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
Fractional Distillation Tower
One of the key elements of many process plants is a distillation system. It’s important for operator to understand how distillation system works because its parts of their job to make sure the system is run properly. The purpose of … Continue reading
Reflux System in the Amine Plant
Reflux is a process where a fluid is removed from a vessel, condensed and returned to the vessel to enhance the process. The reflux system consists of reflux condenser, accumulator and pump. Overhead vapor from the stripper mainly consisting of … 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
Glycol Contact Tower Gas Dehydrator Working Principle
Wet gas enters the glycol contact tower through an inlet which located in base and flows upwards through the bubble caps. Dry glycol will flow across the tray from top of the tower; the number of trays which typically installed … 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
