High Purity Ammonia Sample Clauses

High Purity Ammonia. Clean ammonia is just as important as clean air in increasing gauze life and ammonia yields. In this process THE BUYER will use standard commercial grade anhydrous ammonia supply meeting the following specifications: Ammonia: 99.5 wt.% minimum Water: 0.2 wt.% minimum Oil 5 parts per million by weight, maximum Xxxxxxxxx plants utilize a single liquid ammonia filter to remove most contaminants before the liquid ammonia enters the vaporizer system. This filter contains disposable cartridge type elements, which can be easily changed during the catalyst changes. From this point to the gauze, including all piping, the ammonia vaporizer and the auxiliary ammonia vaporizer/superheater, only stainless steel materials are allowed to come in contact with the ammonia. Final vapor ammonia filtering is accomplished using high efficiency, washable sintered metal filter elements similar to those used in the discharge air filter.
