Ngesonto eledlule, imakethe ye-methanol yasekhaya yaphinde yathuthukiswa ekushashweni. Emkhathini omkhulu, ngesonto eledlule, intengo yamalahle endaweni yokuphela yamisa ukuwa yaphenduka. Ukushaqeka nokukhuphuka kwesikhathi esizayo se-methanol kwanikeza imakethe ukukhuphula okuhle. Isimo somkhakha sathuthukiswa kanye nomoya ophelele wemakethe. Evikini, abathengisi namabhizinisi aphansi athengwe ngenkuthalo, futhi ukuthunyelwa kwe-Upstream kwabushelelezi. Ngesonto eledlule, ukusungulwa kwamabhizinisi okukhiqiza kwehle kakhulu, futhi ukucabanga kwabakhiqizi kwakuqinile. Ekuqaleni kwesonto, intengo yokuthumela yabakhiqizi be-upstream methanol yehlisiwe, bese imakethe ephelele ezweni laqhubeka nokuvuka. Ngokuya kwamachweba, ukuqala kwaphesheya kwawo kusezingeni eliphansi. Ngokulindela ukuncishiswa kwevolumu yokungenisa, ukunikezwa kwabasebenzisi be-Spot kuqinile. Ikakhulu ku-23, amalahle aqhume i-methanol ikusasa elizayo, futhi intengo yamabala amachweba nayo yavuka kakhulu. Kodwa-ke, imboni yePort Olefind ibuthakathaka kanti intengo ikhuphuka ngokushesha. Abangena ngaphakathi ikakhulukazi balinda-bese-ukubona, futhi umkhathi wokuhweba ujwayelekile.
Ngokuzayo, uhlangothi lwezindleko zamalahle kulindeleke ukuthi lube namandla ukuluxhasa. Njengamanje, imakethe ye-methanol isesimweni esifudumele. Amabhizinisi we-Methanol avale phansi ekugcineni kokuphakelwa phansi ekuqaleni kwesikhathi alulame kancane kancane noma abe nohlelo lokutakula esikhathini esizayo esiseduze. Kodwa-ke, okuthintwe ukukhuphuka kwamuva kumanani amalahle, ezinye zezinhlelo zokuqala zokuqalisa kabusha amayunithi ngasekupheleni kwenyanga kuhanjisiwe. Ngaphezu kwalokho, amafektri asemqoka ohlelweni olusenyakatho nentshonalanga yokwenza ukuhlolwa kwentwasahlobo maphakathi noMashi. Ngasohlangothini oluphansi, ukuqala kwendabuko phansi kulungile. Njengamanje, isiqalo se-OleFEF asiphezulu. Uhlelo olulandelayo lokuqalisa kabusha lwe-Ningbo Fude kanye neZhongyuan Ethylene Isitoreji kufanele sigxile ekubuyiselweni kwalo. Ngokuya kwamachweba, ukusungulwa kwechweba kwesikhashana kungahlala kuphansi. Ngokuvamile, kulindeleke ukuthi imakethe ye-methanol yasekhaya izoba namandla kakhudlwana esikhathini esifushane. Ukunakwa kufanele kukhokhwe ekubuyiselweni kwe-methanol nama-Downstream Olefith amabhizinisi.
