Could any teacher help me design this? Thank you! Original design parameters for the flash tank: Physical properties of the material: (sewage, containing approximately 9%–10% fine particles and a small amount of fibrous impurities). Density: 1057.1 kg/m3. Dynamic viscosity: around 15 mPa·s. The system features two stages of flashing: Original design parameters for the first flash tank (all pressures are gauge pressures): Material flow rate into the flash tank: 26.08 tons per hour ； Material pressure entering the flash tank: 0.45 MPa ； Rated internal pressure of the flash tank: 0.1 MPa ； Could any teacher help me design this?

Original design parameters for the second flash tank (all pressures are gauge pressures): All the material that has passed through the first flash tank enters the second flash tank ； Material pressure entering the flash tank: 0.1 MPa ； Rated pressure inside the flash tank: atmospheric pressure ； Steam is introduced into other containers through pipes, while the material is discharged. Composition of the flashed material:  Slightly acidic, with a pH value of around 6.7 ；  Chloride ion concentration: 100-150 mg/L  Ammonia concentration: 2500-3000 mg/L.
