16. What Is The Method Adopted To Minimize Shell Side Pressure Drop In A Shell?
The method of protecting the shell from the pressure drop is very essential as it is very critical stage, where if not taken care properly the shell has to be replaced due to its degradation. In this rods or tube protectors are used instead of plates in top rows. The use of these rods puts less pressure drop and provides better distribution of the pressure on the plate. The plate that is used causes an abrupt of 90 degree turn of shell stream and an extra pressure drop on the whole shell. Use of the tube protectors will allow the shell to be saved from this and maintains its longevity.
