Interview Questions and Answers

Increase vacuum and temperature to recover any remaining chemical.

• Increase vacuum to lower the boiling point of the chemical.

• Raise temperature to increase the vapor pressure of the chemical.

• Use a condenser to collect the vapor and recover the chemical.

• Repeat the process until no more chemical can be recovered.

• Dispose of any remaining waste safely and responsibly.

Safety in IBC in charge in reactor involves various measures such as IBC in property arthing plate, vent, interlock, PPE, etc.

• IBC in property arthing plate is used to prevent static electricity buildup and discharge.

• Ventilation systems are installed to ensure proper air circulation and prevent the accumulation of hazardous gases.

• Interlock systems are implemented to ensure safe operation and prevent unauthorized access.

• Personal Protective Equipment (PPE) such as gloves, goggle...read more

Reflux is used in distillation column for temperature and purity maintenance in product.

• Reflux helps in maintaining a constant temperature in the distillation column.

• It also helps in achieving a higher purity of the product by preventing the vaporized product from escaping the column.

• Reflux is achieved by condensing some of the vaporized product and returning it back to the column.

• This process helps in achieving a more efficient separation of the components in the mixture bei...read more

DCS stands for Distributed Control System and includes open loop, closed loop, and cascade loop control strategies.

• DCS is a computerized control system used to manage and automate industrial processes.

• Open loop control is a control strategy where the output is not measured or compared to the input.

• Closed loop control is a control strategy where the output is measured and compared to the input to adjust the process.

• Cascade loop control is a control strategy where the output of...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 is used to separate components with closer boiling points...read more
