Long-distance transportation of ammonia water and liquid ammonia
Thread Content
Ammonia solution at a concentration of 20% is pumped under normal pressure to the recipient’s storage tank, where the liquid ammonia is at a pressure of 1.8 MPa. The distance between the two pipelines is 7 kilometers. 1. The highest temperature in summer is 40°; to ensure product quality, is it necessary to insulate the pipelines? 2. If insulation is used solely to prevent corrosion, can 304 material pipes be used directly? Thank you all
I’ve never worked with this before, but liquid ammonia probably does require cooling
40 degrees Celsius is already above the boiling point of 20% ammonia solution
