CB&I, through our Lummus Technology unit, offers a diverse line of chemical technologies along product lines such as styrenics and polystyrene, phenolics, light hydrocarbons (C3 -C5  dehydrogenation, butadiene extraction), and other assorted specialty chemicals including dimethyl carbonate, diphenyl carbonate, and maleic anhydride.

We license the most widely used ethylene technology in the world, with about 40% of global capacity based on our process. A significant by-product of the ethylene process when cracking liquid feeds is propylene. Olefins Conversion Technology optimizes the balance among ethylene, propylene and butylenes depending on current market demand and pricing. We also offer the Novolen® gas phase polypropylene process for the production of a full range of polypropylene products.
