Akamai Technologies Interview Questions and Answers

The amount of steam required for different chemicals is determined by their heat of vaporization and the desired process temperature.

• Calculate the heat of vaporization for the chemical

• Determine the desired process temperature

• Use steam tables to find the amount of steam required

• Consider any heat losses in the system

• Adjust for any safety factors

Vacuum pressure is the pressure below atmospheric pressure.

• Vacuum pressure is the pressure below atmospheric pressure.

• It is measured in units such as torr, pascal, or bar.

• Vacuum pressure is commonly used in industries like chemical plants, manufacturing, and research laboratories.

• Examples of vacuum pressure applications include distillation, evaporation, and vacuum drying.

• Vacuum pressure is created by removing air or gas from a closed system, resulting in a lower pressure env...read more

Simple distillation separates two liquids with different boiling points, while fractional distillation separates multiple components of a mixture.

• Simple distillation is used when the boiling points of the two liquids are significantly different.

• Fractional distillation is used when the boiling points of the components are closer together.

• Fractional distillation uses a fractionating column to separate the components based on their boiling points.

• Simple distillation is a one-ste...read more

A collection wall is a barrier used to collect and contain materials or substances in a chemical plant.

• A collection wall is typically made of materials that are resistant to the substances being collected, such as stainless steel or concrete.

• It is designed to prevent the spread of hazardous materials in case of leaks or spills.

• Collection walls are commonly used in areas where chemicals are stored or processed, such as storage tanks or reaction vessels.

• They can also be used to...read more

Pump characteristic curves show the relationship between flow rate, head, and power consumption.

• Pump curves are used to select the appropriate pump for a given application.

• The shape of the curve depends on the type of pump and impeller design.

• The point where the pump curve intersects the system curve determines the operating point.

• Operating a pump away from its best efficiency point can result in increased energy consumption and reduced pump life.

• Pump curves can also be used ...read more

Circulation refers to the movement or flow of a substance or fluid within a system or organism.

• Circulation can refer to the movement of blood through the circulatory system in the human body.

• In a chemical plant, circulation can refer to the movement of fluids or gases through pipes or vessels.

• Circulation is important for maintaining proper distribution and transport of substances within a system.

• Examples of circulation include the circulation of air in HVAC systems or the cir...read more

Steam get refers to the process of obtaining steam in a chemical plant.

• Steam get involves generating steam through the use of boilers or other heat sources.

• The steam is typically used for various purposes such as heating, power generation, or as a reactant in chemical reactions.

• Steam get may involve treating the feedwater to remove impurities and ensure the quality of the steam.

• Steam get is an essential part of the operation of a chemical plant as it provides the necessary en...read more
