HOUSTON, US: 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.

"K-PRO is a further evolution and extension of KBR's pioneering work in catalytic cracking process technology. In addition, the FCC-based design will deliver higher on-stream factors and much better energy efficiency when compared with existing designs. Our clients have every reason to be excited about this newest addition to our olefins technology portfolio," said John Derbyshire, KBR president, technology.
