KBR develops new propane dehydrogenation technology




KBR Inc has developed a new propane dehydrogenation (PDH) technology (K-PRO) that offers high propylene selectivity and conversion. This technology is based on KBR's catalytic olefins technology (K-COT) which is a commercially proven fluidized-bed technology for converting low-value olefinic, paraffinic or mixed streams into high-value propylene and ethylene.
K-PRO delivers significant capital cost and operating cost advantages when compared with conventional designs. This arises from its fluidized-bed design which delivers reliable operation and high on-stream factors when compared with fixed or moving bed reactors.
K-PRO technology combines the know-how and experience of K-COT with a novel high selectivity, low-cost, dehydrogenation catalyst that does not require precious metals. Plants based on this new technology will be designed as stand-alone propylene production units independent of a steam cracker or an FCC unit. Additionally, existing PDH operating units can be easily modified to benefit from the superior process performance and lower operating cost.
