Bubble caps regulate vapor flow inside distillation columns to improve separation efficiency and liquid-vapor contact. They allow vapors to diffuse uniformly across trays for consistent performance. These components suit distillation towers in distillery systems and chemical processing columns needing enhanced mass transfer. Reliable bubble caps support stable column operation and increased distillate purity.

Copper Bubble Plate 3″ Distillation Glass Reflux Column For Moonshine
The trays have openings to allow vapor to flow upward through the column, as well as conduits (downcomers) to allow condensed liquid to flow downward. The tray is designed to promote intimate contact between the upward-moving vapor and downward-moving liquid. Each tray effects a portion of the separation before the vapor and liquid move to the next tray in the column until the desired concentrations (purities) are reached. Common types of trays include bubble-cap trays.

SS304 Bubble Cap Trays Distillation Column Internals Stainless Steel
A bubble cap tray has riser or chimney fitted over each hole, and a cap that covers the riser. The cap is mounted so that there is
a space between riser and cap to allow the passage of vapour. Vapour rises through the chimney and is directed downward by the
cap, finally discharging through slots in the cap, and finally bubbling through the liquid on the tray.SKU: n/a
