Cipla Executive Production Interview Questions and Answers

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

To create a vacuum of 760 mmHg in a reactor, the density of the substance inside must be reduced.

• Reduce the density of the substance inside the reactor by removing any gases or liquids that may be present.

• Use a vacuum pump to remove any remaining gases or liquids and create a vacuum.

• Ensure that the reactor is properly sealed to maintain the vacuum.

• Monitor the pressure inside the reactor to ensure that it remains at 760...read more

BPCR.SOP is a standard operating procedure for batch production, HAZOP is a hazard and operability study, and crystallization, distillation, and evaporation are separation processes.

• BPCR.SOP outlines the steps and procedures for batch production in a consistent and efficient manner.

• HAZOP is a systematic approach to identifying potential hazards and operability issues in a process.

• Crystallization is a process of separat...read more

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

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

• Batch distillation involves separating a mixture into its components in a single batch, while continuous distillation involves a continuous feed of the mixture.

• Other types of distillation include vacuum distillation, steam distillation, an...read more

A packed bed column is a type of chemical reactor used for separation and purification processes.

• Consists of a cylindrical column filled with a packing material

• Fluid is passed through the column and interacts with the packing material

• Used in various industries such as chemical, pharmaceutical, and food processing

• Examples include distillation columns and gas absorption columns

Centrifugal pumps work on the principle of converting rotational kinetic energy into hydrodynamic energy.

• The pump has an impeller that rotates and creates a centrifugal force, which pushes the fluid towards the outer edge of the impeller

• The fluid then enters the volute casing, where the kinetic energy is converted into pressure energy

• The pressure energy then forces the fluid out of the pump and into the piping system

• Ce...read more

Bernoulli's equation relates the pressure, velocity, and height of a fluid in motion.

• The equation is based on the principle of conservation of energy.

• It is commonly used in fluid mechanics and aerodynamics.

• The equation can be used to calculate the pressure difference between two points in a fluid flow.

• It is also used to explain phenomena such as lift in airplane wings and the flow of blood in arteries.

• The equation is n...read more

Heat exchangers are devices that transfer heat between two or more fluids.
