Separation Technology

In the CPI, separation processes account for a large part of the investment and a significant portion of the total energy consumption. The dominant separation process in the chemical industry (for liquids) is distillation. In terms of cleaner engineering, a goal is to find methods that provide a sharper separation than distillation, thus reducing the amount of contaminated product streams (i.e., waste), improving the use of raw materials, and yielding better energy economy. For this purpose, this section discusses some unconventional techniques that offer the potential for high separation efficiency and selectively.
