Abstract

See full text

The present process relates to thermally hydrolyzing sludge in a thermal hydrolysis system. A flash tank or waste heat boiler is located downstream of the thermal hydrolysis system. Hydrolyzed sludge is continuously directed into the flash tank or waste heat boiler for recovering supplemental steam. The supplemental steam is used independently or in combination with live steam produced by a main boiler to heat sludge being directed into the thermal hydrolysis system.
