reclaimers, while Kenney et al. (1994) recommend 8 to 12 inches for DGA. Since the
reclaimer sludge. is quite viscous, the dump valve should be a minimum of 3 to 4 inches
(pipe size) to prevent plugging of the drain line (Jefferson Chemicals, 1963; Kenney et al.,
1994). In many jurisdictions, the reclaimer sludge is regarded as a hazardous waste. Provid-
ing a dedicated underground sump for reclaimer sludge storage can facilitate disposal and
minimize operator exposure.
A manway should be provided at the top of the kettle to provide access so that the kettle
can be hosed down at the end of the reclaiming cycle. To minimize corrosion, steam spargers
