Kittel trays

Valve tray Kittel tray Novalox Grid Braided metal... 

Specially constructed trays with specially designed vapor openings, cause an increase in the cross flow due to a deflection of the vertical vapor jet (e. g., perforated valve tray, Kittel tray, jet tray, perform contact tray)... 

Tray-type reactors. Intemally, a variety of different tray types may be used. The descriptive terms for these trays include bubble cap trays, flexitrays, ballast tra5 , float tray, sieve trays, turbogrid, and kittel trays. They use a variety of techniques, including sieve slots and holes, as well as caps or fitted mini skirts, to alter the residence time of the fluid that passes over them, thereby enabling a more complete reaction. 

These three types of trays have a common feature in that they all have separate downcomers for the passage of liquid from each tray to the one below. There is another class of tray which has no separate downcomers and yet it still employs a tray type of construction giving a hydrodynamic performance between that of a packed and a plate column. Two examples of this type of device are the Kittel plate and a Turbogrid tray(53). Design data for these trays are sparse in the literature and the manufacturer s recommendations should be sought.
