Bubble cap tray efficiency
WebBubble-cap trays require extensive labor and more materials to produce than extruded fixed valves, and therefore are significantly more expensive (by a factor of 2–3). Although very common in older plants, bubble-cap trays have fallen out of favor for general distillation use due to their high cost. WebBubble cap trays are generally used when no leakage is allowed. They are also used for low liquid loads and have a very high turndown ratio. ... Discuss the design of a new tray …
