Biocon Limited Production Interview Questions and Answers

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...read more

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.

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.

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.

• Casc...read more

The help of the resin packed in a column can be found using the formula: H = L / (1 - ε)

• Calculate the height of the resin packed in a column using the formula H = L / (1 - ε)

• H is the height of the resin packed in the column

• L is the length of the column

• ε is the void fraction of the resin bed

• The formula helps in determining the effective height of the resin bed in the column
