Reduction of malodorous emissions from chemical tar dumps or pitch lakes during e.g. ground remediation or fuel recovery, comprises covering deposits with layer of moist brown coal fines

摘要

Malodorous emissions from tar dumps during e.g. ground remediation or fuel recovery, are reduced by covering the deposits with a layer of brown coal granules, of 0-30 mm particle size, and 30-60% moisture content, to a depth of at least 1 cm.
