Technology Fact SheetFor Further Information Contact:Media: Jan Sieving +1 832 513 1111 April 14, 2011Butadiene Technology from Lummus/BASF used in IndonesiaOwner :Location:Process:Capacity:Technology:Description:CB&I Advantage:Benefits:PT Chandra AsriAnyer, West Java, IndonesiaButadiene100,000 metric tonnes per annumThe BASF NMP-based butadiene extraction process, licensed byLummus TechnologyThe butadiene extraction process utilizes n-methylpyrrolidone (NMP) asa solvent. NMP is less toxic and more stable compared to othersolvents, providing the best properties to maximize recovery ofbutadiene, resulting in high purity butadiene product and low operatingcosts.The BASF NMP-based butadiene extraction process, licensed byLummus Technology since 1990, is the preferred technology for theproduction of high purity 1,3-butadiene from crude C4 cuts. Thetechnology is successfully applied in more than 30 plants worldwide, witha total capacity exceeding three million tons per year. These advantagesminimize start-up costs, maximize production, ensure high profitability,and achieve short payout time. New plants have started up at anaverage rate of two per year since 1989.FEATURESNMP is non toxic, non carcinogenic andcan be treated by conventionalbiological waste water treatmentNMP and water mixtures are noncorrosiveallowing carbon steelequipment to be used without the needfor a corrosion inhibitorLow solvent losses due to NMP’sremarkable resistance to hydrolysis andthermal decomposition as well as itshigh boiling pointBENEFITSEnvironmentally sound designLow investment and operating costsLow operating costs • Less fouling

Low energy consumption due to anefficient het recovery system andoptimal process designOperating periods exceeding four yearswithout cleaning due to effective foulinginhibitor systemLow operating costsLonger on stream time • Lowmaintenance costsAbout CB&ICB&I (NYSE:CBI) engineers and constructs some of the world’s largest energy infrastructureprojects.
