Olefins are a class of chemicals such as ethylene, propylene and butylene. Olefins are the building blocks for a wide variety of products such as plastics, rubbers and solvents. They are produced from natural gas liquids and refinery products such as naphtha, kerosene and gas oil.
CB&I offers a variety of licensed processes to produce and recover olefins as well as to convert them to higher valued products such as polyethylene, polypropylene and alkylate. Olefin producing technologies include steam cracking, fluid catalytic cracking (FCC) and catalytic dehydrogenation (CATOFIN®). Light olefins recovery technology recovers olefins from methanol to olefins plants or from refinery offgases. Olefins conversion technology (OCT), ethylene dimerization and comonomer production technology (CPT) balance petrochemical feedstock and product demand by interconverting light olefins to the desired olefins.
CB&I, a leader in ethylene technology, provides innovations proven in more than 120 ethylene plants operating around the world, accounting for about 40% of the world's ethylene capacity.
CB&I's Novolen® technology licenses the gas-phase polypropylene process worldwide on the basis of Ziegler-Natta and metallocene catalysts for the production of a full range of polypropylene resins.
CB&I offers two on-purpose routes to propylene: olefins conversion technology, which utilizes olefins metathesis, and CATOFIN® propane dehydrogenation.
The BASF NMP-butadiene extraction process offered by CB&I is the preferred technology for the production of high purity 1,3 butadiene from crude C4 cuts. The process has been successfully applied in more than 30 plants worldwide.
