Development & Research Services Interview Questions and Answers

Distillation is a process used to separate mixtures based on differences in boiling points.

• Distillation is a widely used technique in chemical engineering.

• There are two main types of distillation: batch distillation and continuous distillation.

• Batch distillation involves separating a mixture into its components in a series of steps.

• Continuous distillation involves continuously feeding a mixture into a distillation column and separating it into its components.

• Other types of di...read more

There are two types of distillation columns: batch and continuous.

• Batch distillation columns are used for small-scale production and have a single feed inlet and outlet.

• Continuous distillation columns are used for large-scale production and have multiple feed inlets and outlets.

• Examples of continuous distillation columns include packed columns and tray columns.

• Packed columns use packing material to increase surface area for separation, while tray columns use trays to separate...read more

Sulphuric acid has an atomic number of 16.

• Sulphuric acid is a strong mineral acid with the chemical formula H2SO4.

• The atomic number of sulphur is 16, which is the number of protons in the nucleus of a sulfur atom.

• Therefore, the atomic number of sulphuric acid is also 16.

A distillation column is a vertical vessel used to separate components of a liquid mixture based on their boiling points.

• Consists of trays or packing material to increase surface area for vapor-liquid contact

• Operates by heating the mixture to create vapor, which rises through the column

• Different components condense at different heights and are collected separately

• Commonly used in industries such as oil refining and chemical processing

Distillation is a process used to separate components of a liquid mixture based on their boiling points.

• Distillation involves heating the mixture to vaporize the more volatile components, then condensing the vapor back into liquid form.

• Types of distillation include simple distillation, fractional distillation, and steam distillation.

• Simple distillation is used to separate components with significantly different boiling points, while fractional distillation is used for closer ...read more

Acetone's chemical formula is C3H6O.

• Acetone is a colorless, volatile liquid with a sweet smell.

• It is commonly used as a solvent and in nail polish remover.

• Its chemical formula is C3H6O, which means it has three carbon atoms, six hydrogen atoms, and one oxygen atom.

• Acetone is also produced naturally in the human body as a byproduct of metabolism.

Reflux ratio is the ratio of the amount of liquid refluxed to the amount of liquid that is being distilled.

• It is an important parameter in distillation processes.

• It is used to optimize the separation of components in a mixture.

• A higher reflux ratio leads to a higher purity of the distillate.

• Reflux ratio can be calculated using the equation R = L/D, where R is the reflux ratio, L is the amount of liquid refluxed, and D is the amount of liquid that is being distilled.

Distillation is a process of separating components of a mixture based on their boiling points. Different types of valves are used in distillation process.

• Distillation is a process of separating components of a mixture based on their boiling points

• Types of valves used in distillation process include gate valves, globe valves, ball valves, and needle valves

• Gate valves are used for on/off control, globe valves for regulating flow, ball valves for quick shut-off, and needle valve...read more
