Enhanced Air Finned Cooler For Mechanical Seals

Mechanical Seal Lubrication.......

Mechanical Seals generate heat and require lubrication while face sealing. Different API Plans are used to dissipate this generated heat and cool the seal faces thus extending the seal life.

Flushing is required to cool and lubricate the seal. Controlling Flush Fluid Temperature is critical to the life of a mechanical seal. Cooling of the product also may be needed to improve the margin to vapour formation, to meet secondary sealing element temperature limits, to reduce coking or polymerizing, or to improve lubricity (as in hot water).

Water Based Heat Exchangers...

For the flushing of Mechanical seals, use of water-cooled heat exchangers is a common phenomenon, a shell and tube type of heat exchangers are used in which process liquid flows through the tube while the cooling water flows from the shell and the cooling of process liquid is being achieved.

Disadvantages ......

The basic disadvantages with water-based heat exchangers are the formation of scale around the tube due to fouling. Fouling can be very costly in refinery and petrochemical plants since it increases fuel usage, results in interrupted operation and production losses, and increases maintenance costs.

Solutions...

It has been often recommended to use the Air Cooler to get rid of the above problem but the size and the cooling efficiency of the so far developed air cooler had put them on the back foot and are rarely used for the cooling of the mechanical seals.

Shandilya has developed a new Enhanced Air Finned Cooler for such difficult applications, where no water is used. The compact size with natural draft cooling maintains the requirement of the cooling.
