Aurobindo Pharma Executive Production Interview Questions, Process, and Tips

It is important to check all RM, equipment, and utility before batch charging to ensure quality and safety.

• Inspect all raw materials for quality and quantity

• Check equipment for cleanliness and proper functioning

• Ensure all utilities (water, electricity, etc.) are available and functioning properly

• Verify that all safety measures are in place

• Perform necessary calibrations and validations

• Document all checks and inspections

Vacuum distillation is a process of separating components of a mixture by boiling it under reduced pressure.

• It is used to separate components with high boiling points.

• The process involves heating the mixture in a vacuum to lower the boiling point.

• The lower pressure also reduces the risk of thermal decomposition.

• Vacuum can be created using a vacuum pump or aspirator.

• Examples include the separation of crude oil into diff...read more

There are various types of distillation methods such as simple distillation, fractional distillation, steam distillation, vacuum distillation, etc.

• Simple distillation is used to separate liquids with different boiling points

• Fractional distillation is used to separate liquids with similar boiling points

• Steam distillation is used to extract essential oils from plants

• Vacuum distillation is used to distill high boiling poi...read more

The type of packing that is better in distillation depends on the specific application and desired outcome.

• Structured packing is better for high efficiency and low pressure drop

• Random packing is better for high capacity and fouling resistance

• Trays are better for high turndown ratio and easy maintenance

• Factors to consider include composition of the mixture, desired separation efficiency, pressure drop limitations, and c...read more
