The stripping tower in the Snam ammonia stripping process uses (), allowing operation at pressures higher than normal, which improves the decomposition efficiency in the high-pressure circuit. 2. In the synthesis circuit, injectors powered by ( ) are used to circulate the ammonium methoxide solution. 3. The natural stacking angle of granular urea is ( ); the packing density varies with and ( ). 1. The stripping tower in the Snam ammonia stripping process is made of titanium, allowing operation at temperatures above 200 degrees and thereby improving the decomposition efficiency in the high-pressure circuit. 2. In the synthesis circuit, a ejector powered by (liquid ammonia as raw material) is used to circulate the ammonium methoxide solution. 3. The natural stacking angle of granular urea is (37 degrees), and the packing density varies depending on the particle size distribution and (humidity)
