KBR has been a leader in olefin plant design and construction and technology development for over 50 years. We provide cost-effective plants for the production of ethylene, propylene, butadiene and other by products from petrochemicals feedstocks ranging from ethane to vacuum gas oils. Since 1990, over 20 new ethylene plants have been brought on-stream using KBR technology, producing a combined ethylene capacity of 13 million metric tons per year. Through continuous improvement and technology innovations, KBR SCORE™ Technology has become the preferred choice for many major ethylene producers.
KBR's extensive olefins experience, combined with an exclusive license agreement to utilize ExxonMobil Chemicals ethylene technology developments, is the basis for our olefins plant designs under the trademark SCORE™, Selective Cracking Optimum REcovery. SCORE technology features:
KBR, as a SCORE technology licensor, combines the expertise and experience of ExxonMobil to offer the petrochemical industry state-of-the-art thermal naphtha cracking technology that features:
Selective Cracking is KBR's pyrolysis furnace technology. SCORE olefins process features the short residence time SC-1 furnace design that provides the highest yield selectivity to light olefins in the industry and a highly reliable mechanical design. The selective SC-1 furnace design can be used to crack feeds ranging from ethane to vacuum gas oils.
SC-1 furnaces have the following benefits:
SC-1 furnaces have a unique and reliable design featuring:
Optimum REcovery is KBR's olefins product recovery section technology. Our technology incorporates advanced, proven features to help our clients achieve the optimum balance between operating and capital costs. KBR offers three recovery section flowsheets, all of which are proven in commercial operation in numerous KBR plant designs over many years.
The deethanizer-first flowsheet is KBR's primary offering for ethane and E/P feeds. The depropanizer-first design is KBR's primary offering for propane and all heavier feeds and is also flexible to ethane feeds. The demethanizer-first flowscheme can be used for propane, petrochemical naphtha and gas oil feeds and for ethane feeds where flexibility to heavier feeds is a design requirement.
Each of these recovery section designs has been optimized through the use of PINCH technology and lost work analysis and the implementation of pre-separation and distributed distillation concepts to reduce energy consumption and capital costs. Throughout the optimization process, KBR has paid special attention to maintaining flexibility and operability of the recovery system.
KBR's SCORE recovery flowsheets provide the following benefits:
