Infraplan Engineering Services Interview Questions and Answers

Autoclave is a device used for sterilization by subjecting objects to high-pressure steam.

• Autoclaves are commonly used in medical and laboratory settings.

• They work by using high-pressure steam to kill bacteria, viruses, and other microorganisms.

• Autoclaves can sterilize a variety of materials, including surgical instruments, glassware, and textiles.

• The sterilization process typically takes around 15-20 minutes.

• Autoclaves have safety features to prevent explosions or other acci...read more

A saccharification reactor is used in the production of biofuels and converts starch into sugars.

• It is a vessel where starch is mixed with enzymes to break down the starch into simple sugars.

• The simple sugars are then fermented to produce ethanol or other biofuels.

• The reactor is typically operated at high temperatures and pressures to optimize the saccharification process.

• Examples of enzymes used in the process include alpha-amylase and glucoamylase.

ION Exchange is a process of removing ions from a solution and replacing them with other ions of similar charge.

• It is commonly used in water treatment to remove impurities.

• It is also used in the production of pharmaceuticals and electronics.

• The process involves passing the solution through a resin bed that contains exchangeable ions.

• The resin can be regenerated by washing it with a solution of the desired ions.

A reactor is a vessel or device used for chemical reactions, nuclear reactions, or power generation.

• Reactors are used in various industries such as chemical, pharmaceutical, and nuclear.

• Chemical reactors are used to produce chemicals by mixing reactants together.

• Nuclear reactors are used to generate electricity by harnessing the energy released from nuclear reactions.

• Reactor design depends on the type of reaction, reactants, and desired outcome.

• Examples of reactors include ba...read more

Cooling tower is a heat rejection device that removes waste heat from the water-cooled system.

• Water is circulated through the tower and sprayed over the fill material.

• Air is drawn through the tower by the fan, which cools the water by evaporation.

• The cooled water is then returned to the system.

• The tower can be of different types such as natural draft, mechanical draft, crossflow, counterflow, etc.
