Olefin recovery units
Petrochemical plants and refineries use distillation to separate olefins, e.g. ethane/ethylene, propane/propylene, and butane/butene. The columns used for olefin separation are often referred to as splitters, more specifically C2, C3, and C4 splitters respectively. Because these columns contain a large number of separation stages, they are commonly referred to as superfractionators.
Koch-Glitsch has developed specific thermodynamic packages to accurately represent the subtle nuances of low pressure, medium pressure, and high pressure ethane/ethylene and propane/propylene separations. Koch-Glitsch has created grassroots designs to optimize project economics that include reduced column count and size and minimized energy consumption while providing the maximum throughput capacity. In addition, Koch-Glitsch has participated in numerous revamps to improve the performance of existing assets.
