Mu cyumweru gishize, isoko rya Metharal yo murugo yasubijwe muhungabana. Ku mugabane wa Mainland, mu cyumweru gishize, igiciro cy'amakara ku mpera cyahagaritse kugwa no kuzimya. Guhungabana no kuzamuka kwa methanol ejo hazaza hatanze isoko imbaraga nziza. Imiterere yinganda zateye imbere kandi ikirere rusange cyisoko ryasubiwemo. Mugihe cyicyumweru, abacuruzi no kumanura ibigo byaguzwe cyane, kandi kohereza hejuru byari byoroshye. Icyumweru gishize, ibarura ry'ibigo byo gukora byagabanutse cyane, kandi imitekerereze y'abakora yari ikomeye. Mu ntangiriro z'icyumweru, igiciro cyo kohereza cya metstream Methanol Abakora, hanyuma isoko rusange mu Mugabane wakomeje kuzamuka. Ku bijyanye n'ibyambu, gutangira mpuzamahanga biracyari kurwego rwo hasi. Mugutegereza kugabanuka kwijwi ryitumizi, itangwa ryabakoresha bashikamye. Cyane cyane kuri 23, amakara yatwaye methanol azaba hejuru, kandi ikiguzi cya post nacyo cyahagurukiye cyane. Ariko, inganda za Olefin yicyambu ni intege nke kandi igiciro kirazamuka vuba. Abashimushiri bategereza cyane cyane - kandi - Reba, hamwe nubucuruzi ni rusange.
Mugihe kizaza, igiciro cyamakara giteganijwe gukomera kubishyigikira. Kugeza ubu, isoko rya methanol riri mu bihe bikomeye. Ibigo bya methanol byafunze kubiciro birangiye mugihe cyambere byagaruwe buhoro buhoro cyangwa bifite gahunda yo kugarura mugihe cya vuba. Ariko, byatewe no kuzamuka kwa vuba kubiciro byamakara, zimwe mumigambi yumwimerere yo gutangira imitwe mu mpera zukwezi zasubitswe. Byongeye kandi, inganda nyamukuru muri gahunda yo mu majyaruguru y'uburengerazuba bwo gukora igenzura ry'impeshyi hagati ya Werurwe. Kuruhande ruto, hepfo downstream itangira ni sawa. Kugeza ubu, Olefin itangira ntabwo ari hejuru. Gahunda yakurikiyeho ya Ningbo Yamazaki na Zhongyuan Sorylene ya Ethylene igomba kwibanda ku gukira. Ku bijyanye n'ibyambu, ibarura ry'icyambu igihe gito rishobora kuguma hasi. Muri rusange, biteganijwe ko isoko ya methanol yo murugo izaba ihindagurika mugihe gito. Kwitondera bigomba kwishyurwa kugarura methanol na Downstream Olefin.
