'Kua whakatikahia te whakatuwheratanga o te puera mana mamaoa me te arotau ki te 60%, ka tino whakahekehia te kohi mamaoa.' I te 31 o Haratua, i whakahouhia te pourewa ether o te waeine isobutene o Jilin Petrochemical Company, a ka angitu te tiimata, ka hua pai nga hua isobutene kounga teitei.
Kua panaia e Jilin Petrochemical te mahi ki te whakapai ake i te kounga me te whakanui ake i te whai hua ki te hanga uara, i runga i te ahuatanga o te maakete o nga hua isobutylene he pai, me te aro ki te mahi arotautanga-nui o te tipu. Ko te whainga ki te raruraru o te iti o te kaha whakaetonga o te pourewa ether i roto i te tipu isobutylene, ka kitea e nga kaitoi o te roopu rangahau matua te raru o te aukati o te rohe i roto i te paipa hono i waenga i te kettle tower ether me te raro o te reboiler, i pa ki te rere mamaoa. Mo konei, i mahia e nga kaimahi hangarau he kaupapa keri 'mai i raro ki runga, i te tuatahi ki roto, katahi ka puta'' ka karo i te tupono o te toenga coking pakaru ka uru ki roto i te reboiler me te aukati ano.
Ko te wae isobutylene ka nui ake te penapena hiko, i te wa ano ka pai ake te tere o te huringa me te kounga hua o te waahanga. I whakaritea ki mua i te whakatikatika, ka piki ake te tere o te huringa o te waeine i te 0.49% me te ihirangi isobutylene i piki ake i te 0.04%, i whakarite ai i te mahi pumau o te waeine isobutylene, te whakanui ake i te hanga me te kaha ake.
