Styrenics / Phenolics / Carbonates Production


The Versalis/Lummus Technology phenol process utilizes advanced technology for the air oxidation of cumene followed by acid-catalyzed decomposition to phenol and acetone. This state-of-the-art technology minimizes heavy by-product formation and maximizes conversion, which improves overall yield while providing smooth, reliable and safe operation. The process features flexible, integrated wastewater and vent gas treatment systems, allowing the plant to conform to local environmental regulations. The process utilizes the latest control systems and operates smoothly, at high yields and low cost, with flexibility and minimal effect on the environment. Maximum heat integration is provided to minimize energy input.
