About

CHSP Sieve Trays

A perforated plate with holes is a sieve tray. At the same vapor velocity, a sieve tray has a higher entrainment than a valve tray. Its minimal capacity is at about 70%. They are inexpensive when a low turndown is not necessary. Comparing sieve trays to bubble caps and valve-type trays, they are both more affordable and simpler in design.
Operation, maintenance, and cleaning of sieve trays is relatively easy. In comparison to the other trays, the pressure drop across the sieve trays is lower.

About

CHSP Bubble Cap Tray

A riser (also known as a chimney) is attached to the tray through a hole in a bubble cap, and a cap is mounted over the riser. CHSP Bubble caps are especially suitable for a higher turndown ratio. These work well for small liquid loads. The bubble cap tray is by far the most expensive. A built-in seal on the bubble cap tray stops liquid drainage at low gas flow rates. Because liquid and foam are trapped on the tray to a depth at least equivalent to the weir height, the bubble cap tray can function at low liquid and vapor rates.

About

CHSP Fixed Valve Tray

The fixed valve tray combines the benefits of sieve and float valve trays and makes use of a valve that has been punched out of the tray deck. In contrast to conventional sieve trays, the tapered, rectangular valves are made from the tray deck and are orientated parallel to the liquid flow. This gives them special advantages. Valve trays are adaptable and can be utilized with various feed compositions and rates.
Valve plates can function more effectively than sieve plates at lower flow rates because the area for vapor flow changes with flow rate, and the valves close at low vapor rates.

About

CHSP Float Valve Tray

Float Valve Trays are made up of punched tray decks that have movable valves installed on them to change the tray’s open area in response to shifting vapor loads. Floating valve trays can be used where large turndown ratios are a factor. Valves can have a circular or rectangular lid. They offer higher efficiency than sieve trays across a larger operating range because of their ability to control vapor flow. Different valve types can either have legs built into the valve disc to limit upward movement, or the valve disc movement can also be constrained by a cage attached to the tray panel.

CHSP Cartridge Tray

In flanged columns, where the tower diameter is so small and no manhole is employed, cartridge trays are frequently used. Generally, any tray product with a diameter under 900 mm can be produced using a cartridge-style design. Only 5 trays can be provided per cartridge under this approach, and they are bundled together for simple installation. It is ideally suited for systems that need periodic maintenance as well as fouling and foaming applications.
