Kwangelo xesha, amashishini ePetrochemical hlawula ingqalelo yophuhliso eyahlukileyo {● [0}} Iimpawu ezininzi zezinto ezintsha zekhemikhali zishiyiwe kwaye zizinzile {{1} {{5} .
Ishishini lemichiza lemichiza lemichiza, kubini iziphelo kunye nemveliso eluhlaza kwimveliso yemveliso .
Izinto ezingafunekiyo kwinkqubo yomhlaba wonke, ishishini lemichiza le-China le-China likhawulezileyo laza laza laza langathanga le-Olefin, i-Coal-Callids (the Prey-to-Coal kunye nePhezulu leZixhobo eziPhezulu.
Kwisiseko somboniso woNjineli, ubugcisa bezobugcisa bomizi-mveliso ye-Chemical Chemic Chemic e-China iye yakhula ngakumbi, phakathi kwetekhnoloji yokudibanisa i-cecoon, itekhnoloji yokuveza i-cocoon kwaye ikhuthazile inkqubo yokuqhekeza i-cocoon .
Kwelinye icala, imeko ephezulu yophuhliso lweshishini lemichiza lemichiza lemichiza liyabonakala, kwaye iimveliso ziyaqhubeka nokwandisa iimveliso zendlela yokusebenza kunye neekhemikhali ezifana ne-polyalpha-olefin kunye ne-oyile ye-oyile .
Ukongeza, ishishini lemichiza lemichiza lemveli lenza indlela entsha yokuphuhliswa kwezesini .}
Umzi-mveliso wemichiza wemveli ngumzi mveliso wase-China we-China Petrongsical . ishishini le-oyile, i-therigen ye-carcium, i-calcium ye-cartilize, i-pilcinute ye-cartilize, i-Calcium ye-cartilize, i-phoscimize, i-phosphate ye-caltilize, i-phosphate ye-caltilize, i-phosphate i-{2}}
Imizi mveliso yemveli sele ixhomekeke kwimodeli yophuhliso lwendabuko yegalelo eliphezulu, ukusetyenziswa okuphezulu, ukuphuma komgangatho ophezulu kunye nokukhuthaza amashishini aphezulu okuqhuba kunye nokuphuhliswa komgangatho ophezulu. [3).
Ngohlengahlengiso kwiminyaka yakutshanje, ngakumbi kwiBhunga likaRhulumente elikhutshwe "malunga nokwandisa izibonelelo zeSpeysications yokuphucula imeko yohlengahlengiso lwendlela yokuphuhlisa, i-termical yendawo yokuhambisa, yokwahlula-hlula, ukwahlula-hlula, ukwahlula-hlula-mbini. [2}}
