Abstract
Method for the reduction of emissions from the wet quenching of incandescent coke in a quenching tower adapted to receive in its base a quench car containing the coke which comprises positioning the car with the coke in the quenching chamber of the tower, effecting a gas seal to substantially prevent air from infiltrating the quenching chamber and ascending the tower, quenching the coke with the resultant generation of steam and other quenching emissions, cooling and cleaning the emissions with water sprays, demisting the cooled emissions, sensing the external and internal pressures of the tower during the quenching process, maintaining a substantially zero gauge internal pressure by controlling the emissions flow exiting the tower and collecting, cooling and recycling the quenching and cooling waters. Apparatus for practicing the method is also disclosed.
