Judgment questions: 1. The ammoniation of refined brine mainly absorbs ammonia, and the absorption of carbon dioxide is secondary. ( )2. The ammonia absorption process is an exothermic process. ( )3. In order to reduce the heat load of ammonia absorption, the temperature of the refined brine should be kept low, and the temperature of the ammonia should also be kept low. ( )4. The scars in the ammonia absorption system are gray and black, mainly because they contain FeS. ( )
