Abstract
The Advanced Recovery System (ARS) is a patented process that uses the principle of distributed distillation to achieve energy efficiency in the olefins process. This paper describes the concept of ARS and how, by integrating the chill-down and cryogenic fractionation steps, the technology can significantly reduce refrigeration power requirements. ARS technology can be applied to revamps of existing plants as well as new plant designs. Additional applications are now being considered in the integration of refinery off-gas streams with other olefins process.
