BASF: Ethoxylation Plant

,

BASF wanted to improve the safety of its South Carolina ethoxylation plant, so they called on CSA.

In the ethoxylation process, ethylene and propylene oxide react with a variety of alcohols. The reaction is highly exothermic and requires an advance control strategy to prevent a runaway reaction. To enhance security, BASF decided to relocate local control to a central control. They also decided to remove one of their older reactors from service and convert the remaining three reactors to a reactor train.

We were the project manager for all design and installation of instrumentation and electrical equipment. We designed the new control room and specified all DCS and safety PLC equipment. And we developed the functional specification for batch and continuous control strategies.

We configured the DeltaV system and developed the operator display. And we handled start-up services. We stayed on-site until our engineers and the client were certain that everything had been properly configured and was operating as designed. When we left, BASF was delighted with the results, and we felt good knowing we had made the plant so much safer.
