Deedy Chemicals Production Interview Questions and Answers

Mass transfer is the movement of substances from one place to another.

• Mass transfer involves the movement of components in a system due to differences in concentration, pressure, or temperature.

• Examples include the diffusion of gases in air, the separation of components in distillation processes, and the absorption of gases in liquids.

• Mass transfer is important in various industries such as chemical engineering, food p

Distillation is a process of separating components of a liquid mixture based on differences in boiling points.

• Distillation involves heating the liquid mixture to create vapor, then cooling the vapor to condense it back into liquid form.

• The components with lower boiling points will vaporize first and be collected, while the components with higher boiling points will remain in the liquid phase.

• Common examples of distilla...read more

Types of pumps include centrifugal, reciprocating, and rotary pumps. Troubleshooting involves checking for leaks, low flow rates, and abnormal noises.

• Centrifugal pumps use rotating impellers to create flow.

• Reciprocating pumps use a piston or diaphragm to create flow.

• Rotary pumps use rotating mechanisms to create flow.

• Troubleshooting involves checking for leaks in the pump system.

• Troubleshooting involves checking for lo...read more

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

• It involves heating the mixture to vaporize the component with the lowest boiling point.

• The vapor is then condensed and collected as a separate liquid.

• This process is commonly used in the production of alcoholic beverages, petroleum refining, and purification of water.

• Fractional distillation is a variation of distillation that...read more

To convert from kg to gm, multiply the value by 1000.

• Multiply the value in kg by 1000 to get the value in gm.

• 1 kg = 1000 gm

• Example: 2 kg = 2000 gm

To convert from meter to centimeter, multiply the value by 100.

• Multiply the value in meters by 100 to get the value in centimeters.

• 1 meter = 100 centimeters

• Example: 2 meters = 200 centimeters

A pump is a mechanical device used to move fluids from one place to another. There are various types of pumps.

• Types of pumps include centrifugal pumps, positive displacement pumps, and axial flow pumps.

• Centrifugal pumps work by converting rotational energy from a motor into kinetic energy in the fluid being pumped.

• Positive displacement pumps work by trapping a fixed amount of fluid and then forcing it into the discharg...read more

Reactors are vessels used for chemical reactions. Types include batch, continuous, CSTR, PFR, and fluidized bed.

• Batch reactors are used for small-scale production and testing.

• Continuous reactors are used for large-scale production.

• CSTR (continuous stirred tank reactor) is commonly used in the chemical industry.

• PFR (plug flow reactor) is used for reactions with a high heat of reaction.

• Fluidized bed reactors are used for...read more
