Special Report No. 76-02: Measurement, Fate During Filtration and Contribution of Soluble Sulfide in Lime Mud to Kiln Hydrogen Sulfide Emissions

The attached special report describes the findings of two field studies carried out to determine the effect of lime mud characteristics and composition on lime kiln hydrogen sulfide emissions. The field work is an extension of work recently reported in Atmospheric Quality Improvement Technical Bulletin No. 80 on control of reduced sulfur emissions from lime kilns. The report also includes a modified but simplified procedure for determining the washable or soluble sulfide in lime mud which has been determined to be the critical sulfide component of lime mud for controlling hydrogen sulfide emissions from the kiln. The field work and report were prepared by Dr. Robert P. Fisher and Mr. Michael E. Franklin, both Research Chemists at the Southern and West Coast Regional Centers respectively.
