Mu cyumweru cya mbere Ugushyingo, Zhenhai Phase II na Tiajin Bohai Imiti, Ltd. yakoraga nabi kubera igiciro cya Styrene, igitonyanga cyorezo mu bwato, intara ya Shandong, muri Guhagarika Huatai kubungabunga, kandi itangira rya promeylene yo murugo yagabanutseho 70%. Ariko, gutangira bike ntabwo byahagaritse inzira yo hepfo ya propayle. Iyo igiciro cya propaylene okiside yagabanutseho 8700 ya Touan / toni, igiciro cya chlorine yamashanyarazi yazamutse, iterwa nimbaraga zamashanyarazi, Shacue yagabanije umutwaro wibice byacyo. Mu mbogamizi y'igiciro cya propay oxide inzira nyinshi, ihohoterwa rirenze ryakomeje kuba ryiza, kandi imitekerereze yo gukosora ibiciro yazamutse. Downstream ntabwo ifite ibyago cyane kugirango utegereze kugabanuka kwumurongo wa propaylene. Kwiyongera gukurikizwa no kugura. Imitwe imwe nayo ikubiyemo no gutanga ibitekerezo buri gihe. Ikirere cy'isoko cyateye imbere, kandi igiciro cya propaylene oxide yahagaritse kugwa no kongera kugwa.
Mu cyumweru cya kabiri, hamwe no kugarura umutwaro wa Sanue, urangiye Huatai, kandi iherezo rya Guanegra ya Guangra woung, umutwaro wa junling wasubiye buhoro, uruganda rwama ogisi yo mu rugo rwatangiye kugaruka kuri 73%. Terminal yasubiye gutegereza no kureba nyuma yo kuzuzuza gusa igice cyakurikiyeho nyuma yicyumweru cya mbere. Nta gutegereza kuzungura muri iki cyumweru, isoko ryabaye nke cyane ku nkunga y'ibyiza, ariko ibikoresho fatizo byashize kandi ibyatsi bya prolorine byari bimaze kuzamuka, kandi ibyatsi bya porolorine byari bimaze kuzamuka, kandi ibyatsi bya proplone byari mu gihirahiro cyo kuzamuka no kugwa, hamwe n'inzitizi mbisi Ibikoresho, igiciro cya Chlorohydrin cyahatiwe kuzamuka ka Yuan 100, kandi ikirere cyisoko cyakomeje kubanganiye. Icyumweru kirangiye, amakuru ya Shandong Ibimera binini byatangaga amaso ya propaylene yambutse ku isoko, kandi imitekerereze ku isoko yazamuwe. Shandong Shida Shenghua igihingwa cyaparitse Shandong Bluastar iburasirazuba yatangiye, kandi yaguzwe mubisanzwe. Uruganda rwa proppide ya proppide yakomeje ibirori byorohereza byoroshye. Ku cyumweru cya kabiri, Shandong yagereranyaga ibarura rito ry'igihingwa, kandi isoko rirahaguruka riri mu buryo bwo kwanga kugurisha.
Mu cyumweru cya gatatu, isoko ryatangiye hejuru gato mumajyaruguru. Kugeza ubu, hari ubutumwa bwinshi bwubusa muriIsoko rya Spapylene. Ibyiza ni: Shandong Huan C igihingwa, iyobowe nikibazo cyorezo, yagabanije imitwaro yibice byayo; Sinochem Quanzhou ifite gahunda yo kugabanya imitwaro, kandi ahantu hatanga isoko ni bike; Biteganijwe ko Shandong Dachang azakomeza gukuramo imyanda; Kugabanya umusaruro wurubuga rwa Marine Scill. Ibyinshi mu ngingo mbi ninits nshya: Igice cya Provijes cya tegda cya Tengda giteganijwe gutanga ibikoresho, kandi inzira yihariye iracyakeneye kwitabwaho; Hano hari gahunda yo kugaburira buri kwezi yo gutanga igikoresho cya Yida; Kugeza ubu, ibitero bya spolorine na proplene birimo gukora intege nke kandi biragoye gutera inkunga mugihe gito; Bigira ingaruka kuri shampiyona nibibazo byinganda zinganda, ibikorwa bya terminal burigihe biri hasi. Mugihe gito, biteganijwe ko isoko rya ecpeylene rizakora gukomera gato munsi yinkunga itangwa neza. Mugihe kizaza, niba ikiguzi gikomeje kugorana gutera inkunga, imyanda ya propylene izakomeza gutegereza kugaba igitutu. Gushyigikirwa nigiciro cyibikorwa bishya, umwanya wo kugabanuka ni muto. Mugihe kizaza, biteganijwe ko umurimburo wa propylene uzakomeza kunyeganyega gato, hamwe n'umwanya muto hejuru no hepfo.
