Bubble cap Tray

The operating range of this tray, the oldest one in history, covering 10:1 is so wide that one can operate it very eas Also if this tray is sealed completely without weeping, it's duration period can be lengethed along with sufficnet hydraulic head, enabilng it to be operated with a high contact efficiency. It is also recommended for operating a column with a wide operating range at a low load condition.

Becasue of its structual particulars, it needs to be of bigger diameter than any other trays for treating vapor of same quantity, In other word, its capacity is comparatively small, its pressure drop is high and its maintenance cost is high

Sieve Tray

Developed in 1950th, this tray has a less capacity but higher efficiency than the bulle cap tray. Its capicity is similar to the valve tray. As its pressure drop is lower than otehr trays, it can be used for the vacumm tower. In case of liquid with bad fouling, one can resolve the fouling problem with a hole of 3/4"~1".

Because of its simple structure, it does not need a big investment at the early stage. This tray has come demerits. its operating range is small(2:1), its efficiency is decreased in case of weeping and it may face with severe vibration when operated for low vapor. As the space of this tray is not big enough for safe opration, one should be awere of any load changes of liquid and vapor.

Valve Tray

This is the tray most favorite to its users these days. Developed to improve the small operating range of the sieve Tray. this valve has its operating range covering 7:1. Compared to the sieve tray, it is made of higer efficency, lower pressur drop. Its capaciry is bigger than any others and its cost is less expensive than the bubble cap tray. As its demerits, it could face with plugging and there after, very difficlut to be cleaned.
