Moisture Separators: Principles, Operation and Importance

Industrial sectors involve numerous processes and operations that require the intervention of steam operated machines. However, the most common concern engineers confront while working with these machines is when moisture mixes with steam and deteriorates the internal components of the machines. This also adversely affects the overall efficiency and performance of steam operated equipment.

Steam that contains a higher amount of moisture is known as wet steam and technicians are constantly seeking ways to do away with wet steam. In this endeavor, moisture separators play a crucial role in improving the efficiency of the steam machines and overall processes in order to maintain the quality of the end product.

Demister Pad

Demister Pads / Coalescer / Mesh Pad are porous blankets of wire or plastic knitted mesh, designed and constructed for efficient and economical removal of entrained liquid droplets from vapour streams. The pads can be fabricated in any desired size and shape. Normally demister pad is installed in such a way that vapour flow is upward. When vapour and entrained liquid droplets pass through a demister pad, the vapour passes easily but liquid droplets, due to their greater inertia, cannot make the necessary sharp turns and are thrown into contact with the wire surfaces and briefly held there.

Types of Moisture separators:

Here are different types of separators you can choose from based on your specifications and requirements:

1. Baffle Separator : This type of moisture separator is simple when it comes to the design elements and usability. The steam is redirected in one or more different directions with the help of the separator’s one or more internal baffles. This redirection of the steam flow is the reason behind the removal of the heavier condensate droplets from the steam. A drain device (steam trap station or control valve) helps in the removal of this heavy condensate. Though not as efficient as advanced types, the baffle separator is nevertheless popular in simple applications.

2. Centrifugal Separator: As the name suggests, in this type, centrifugal force is used in order to remove the entrained condensate from the steam. In order to get accurate centrifugal separator sizing, it is important that the precise pressure and steam flows are obtained. To get high separation performance, the centrifugal action must not get decreased
