Distillation Equipment and Tray tower – Scube mass Transfer Types of Tray Special tray selection and its design can materially affect the performance of a given distillation, absorption, or stripping system. Each tray should be designed to provide as much contact as possible between vapor and liquid within reasonable economic limits. Scube Mass Transfer is a leading supplier of Distillation Equipment’s and Tray towers in India Types of Tray available are SCM Valve Tray, SCM Sieve, Tray, SCM Bubble Cap Tray. A] SCM Valve Tray Valve trays are perforated sheet metal decks with round, liftable valves. Vapor flows through valves that are installed parallel to the outlet weir. The vapor caps the flow, thus creating a flow field for the passage of vapor. The lifting cap directs the vapor to flow horizontally into the liquid, thus it is possible to provide better mixing in the sieve tray. The Valve trays combines high capacity and excellent efficiency with a high operating range. Fixed Valve Trays Floating Valve Trays Advantages: • • • • •
Excellent liquid/ vapors contacting. Higher capacity. Higher flexibility than sieve trays. Can handle higher loadings. Low-pressure drop than bubble cap.
B] SCM Sieve Tray Sieve trays are flat perforated plate in which vapour rises through small holes in tray floor, & bubbles through liquid in fairly uniform manner. They have comparable capacity as valve trays Vapour passes straight upward through the liquid on the plate. The arrangement, number and size of the holes are design parameters.
