Descriptions
The production of industrial acetic acid is an intricate and crucial process that is fundamental to many industries. The primary method involves the carbonylation of methanol, catalyzed by Rhodium or Iridium.
Coek is actively involved in fabricating critical equipment for key acetic acid production processes, including the Cativa™ process (Ineos) and Eastman technology.
