Ngokwezibalo, kwikota yokuqala ka-2024, kongezwe iitoni ezingama-350000 zamandla amatsha emveliso, kwaye amashishini amabini emveliso, iGuangdong Petrochemical Second Line kunye neHuizhou Lituo, aqaliswa ukusebenza; Kunyaka olandelayo, iZhongjing Petrochemical iya kwandisa amandla ayo ngeetoni ezili-150000 ngonyaka * 2, kwaye okwangoku, amandla emveliso iyonke ye-polypropylene eTshayina yi-40.29 yezigidi zeetoni. Ngokwembono yengingqi, izixhobo ezisandula kongezwa zikwimimandla esemazantsi, kwaye phakathi kwamashishini emveliso alindelweyo kulo nyaka, ummandla osemazantsi uhlala uyindawo ephambili yemveliso. Ngokwembono yemithombo yezinto eziluhlaza, zombini ipropylene evela ngaphandle kunye nemithombo esekelwe kwioyile ziyafumaneka. Kulo nyaka, umthombo wemveliso yeoyile yezinto eziluhlaza uhlukahlukene kakhulu, kwaye inani le-PDH liyaqhubeka nokukhula. Ngokwembono yobume beshishini, amashishini asekuhlaleni athatha inxalenye enkulu yamashishini okulindeleke ukuba aqalise ukusebenza ngo-2024. Okwangoku, amashishini amaninzi emveliso ye-polypropylene aphanda kwaye aphuhlisa iimveliso ezikumgangatho ophezulu, ecwangcisa ishishini lokuthumela kwamanye amazwe, kwaye ephucula ukukhuphisana kwawo.
Ngokwezibalo ezivela kuJinlianchuang, kwikota yesibini ka-2024, amashishini emveliso ama-5 aceba ukuqala imveliso, kunye nemigca yemveliso emi-6 iyonke kunye nomthamo omtsha wemveliso opheleleyo weetoni ezi-2.45 ezigidi. Umlinganiselo wemithombo yezinto eziluhlaza zePDH kwikota yesibini ngowona uphezulu. Ekupheleni kukaMatshi, iprojekthi yeSigaba II yeZhongjing Petrochemical ye-1 yezigidi zeetoni ngonyaka ye-propane dehydrogenation yaqaliswa ngempumelelo, kwaye kulindeleke ukuba iqhagamshelwe kwiyunithi ye-polypropylene malunga no-Epreli. Iiprojekthi ze-660000 zeetoni ngonyaka ze-PDH kunye neetoni ezingama-450000 zeetoni ngonyaka ze-PP zeQuanzhou Guoheng Chemical Co., Ltd. zikwindawo yaseNanshan yeQuangang Petrochemical Industrial Zone. Le projekthi isebenzisa ubuchwepheshe benkqubo ye-Oleflex ye-UOP, isebenzisa i-propane njengezinto eziluhlaza kunye nee-catalysts ezisekelwe kwiplatinum ukuvelisa iimveliso ze-polymer grade propylene kunye neemveliso ze-hydrogen ngokusebenzisa iinkqubo ze-catalytic kunye ne-separation; Kwangaxeshanye, sisebenzisa iteknoloji yeSpheripol enelungelo lobunikazi yeLyondellbasell, sivelisa uluhlu olupheleleyo lweemveliso zepolypropylene kuquka i-homopolymerization, i-random copolymerization, kunye ne-impact copolymerization. Iyunithi ye-PDH ye-660000 yeetoni ngonyaka yeshishini kulindeleke ukuba isebenze ngo-Epreli, kwaye iyunithi yepolypropylene esezantsi kulindeleke ukuba iqalise ukusebenza ngo-Epreli. Ngokwembono yemimandla apho amashishini emveliso akhoyo, asasazwa kakhulu eMzantsi China, eMntla China, naseMpuma China. Ngokwembono yamashishini emveliso, amashishini asekuhlaleni athatha inxaxheba enkulu. Gxila kwinkqubela phambili yemveliso yeGuoheng Chemical, Jinneng Technology, kunye neZhongjing Petrochemical kwikota yesibini.
