WATER QUALITY CRITICAL TO AQUEOUS AMMONIA SCR PERFORMANCE

摘要

Topping the list of the most important concerns related to the operational aspects of ammonia-based selective catalytic reduction (SCR) systems is the quality of aqueous ammonia and its potential to damage catalytic elements of the SCR. Yet according to Dustin Divinia, director of operations for Richardson, Texas-based Vector Systems, Inc., there are a number of other concerns associated with using poor quality ammonia, the greatest of which is the propensity for the buildup of mineral deposits in handling and vaporization equipment.
