Technology

The Proprietary Selective Cracking Optimum REcovery (SCORE) Pyrolysis Furnace features a single Straight Radiant-Tube design with Feed entering the bottom and Cracked Gas leaving the top of the Furnace. This results in low practical Reaction Time (~0.1 seconds) in the industry, low Operating Pressures, and high Olefins Yields. Additional features of the SCORE process are Hybrid Cracking, Online Decoking and ultra low-NOx Burners. The Recovery Section is based on a Front-End Acetylene Reactor design pioneered by KBR combined with integration of Fractionators with the major Compressors. Ethylene yields to 84% for Ethane, 38% for Naphtha and 32% for Gasoils may be achieved depending upon Feedstock character. Overall Specific Energy per Ton of Ethylene range from 3,000 kcal/kg to 6,000 kcal/kg, depending on Feed type and Battery Limit conditions.
