【Inkokheli】Kule veki, indlela yokusebenza iyonke yecandelo le-propylene industry iphucuke kancinci. Icala lokubonelela lihlala likhululekile ngokubanzi, ngelixa isalathisi esibanzi sezinga lokusebenza kweemveliso ezisezantsi sinyukile. Kunye nemida yenzuzo ephuculweyo yezinye iimveliso ezisezantsi, ukwamkelwa kwamaxabiso e-propylene kwezityalo ezisezantsi kunyukile, okuqinisa inkxaso yemfuno ye-propylene kunye nokubonelela ngokunyuka okuthile kwimarike ye-propylene.
Kule veki, amaxabiso emarike yepropylene yasekhaya abuyele esiphelweni emva kokufika ezantsi, apho ukunikezelwa kwemveliso kunye nomdlalo wemfuno kuphawu oluphambili. Ixabiso eliqhelekileyo lepropylene ngeveki eShandong kule veki yayiyi-5,738 yuan/ton, ukwehla kwenyanga ngenyanga kwe-0.95%; ixabiso eliqhelekileyo leveki eMpuma China yayiyi-5,855 yuan/ton, ukwehla kwenyanga ngenyanga kwe-1.01%.
Kule veki, iindlela zamaxabiso zecandelo lezemizi-mveliso zixutywe noluhlu olulinganiselweyo lokuguquguquka ngokubanzi. Amaxabiso ezinto eziphambili ezisetyenzisiweyo abonise ukunyuka nokwehla okwahlukileyo kunye nokuguquguquka okuncinci ngokubanzi, okunempembelelo encinci kwiindleko zepropylene. Ixabiso eliqhelekileyo lepropylene lehle kancinci inyanga nenyanga kwaye laphinda labuya emva kokufika ezantsi. Amaxabiso ezinto eziphumayo ngezantsi nawo abe nokunyuka nokwehla: phakathi kwazo, ixabiso lepropylene oxide lenyuke kakhulu, ngelixa ixabiso le-acrylic acid lehla kakhulu. Uninzi lwezityalo ezisezantsi zizalise amasheya ngamaxabiso aphantsi.
Izinga lokusebenza kweshishini liyancipha ngenxa yokunikezelwa kweenkonzo okungekho semthethweni.
Kule veki, izinga lokusebenza kwepropylene lifikelele kwi-79.57%, ukunyuka kweepesenti ezingama-0.97 ukusuka kwiveki ephelileyo. Phakathi evekini, iiyunithi zePDH zaseHaiwei naseJuzhengyuan, kunye neyunithi yeMTO yaseHengtong, ziye zalungiswa, nto leyo ebenokunyuka okuncinci kwimarike. Ishishini lepropylene ligcine imeko yokubonelela ngombane okhululekileyo, kwaye ezinye iiyunithi zilungise imithwalo yazo yokusebenza, nto leyo ekhokelele ekunyukeni okuncinci kwinqanaba lokusebenza kweshishini kule veki.
I-Downstream Comprehensive Operating Rate Index iyakhula, imfuno yepropylene iyaphucuka
Kule veki, isalathisi esipheleleyo sezinga lokusebenza kwemizi-mveliso yepropylene esezantsi komsinga simi kwi-66.31%, ukunyuka kweepesenti ezingama-0.45 ukusuka kwiveki ephelileyo. Phakathi kwazo, amazinga okusebenza e-PP powder kunye ne-acrylonitrile anyuke kakhulu, ngelixa lawo e-phenol-ketone kunye ne-acrylic acid ehle kakhulu. Kule veki, isalathisi sezinga lokusebenza ngokubanzi sinyukile, nto leyo eqhubela phambili imfuno eqinileyo yepropylene evela kwizityalo ezisezantsi komsinga. Ukongeza, ngamaxabiso epropylene aphantsi kunye nemida yenzuzo yezinye iimveliso ezisezantsi komsinga iphucuka, umdla wokuthengwa kwepropylene esezantsi komsinga unyukile, nto leyo enika ukunyuka okuncinci kwimfuno yepropylene.
Inzuzo yeemveliso ezisezantsi iphucula kancinci, iphucula ukwamkelwa kwamaxabiso epropylene
Kule veki, inzuzo yeemveliso zepropylene ezisezantsi ixubene. Njengoko iziko lexabiso lepropylene likwinqanaba eliphantsi, uxinzelelo lweendleko zezinye iimveliso ezisezantsi luye lwehla. Ngokukodwa, umgubo wePP utshintshe ukusuka kwinzuzo ukuya ekulahlekelweni kule veki, ngelixa inzuzo ye-PO (propylene oxide) inyukile. Umda wokulahleka kwe-n-butanol wanda, ngelixa owe-2-ethylhexanol, i-acrylonitrile, kunye ne-phenol-ketone unciphile. Ukongeza, inzuzo ye-acrylic acid kunye ne-propylene-based ECH yehlile. Ngokubanzi, inzuzo yeemveliso ezisezantsi iphucuke kancinci kodwa ngokuphakathi, nto leyo ephucule ukwamkelwa kwazo kwamaxabiso epropylene.
