Packed tower absorption liquid

Thread Content

Title: Design of the exhaust gas absorption tower in an ammonia synthesis plant. Original data: The flow rate of the mixed gas is 22,000 kg/h; the gas temperature is 25°C and the pressure is 0.25 Mpa. Its properties can be assumed to be those of air. The flow rate of the absorbent liquid is 16,000 kg/h, ρ is 1,220 kg/m3, and the viscosity is 1.07 cP (1.07 mPa·s). A 38 mm steel Pall ring is used as the packing, with a flooding ratio of 0.7 and a packing layer height of 16 m. Wind pressure 350 Pa, near-fault intensity of degree 8, soil type II. What is this absorbing solution? The density of formic acid is the same, but the viscosity value available is 1.9 mPa·s at 20°C. Any other questions? I don’t know the composition of the inlet and outlet gases; I can only calculate the SM value. I’ve only managed to determine the inner diameter of the tower. Since this setup differs from what’s described in the manual, there are many problems at each step of the calculation. I hope someone can help me.
