Control of Air Emissions from Molybdenum Roasting. Volume 1. Emissions Characterization and Particulate Control

摘要

The primary objective of this project was to evaluate a baghouse employing Teflon coated fabric bags for particulate recovery and control. This system was of great interest because of the corrosion resistance of Teflon coated fabric filters and this unique application in the nonferrous metals industry. The Molycorp, Inc. operates the plant at its facility in Washington, Pennsylvania. The plant consists of two multi-level hearth furnaces, a high temperature baghouse and a water quench scrubber. Molybdenum disulfide is oxidized to molybdenum trioxide product and sulfur dioxide.
