Kuyobora】 Muri iki cyumweru, imikorere rusange yinganda za propylene yazamutseho gato. Uruhande rutanga ibicuruzwa rukomeje kuba rudasanzwe, mugihe igipimo cyuzuye cyibikorwa byibicuruzwa byo hasi byazamutse. Hamwe n’inyungu zongerewe inyungu z’ibicuruzwa bimwe na bimwe byo hasi, ibihingwa byo hasi byakira ibiciro bya propylene byiyongereye, bishimangira inkunga yo gukenera propylene no gutanga isoko runaka ku isoko rya propylene.
Muri iki cyumweru, ibiciro byisoko rya propylene byongeye kwiyongera nyuma yo gukubita hasi, hamwe nisoko ryo gutanga isoko nibisabwa nkibintu nyamukuru. Ikigereranyo cya buri cyumweru cya propylene muri Shandong kuri iki cyumweru cyari 5.738 yuan / toni, ukwezi-ukwezi kugabanuka 0.95%; impuzandengo ya buri cyumweru mu Bushinwa bwi Burasirazuba yari 5.855 yuan / toni, ukwezi-ukwezi kugabanuka 1.01%.
Muri iki cyumweru, ibiciro byurwego rwinganda byavanze nurwego ruhindagurika muri rusange. Ibiciro by'ibikoresho by'ibanze byerekanaga itandukaniro ryamanutse hamwe n’ibihindagurika bito muri rusange, bigira ingaruka nke kubiciro bya propylene. Impuzandengo ya propylene yagabanutseho ukwezi-ukwezi hanyuma iragaruka nyuma yo gukubita hasi. Ibiciro by'ibikomoka hasi nabyo byari bifite kuzamuka no kumanuka: muri byo, igiciro cya oxyde ya propylene cyazamutse cyane, mu gihe igiciro cya acide acrilike cyagabanutse ku buryo bugaragara. Ibihingwa byinshi byo hepfo byuzuza ububiko kubiciro buke.
Igipimo cyibikorwa byinganda bigarukira hamwe nibitangwa neza.
Muri iki cyumweru, igipimo cya propylene cyageze kuri 79.57%, cyiyongereyeho amanota 0,97 ku cyumweru gishize. Mu cyumweru, ibice bya PDH bya Haiwei na Juzhengyuan, ndetse n’ishami rya MTO rya Hengtong, byafashwe neza, byari bifite imbaraga nke mu gutanga isoko. Inganda za propylene zagumanye ibintu bidahwitse, kandi ibice bimwe na bimwe byahinduye imizigo yabyo, bituma izamuka ry’imikorere muri rusange muri iki cyumweru.
Hasi Kumurongo Wibikorwa Byuzuye Igipimo Cyizamuka, Icyifuzo cya Propylene kiratera imbere
Kuri iki cyumweru, igipimo rusange cy’ibikorwa by’inganda za propylene zimanuka zigeze kuri 66.31%, byiyongereyeho amanota 0.45 ku cyumweru gishize. Muri byo, ibipimo by'ifu ya PP na acrylonitrile byazamutse cyane, mu gihe ibya fenol-ketone na acide acrylic byagabanutse ku buryo bugaragara. Muri iki cyumweru, igipimo rusange cyibikorwa byo hasi byiyongereye, bituma icyifuzo cya propylene gikomoka ku bimera byo hasi. Byongeye kandi, hamwe nibiciro bya propylene kurwego rwo hasi hamwe ninyungu yibicuruzwa bimwe na bimwe byo hasi byateye imbere, ishyaka ryo kugura amasoko yo hepfo ya propylene ryarazamutse, ritanga imbaraga nkeya kubisabwa na propylene.
Inyungu yibicuruzwa byo hasi byongera buhoro buhoro, Kongera Kwemera Ibiciro bya Propylene
Muri iki cyumweru, inyungu yibicuruzwa bya propylene yamanutse byari bivanze. Hamwe nigiciro cya propylene kurwego rwo hasi ugereranije, igitutu cyibiciro byibicuruzwa bimwe na bimwe byoroheje. By'umwihariko, ifu ya PP yavuye mu nyungu ijya mu gihombo muri iki cyumweru, mu gihe inyungu ya PO (propylene oxyde) yariyongereye. Igihombo cya n-butanol cyagutse, mugihe icya 2-Ethylhexanol, acrylonitrile, na fenol-ketone yagabanutse. Byongeye kandi, inyungu ya acide acrylic na ECH ishingiye kuri propylene yagabanutse. Muri rusange, inyungu yibicuruzwa byo hasi byateye imbere gato ariko biringaniye, ibyo bikaba byongereye agaciro kubiciro bya propylene.
