Dear experts: Could you please share the liquid filling time for your nitric acid plant absorption towers, the processes used, as well as specific details regarding the pressure in those absorption towers and the flow rate of the deionized water?

Our plant uses a dual-pressure system with a capacity of 15W tons; the flushing time is only 1.5 hours. Flushing is completed when the pressure difference in the absorption tower remains constant, at around 0.045 MPa. Desalinated water flow: 24 cubic meters per hour

Around 2 hours; it’s fine as long as the pressure is above 50 KPa
