CB&I has been awarded the license and engineering design of a grassroots alkylation unit by PT Pertamina (Persero). The unit will use CB&I's advanced sulfuric acid alkylation technology and Haldor Topsoe's WSA (Wet gas Sulfuric Acid) technology as part of the upgrade of Pertamina's Refinery Unit V in Balikpapan, East Kalimantan, Indonesia. 

CBI’s alkylation technology is an environmentally-friendly alternative process to obtain high-octane, premium gasoline. Because the improved process eliminates the need for human contact with sulfuric acid, it reduces overall maintenance, chemical cost and environmental impact for refineries.
