Questions regarding the selection of vacuum pumps for eco-friendly plasticizers with an annual production capacity of 20,000 tons
Thread Content
I need help selecting a vacuum pump. The pressure at the top of the tower is 12,000 Pa(A), the flow rate is 1,038 Kg/h, and the density of the material is 0.077 Kg/m3. The non-condensable gas in this material is hydrogen, accounting for 0.0037% of its composition; the rest is water. The vacuum level at the inlet of the vacuum pump should be 7,000 Pa, with an inlet temperature of 40°C. Leakage rates also need to be taken into consideration. What size or type of vacuum pump should be selected?
A vacuum pump with a capacity of 200 is sufficient; it can be a vertical oil-free pump or a Roots vacuum pump.

Could you tell me exactly how to calculate it? Thank you :)
