    The vacuum distillation column internals must provide good vapor–liquid contacting while, at the same time, maintaining a very low-pressure increase from the top of the column top to the bottom. Therefore, the vacuum column uses distillation trays only where products are withdrawn from the side of the column (referred to as side draws ).

  • 10 Things to Know When Specifying Vacuum Conveying Systems

    KNOW YOUR BULK DENSITY. As a first step, it is important to know more about the powder that is being conveyed, specifically its bulk density. This is typically described in pounds per cubic feet (PCF) or grams per cubic centimeter (g/cc). KNOW YOUR CONVEYING DISTANCE. Conveying distances comprise both horizontal and vertical factors. A typical “up-and-in” system offers a vertical lift from floor-level, conveying up to a receiver over an extruder or loss-in-weight feeder. KNOW YOUR CONVEYING RATE. When calculating conveying rates, it is important to know how many pounds or kilograms per hour will be conveyed. Additionally, define whether the process is batch or continuous. KNOW YOUR BULK MATERIALS CHARACTERISTICS. In the plastics industry, there are many different bulk material characteristics, particle shapes, and sizes.

    Vacuum distillation is simply distillation at pressures below one atmosphere. Reduced pressure permits vaporization at reduced temperatures. For instance, at atmospheric pressure water boils at 212°F (100°C); but under vacuum (typically around 27" Hg) this boiling point can drop to 135°F (57°C) or lower. This has two distinct advantages: 1.
