2021.7.1 Lime recovery kiln operators are concerned with contamination and emissions. Therefore, the sulfur levels in petcoke-typically 3 to 5% by weight-can have significant impact. For a 300-tpd kiln operation, the sulfur load would be approximately 13 to 26 lb/hr, and this is captured in either the kiln product or the exit gas cleanup system.
