Traykolonner
Traykolonner are a type of distillation column that use a series of perforated trays to promote contact between rising vapour and descending liquid. The trays provide surfaces where mass transfer can occur, improving the separation of components with different volatilities. The Swedish term is often used in engineering contexts to distinguish plate (tray) columns from packed columns.
Operation in a tray column begins with feed entering the column. Vapour rises through the trays, while
Common tray designs include bubble-cap trays, sieve trays, and valve trays. Bubble-cap trays use caps to break
Tray columns are often compared with packed columns. Tray columns offer easier control and good performance
Design and analysis commonly use methods related to theoretical stages and tray efficiency, with the McCabe–Thiele
