Efficiency of Treatment Desired

Maximum pennissible concentrations of individual pollutant, e.g. acid mist, SO2, HCl, NOx, and dust particles in gases going out liom the scrubber—this must meet the standards set by State Statutory Pollution Control Authorities. Separation efficiency desired for particles of different sizes to be informed by plant engineers (say for particles between 1 and 3 p, 3-5 p, microns etc.). Recovery of collected dust if possible (from cyclone, bag filters). 

Pressure drop on gas side during normal operation and at maximum gas flow rate shall be confirmed by vendor. 

Products which are likely to be found in the spent scrubbing liquor-by vendor. Possibility of formation of suspended particles during scrubbing— vendor. Arrangement for cleaning of the system—vendor to inform. 

Can the spent scrubbing liquor be regenerated and reused for scmbbing Power consumption per nm of gases to be treated. 

Operating general arrangement drawing with scope of supply and exclusions from scope of supply— to be informed by vendor.
