Anatomi Distilasi | TRKI SV UNDIP

Summary

This video, presented by Tesalonika Sitepu from TRKI 2019, explains mass and heat transfer in a bubble tray within a distillation column, supervised by Muhammad Endy Yulianto. It details the interaction between vapor and liquid, where vapor enters from the bottom and reflux liquid from the top. The video highlights the process of heat exchange, where volatile components rise as vapor, while non-volatile components condense and move to the next tray. The video emphasizes mass and heat transfer, leading to equilibrium in the distillation process.

Takeaways

• 💡 The presenter, Tesalonika Sitepu from the 2019 TRKI program, explains the mass and heat transfer process in a bubble tray within a distillation column.
• 🌡️ A distillation column facilitates contact between vapor and liquid to separate different components based on boiling points.
• ⬇️ In the process, vapor enters at the bottom tray while a cooler liquid reflux enters from the top, flowing down through each tray.
• ⬆️ The vapor moves upwards through each tray, passing through a riser where it contacts the liquid reflux on the tray above.
• 🔄 The bubble tray design promotes efficient contact between vapor and liquid, enhancing mass and heat transfer.
• 🔥 Heat transfer occurs as the hot vapor rises and meets the cooler liquid reflux, leading to evaporation of the volatile components.
• 💧 Non-volatile components in the vapor condense as they lose heat, transforming back into liquid and flowing down to the next tray.
• 🧪 This process of vapor rising and condensing continues at each tray level, facilitating a consistent mass and heat exchange.
• ⚖️ Over time, equilibrium is achieved between the vapor and liquid phases, optimizing the separation of different components.
• 🙏 The presentation concludes with an apology for any errors and thanks the audience for their attention.

Q & A

What is the main topic of this presentation?

The main topic is mass and heat transfer in a type of distillation tray called a Bubble tray.

Who is presenting the topic?

The presenter is Tesalonika Sitepu from TRKI 2019.

Who is the supervisor mentioned in the presentation?

The supervisor is Mr. Muhammad Endy Yulianto, who holds a degree in engineering and a master's degree in engineering.

What is the primary function of the Bubble tray in the distillation process?

The Bubble tray facilitates contact between vapor and liquid in the distillation column, allowing for effective separation of components through heat and mass transfer.

How does the vapor enter the tray in the distillation column?

The vapor enters the tray from the bottom of the column and moves upwards through the trays.

What role does the liquid reflux play in the distillation process?

The liquid reflux, which is cool, flows from the top of the column downwards through the trays, making contact with the rising vapor.

How does the vapor and liquid interaction happen on the tray?

The vapor rises through the risers in the Bubble cap and contacts the liquid, or reflux, allowing for heat and mass exchange between the two phases.

What happens to the volatile and non-volatile components during this process?

The volatile components absorb heat and evaporate, moving upwards, while the non-volatile components condense and move downwards as liquid.

How does the tray maintain effective liquid and vapor contact?

A barrier called the weir is used to hold liquid on the tray, ensuring adequate volume for effective contact between liquid and vapor.

What is achieved at each tray in the distillation column?

Equilibrium between the vapor and liquid phases is gradually reached at each tray as heat and mass transfer occurs, leading to the separation of components.
