TOKYO (ICIS)--Japanese chemical producer Asahi Kasei Chemicals has developed a new butadiene production technology and is considering building a 50,000 tonne/year plant at Mizushima around 2014, a company source said on Friday.
The new technology, called BB-FLEX, produces butadiene from butene, while with the company’s existing technology butadiene is produced from the C4 fraction which comes from the naphtha cracking process, the source said.
“The butadiene price was rising sharply until recently. We have developed BB-FLEX to obtain [butadiene] feedstock for synthetic rubber at a low cost because it yields more butadiene [than the existing technology],” the source said in Japanese over the telephone.
“We want to strengthen our synthetic rubber business, and we are planning capacity increases [of synthetic rubber plants]. So it is important to procure butadiene at a low cost,” the source added.
While the plan had not been finalised, it would be “most effective” to build the butadiene plant, using BB-FLEX, in Mizushima, ?xml:namespace>
“If we can get approval, we may also build a [butadiene] plant overseas,” the source said.
Asahi Kasei Chemicals plans to use butadiene from the new plant to produce synthetic rubber, the source said.
The company also operates a S-SBR/low-cis BR swing plant at
