Tower Internals

To achieve the desired performance of the packed column the use of the properly designed column internals play the most important role. These are tailor made units, designed to achieve the optimum results.
 
Liquid Distributors
 
Uniform initial liquid distributors at the top of the packed bed are essential for the efficient column operations.  This is accomplished by the devices called distributors, which spreads the liquid uniformly across the top of the packing. If the disrtibution is not desinged properly the mal distribution  cau cause channeling and by passing of the liquid and gas resulting in poor performance of the colmun.

BED LIMITERS
The primary fuction of the bed limiter is to retain the packed bad i.e stops escaping of packing & avoids expansion of packed bed.

Packing Support
While primary purpose of the support plate is to retain packing without execssive restriction to gas and liquid flow, streams, unless carefully designed, the suport plate can cause premature column flooding. Thus design of the support drop and stable operating range.

Demester Pads
These are metal/pp wire kinitted pads wwith maximum opening and contact surface. Useful to trap liquid droplets esacping alng with vapor. Thus i prevents high boiler products droplets carry-over into low boiler top condenser.
