Summary:Although many offending odors emanating from kraft mill operations can be reduced by operational changes, others require some type of additional mechanical or chemical treatment. Hydrogene sulfide (H2S) is the most commonly known and prevalent odorous gas. It has a characteristic rotten egg odor, is extremely toxic, and is corrosive to metals. A new approach to sulfide control, known as organic scavenger technology, has been developed. This technique involves the use of an organic-based molecule that selectively reacts with any reduced sulfur compounds that have acidic protons. As case studies indicate, organic scavenger technology has proven an effective and economical alternative that avoids damaging problems associated with other chemical treatments, such as increased pH levels, excessive sludge, and corrosion damage to equipment.
