Correction: In the ICIS news story headlined " Propylene costs expected to surge in cumene production" dated 8 November 2011, please read in the last paragraph ... expected to grow by 4%... instead of …expected to grow by 3%... A corrected story, with recast first paragraph, follows.
SINGAPORE (ICIS)--The relative balance between the costs of feedstocks propylene and benzene in cumene production is expected to shift to an almost 50:50 ratio depending on crude oil prices, a consultant from Nexant Asia said on Tuesday.
By 2015, the average costs for cumene production are expected to be about $600/tonne (€438/tonne) of benzene and about $550/tonne of propylene, Tiankanok Sirichayaporn said at the 1st ICIS Asian Phenol-Acetone Conference in ?xml:namespace>
The chemical ratio for cumene production is roughly 0.67 parts benzene and 0.37 parts propylene, he said.
The biggest reason for the shift in the ratio is expected to be continued global tightness of propylene because of a shift towards lighter cracker feedstocks, particularly ethane, he added.
Cumene production will have to compete with the production of polypropylene (PP), which is expected to grow by 5-6% as a propylene derivative, Sirichayaporn said.
Cumene is expected to grow by 4% as a propylene derivative, he added.
The 1st ICIS Asian Phenol-Acetone Conference is held on 8-9 November.
