Q1. What is distillation, types of distillation, internal of distillation column, Do you know DCS/PLC
Ans. 
Distillation is a separation process used in chemical engineering to separate components of a liquid mixture based on their boiling points.
• Distillation is a separation technique used to purify liquids or separate liquid mixtures.

• It relies on the differences in boiling points of the components in the mixture.

• The process involves heating the mixture to vaporize the more volatile component and then condensing it back into...read more

Q5. How to start pump, what is two phase flow is there in pipe, control station work, ejector problem and troubleshooting, why we need vacuum in column
Ans. 
Answering questions related to starting pump, two phase flow, control station work, ejector problem and troubleshooting, and vacuum in column.
• To start a pump, ensure that the suction line is filled with liquid and open the discharge valve. Then, turn on the motor and gradually open the suction valve.

• Two phase flow is when both liquid and gas are present in the pipe. This can cause issues with pump performance and requi...read more

Q2. Types of Reactors?
Ans. 
Types of reactors include batch reactors, continuous stirred-tank reactors, plug flow reactors, and fluidized bed reactors.
• Batch reactors: Used for small-scale production and testing.

• Continuous stirred-tank reactors: Ideal for continuous production with uniform mixing.

• Plug flow reactors: Allow for efficient heat transfer and minimal back-mixing.

• Fluidized bed reactors: Suitable for high-temperature reactions and catalys

Q1. Types of Agitators?
Ans. 
Types of agitators include paddle agitators, anchor agitators, turbine agitators, and propeller agitators.
• Paddle agitators are used for low viscosity fluids and gentle mixing.

• Anchor agitators are used for viscous fluids and provide good radial mixing.

• Turbine agitators are used for high viscosity fluids and provide high shear mixing.

• Propeller agitators are used for low viscosity fluids and provide axial flow mixing.

Q2. Gas Drying vs Steam drying?
Ans. 
Gas drying is used to remove moisture from gases, while steam drying is used to remove moisture from solids or liquids.
• Gas drying involves passing a gas stream through a desiccant material to remove moisture, commonly used in natural gas processing.

• Steam drying involves using steam to evaporate moisture from solids or liquids, commonly used in food processing or paper production.

• Gas drying is more suitable for removing...read more

Q1. Heat exchangers and its types?
Ans. 
Heat exchangers are devices used to transfer heat between two or more fluids at different temperatures.
• Types of heat exchangers include shell and tube, plate heat exchangers, and finned tube heat exchangers.

• Shell and tube heat exchangers consist of a shell with tubes running through it, allowing one fluid to flow through the tubes while another flows over the tubes.

• Plate heat exchangers use metal plates to transfer hea...read more
