Description:

The largest waste stream generated at Phillips Petroleum Companyfs Houston Chemical Complex (HCC) has been the Atactic Polymer stream produced at the Polypropylene Plant. About 5-8 million pounds is generated annually. This material has been beneficially reused as a feed to a boiler unit at the Polypropylene Plant. It produced enough steam to meet the needs of that plant.

P2 Application:

This hazardous waste stream (hazardous due to the characteristic of "ignitability" only) has been eliminated due to the purchase of a new catalyst technology and a massive redesign and installation of new plant process equipment. The "old" plant was shut down in November, 1993, and the "new" plant started production in December, 1993. No Atactic Polymer will be generated as of December, 1993.

Environmental Benefits:

The elimination of this hazardous waste stream accounts for a reduction of 47% of the total hazardous waste generated at the Houston Chemical Complex. The quantity of this wste stream that was generated in 1992 and 1993, and thus now eliminated, was 6.8 million pounds and 3.3 million pounds, respectively. This project will also eliminate the release of about 112 tons of permitted pollutants from the boiler stack and other Polypropylene Plant emission points.
