How to perform dynamic cumulative tank calculations
Thread Content
Calculate the dynamic cumulative tank based on the input flow rate; examples are desired
Consider a specific case: a double-headed tank with a diameter of 1X1.42 M, operating at an internal pressure of 0.6 Mpa. The fluid is H2, and the temperature is 25°C. There is a control valve (Cv20) installed at the outlet for pressure relief. The requirement is that the valve opening be very small at first; as the residual pressure inside the tank decreases, the opening increases until the pressure inside the tank reaches zero, at which point the valve opening is at its maximum. It is very difficult to adjust the PID on production equipment, and we hope to solve the problem using CHEMCAD. Could that expert help me out? Chemcad or Aspen will work; thank you.
