Akamai Technologies Interview Questions and Answers
Q1. How you decide how much kg of steam is required for different Chemicals?
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
Q2. What is mean by vaccum pressure
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
Q3. Difference between simple and fractanation distillation..
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
Q4. What is mean by collection wall
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
Q5. Pumps characteristics curves.
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
Q6. What is mean by circulation
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
Q7. What is mean by steam get
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
Q8. What is mean by heating
Heating is the process of increasing the temperature of a substance or object.
Heating involves the transfer of energy to a substance, causing its molecules to move faster and increase in temperature.
It can be achieved through various methods such as conduction, convection, or radiation.
Examples of heating include boiling water on a stove, using a microwave to warm food, or using a heater to warm a room.
