The CATOFIN® technology is a unique process for the production of olefins, such as propylene (from propane) and iso-butylene (from iso-butane). CB&I has exclusive worldwide licensing rights to this technology. The catalyst is produced by Clariant, a leading company in the development of process catalysts. Due to its superior thermodynamic operating conditions of vacuum and lower temperature for reactors, CATOFIN provides the highest conversion and selectivity for conversion of paraffins to olefins. Even when co-producing propylene and isobutylene, high conversions can be maintained. The CATOFIN process employs multiple reactors operating in a cyclic manner with an automated program so that the flow of process streams is continuous.
There are six CATOFIN propane dehydrogenation plants operating worldwide, producing more than 3.0 million tons of propylene per year. There are seven CATOFIN iso-butane dehydrogenation plants operating worldwide, producing close to 3.0 million tons of iso-butylene per year. Additionally, two units have been licensed for simultaneous production of propylene and iso-butylene in the same reactor system, demonstrating the unparalleled feed flexibility of the CATOFIN process.
The CATOFIN process uses a single stage of reaction providing the following benefits:
