Bubble Cap and Packing Distillation Tower

In trays and bubble cap distillation tower the holes in each tray are covered with caps called bubble caps. The slots in these bubble caps disperse the raising vapor through the liquid on the tray. Each bubble cap has many … Continue reading

Reboiler in Distillation Column

Another method uses to increase the purity of the product is called re-boiling. The bottom liquid that is drawn off of the tower is sent to a heater called re-boiler. The rest of bottom liquid is sent to storage or … Continue reading

Reflux in Distillation

If the distillation tower works perfectly, it would produce a pure product but unfortunately the lighter products usually contain some heavier fraction while the heavier products contain some lighter fraction, this chase is sometimes referred to as overlap. Distillation system … Continue reading

Distillation Tower Sections

Every distillation tower can be divided into three different sections. The middle section is where the feed enters the tower and part of the feed vaporized. This vaporization is commonly known as flashing, so this section of this tower is … Continue reading

Carryover in the Amine Plant

There is usually space in overhead system for separation, where most of the entrained amine solution particle in the vapor stream will settle out. Amine solution not settling out will be removed by mist eliminator. This prevents liquid amine from … Continue reading

Gas Dehydration Methods

Before gas can be sold the gas need to be dehydrated from its water content. This efforts need to be done to prevents hydrates and water vapor. The water vapor in gas line could create corrosion problems. There are many … Continue reading

Moody Friction Factor

The factor of proportionality in the previous equations is called the  Moody friction factor and is determined from the Moody resistance diagram shown in Figure 8-1. The friction factor is sometimes expressed in terms of the Fanning friction factor, which … Continue reading
