Process Equipment and Plant Design
With increase in gas flow rate to fabric surface area ratio (Nm³/hr/m² fabric surface area), the size & the cost of a bag filter
Using split flow, radial flow or cascade flow for column diameter large than 4 ft
All of these
Providing a higher skirt clearance or a higher weir
Decreasing the number of rows of caps through which the liquid flows or by decreasing the velocity of liquid flow past the caps or by reducing the distance along the tray through which the liquid must
