Sieve trays are the basic type of fractionation tray, typically using ½" diameter holes with an open area between 5 to 15%.
They have a moderate pressure drop with average capacity & separation efficiency.
Sieve trays offer a key advantage of cost. However, flexibility is limited to 2 to 1 and in addition sieve trays are not suitable for fouling services.
Bubble Cap Trays
|
Bubble cap trays are used in applications with very low liquid loading and requiring a very high flexibility (e.g. an operating range of 10 to 1) such as in batch distillations.
Bubble caps are either slotted type or un-slotted type, both in a full range of sizes (2"nb to 6"nb).
Bubble cap trays have a high pressure drop with low capacity & separation efficiency. They are not suitable for fouling services
