Description:

Four internal floating roofs were installed at the Hoechst Celanese Chemical Group, Inc., Bay City Plant (BCP) during 1993. The roofs were installed in the isobutanol and normal butanol storage tanks.

P2 Application:

During the first installation, the roof had to be installed under extremely tight timing which required the work be installed using a 24-hour a day work schedule for two tanks for 7 days. The standard seal material used for the seal was not compatible with material inside the tank and the manufacturer had to produce a special elastomer for the seal materials. These seals were double wiper with a teflon cloth overwrap. A nitrogen blanketing system was installed in all of the tanks to reduce enhance the safety of the storage tanks.

Environmental Benefits:

The purpose of installing the internal floating roofs was to reduce air emissions from the Bay City Plant by 24 tons/yr. This project was a part of the plant Waste and Release Reduction (WARR) effort for 1993. Prior to the floating roof installation, the chemicals were stored at atmospheric pressure in cone roof storage tanks and emitted 26 tons/yr of chemicals to the atmosphere due to evaporative vapors escaping to the atmosphere.

Details of Reductions

Additional Information :

The project was completed in November 1993 on-time and within budget. There have been no problems since installation.
