibice mu mpera zukwezi zarasubitswe.Byongeye kandi, inganda nkuru zo mu majyaruguru yuburengerazuba zirateganya gukora igenzura ryimpeshyi hagati ya Werurwe.Kuruhande rwo hepfo, gakondo kumanuka gutangira ni byiza.Kuri ubu, olefin itangira ntabwo iri hejuru.Gahunda ikurikira yo gutangira ya Ningbo Fude na Zhongyuan Ethylene Ububiko igomba kwibanda ku kugarura kwayo.Kubireba ibyambu, ibarura ryigihe gito rishobora kuguma hasi.Muri rusange, biteganijwe ko isoko rya methanol yo mu gihugu rizahinduka cyane mugihe gito.Hagomba kwitonderwa kugarura methanol na olefin yo hepfo.
