Phenols cyclones

The catalyst dust is then separated from the resulting carbon dioxide stream via cyclones and/or electrostatic precipitators and is sent off-site for disposal or treatment. Generated wastewater is typically sour water from the fractionator containing some oil and phenols. Wastewater containing metal impurities from the feed oil can also be generated from the steam used to purge and regenerate catalysts. [Pg.90]

The range of components found in the gas are typical of those found in downdraft gasification systems (6), Analysis of the process gas after the cyclone indicates that there are no measurable amounts of phenols or methoxyphcnols present suggesting minimal bypassing of pyrolysis products through the gasification zone.
