Calculation of absorption due to venting from the safety valve of liquid ammonia storage tanks
Thread Content
I’m seeking advice from experts: for a liquid ammonia storage tank with a capacity of 30 m3 and a filling coefficient of 0.9, what should be the capacity of the safety valve’s discharge absorption tank? The known parameters are as follows: the safety valve of the liquid ammonia tank operates at a set pressure of 2.0 Mpa, with a return pressure of 1.8 Mpa; the desired water content in the absorbed ammonia is 10%; the temperature of the liquid ammonia tank is 20 degrees Celsius, and the operating pressure is 0.8 Mpa. What is the required capacity of the absorption tank?
On the right side, the calculation is done in reverse. We currently have a 7m3 absorption tank; could everyone help check whether this derivation formula is correct? Why is there such a big difference in order of magnitude compared to the left side?
