Profile: Tanner Industries, Inc. distributes anhydrous and aqua ammonia. Our support includes supplying anhydrous ammonia and aqua ammonia in tank truck and rail car quantities. We can also provide ammonia storage tanks and technical service and guidance in terms of the safe storage and handling of the chemical and the application of ammonia. Ammonia, both anhydrous and aqua, is injected in the DeNOx or de-nitrification process to reduce the NOx and convert it into nitrogen and water, thus allowing for a cleaner emission through the stack.
