TCS Interview Questions and Answers

Enzymes play a crucial role in the production process. Some commonly used enzymes are amylase, protease, cellulase, and lipase.

• Amylase is used to break down starch into simple sugars.

• Protease is used to break down proteins into amino acids.

• Cellulase is used to break down cellulose into glucose.

• Lipase is used to break down fats into fatty acids and glycerol.

• Enzymes are used in various industries such as food, pharmaceuticals, and textiles.

RO water is purified water while process water is used in industrial processes.

• RO water is purified through reverse osmosis process which removes impurities and minerals.

• Process water is used in industrial processes such as cooling, heating, and cleaning.

• RO water is safe for drinking while process water is not.

• RO water has a low conductivity level while process water has a high conductivity level.

• RO water is used in households while process water is used in industries.

The fermentation formula of ethanol is C6H12O6 → 2 C2H5OH + 2 CO2.

• Ethanol is produced by the fermentation of sugars by yeast or bacteria.

• The chemical equation for the fermentation of glucose to ethanol is C6H12O6 → 2 C2H5OH + 2 CO2.

• The process requires anaerobic conditions and a temperature range of 20-30°C.

• The fermentation process can take anywhere from a few hours to several days depending on the conditions.

• The resulting ethanol can be used as a fuel, solvent, or in alcohol...read more

Water treatment process involves physical, chemical and biological processes to remove impurities and make it safe for consumption.

• Physical processes like sedimentation and filtration remove large particles and debris.

• Chemical processes like coagulation and disinfection remove smaller particles and microorganisms.

• Biological processes like activated sludge and biofiltration use microorganisms to break down organic matter.

• Chemicals used in water treatment include chlorine, alum...read more

• Quality check of mixture

• Processing and manufacturing

• Quality check of final product

• Packaging and labeling

• Storage and distribution

The flash point of Ethanol is 16.6°C.

• Flash point is the temperature at which a liquid gives off enough vapor to ignite in air.

• Ethanol is a highly flammable liquid with a low flash point.

• The flash point of ethanol is 16.6°C or 61.9°F.

• This means that ethanol can easily catch fire at room temperature.

Process water is treated through reverse osmosis (RO) to remove impurities and produce RO water.

• Process water is first passed through a pre-treatment system to remove large particles and impurities.

• The pre-treated water is then pumped through a series of RO membranes that filter out dissolved solids and contaminants.

• The resulting RO water is then stored in a tank for use in production processes.

• Regular maintenance and cleaning of the RO system is necessary to ensure optimal p...read more
