Ours is a solid liquid reaction. Solids & liquids are charged at atmospheric condition. We obtain vacuum in the system with the help of oil ring vacuum pump. The vacuum pump require regular maintenance in terms of oil seal leakages and presence of powder in the pump.

 

We intend to use a vacuum catch pot and a demister pad to overcome this problem. The vacuum pump capacity will be 250 m3/hr.

 

Are we in the right direction/ or better suggestions are available. If, further data is required we can share the data.

One option maybe to use a "liquid ring vacuum pump" system.  This may better cope with dust and contaminants, but needs a once through or recirculating seal water system, and will then produce an aqueous effluent stream.

 

Even with this system an inlet knock-out vessel would be beneficial.

 

I would not use a demister pad as it will block with the solids unless you also install sprays to flush the pad regularly to wash out or dissolve the solids.
