Prasol Chemicals Interview Questions, Process, and Tips

ETP process is a method of treating wastewater to remove pollutants before releasing it into the environment.

• Wastewater is collected and screened to remove large debris.

• The water is then treated with chemicals to remove smaller particles and pollutants.

• Biological processes are used to break down organic matter.

• The water is disinfected to kill any remaining bacteria or viruses.

• The treated water is then released into the...read more

The required norms of pollution control for MPCB include monitoring and regulating air, water, and noise pollution.

• MPCB sets emission standards for industries and monitors their compliance

• Industries are required to obtain consent to operate from MPCB

• MPCB conducts regular inspections and takes legal action against violators

• MPCB also regulates the disposal of hazardous waste

• Examples of MPCB regulations include the Mahara...read more

Alcohols are organic compounds with hydroxyl (-OH) functional group. Atomic weight varies depending on the type of alcohol.

• Alcohols can be classified as primary, secondary, or tertiary based on the number of carbon atoms attached to the carbon atom with the hydroxyl group.

• Methanol, ethanol, propanol, butanol, pentanol, and hexanol are some common alcohols.

• The atomic weight of alcohols varies depending on the number of ...read more

A boiler is a closed vessel used to generate steam or hot water for heating or power generation.

• Boilers can be fueled by various sources such as natural gas, oil, coal, or biomass.

• Boilers can be classified into different types such as fire-tube, water-tube, and electric boilers.

• Boilers require regular maintenance to ensure efficient and safe operation.

• Boilers are commonly used in industries such as power generation, ch...read more

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

Chemical processes involve the transformation of raw materials into useful products using chemical reactions.

• Examples of chemical processes include distillation, fermentation, and polymerization.

• Valves are commonly used in chemical processes to control the flow of fluids.

• pH is a measure of the acidity or basicity of a solution.

• Types of pumps used in chemical processes include centrifugal pumps, positive displacement pu

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
