Zydus Lifesciences Executive Production Interview Questions, Process, and Tips for Experienced

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

Pumps and valves are used in various industries for fluid control. There are different types of pumps and valves for different applications.

• Types of pumps: centrifugal, positive displacement, axial flow, and jet pumps

• Types of valves: ball, gate, globe, butterfly, needle, and diaphragm valves

• Pumps are used to move fluids from one place to another, while valves are used to control the flow of fluids

• Centrifugal pumps are ...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

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

• Types include shell and tube, plate and frame, and air-cooled

• Shell and tube exchangers are commonly used in chemical and oil refineries

• Plate and frame exchangers are used in HVAC systems and food processing

• Air-cooled exchangers are used in power plants and natural gas processing

• Heat exchangers are also used in refrigeration and air conditioning s
