Taiwan’s CPC plans to shut its No. 6 naphtha-fed steam cracker at Linyuan over February-April for planned maintenance. The maintenance program is expected to start on February 13 and end on April 10, lasting about 56 days. The cracker is able to produce 720 kta of ethylene and 430 kta of propylene. According to latest data by the Chinese customs department, China’s propylene imports rose 33.3% month on month to 293,410 ton in November. The rise in Asian propylene prices has led to a wider spread between propylene and feedstock naphtha.
