Q2. Difference between CSTR and PFR, Pumps ,Heat Exchanger.
Ans. 
CSTR and PFR are types of reactors, pumps are used to move fluids, heat exchangers transfer heat between fluids.
• CSTR (Continuous Stirred Tank Reactor) has a constant volume and operates under steady-state conditions.

• PFR (Plug Flow Reactor) has a varying volume and operates under unsteady-state conditions.

• Pumps are mechanical devices used to move fluids from one place to another, like centrifugal pumps or positive displ...read more

Q3. What is cracking
Ans. 
Cracking is a process in which complex hydrocarbon molecules are broken down into simpler molecules.
• Cracking is a refining process used to convert large hydrocarbon molecules into smaller, more valuable ones.

• It is done by breaking the carbon-carbon bonds in the molecules.

• Examples include catalytic cracking and steam cracking.

Q4. What is Reforming
Ans. 
Reforming is a process used in the petroleum industry to convert low-octane naphtha into high-octane gasoline.
• Reforming involves rearranging the molecular structure of hydrocarbons to increase their octane rating.

• It is typically done using a catalyst at high temperatures and pressures.

• The process can also produce hydrogen gas as a byproduct.

• Reforming is an important step in the production of gasoline and other fuels in...read more

Q5. What is range and approach of cooling tower
Ans. 
The range of a cooling tower refers to the maximum distance at which it can effectively cool air, while the approach is the temperature difference between the cooled water and the entering air.
• Range of a cooling tower is typically around 5-20 degrees Fahrenheit

• Approach of a cooling tower is usually around 8-15 degrees Fahrenheit

• The range and approach of a cooling tower can vary based on factors such as design, size, an

Q1. What is Heat of formation
Ans. 
Heat of formation is the energy released or absorbed when one mole of a compound is formed from its elements in their standard states.
• Heat of formation is also known as standard enthalpy of formation.

• It is typically measured in units of kJ/mol.

• Negative heat of formation indicates exothermic reaction, while positive heat of formation indicates endothermic reaction.

• For example, the heat of formation of water (H2O) is -28

Q2. What is heat of reaction
Ans. 
Heat of reaction is the amount of heat released or absorbed during a chemical reaction.
• Heat of reaction can be exothermic (heat released) or endothermic (heat absorbed).

• It is typically measured in units of joules or calories.

• Examples include combustion reactions releasing heat and photosynthesis reactions absorbing heat.

1st aptitude followed by psychometric test .

Q1. 1. How you will select a heat exchanger for different type of fluids.
Ans. 
The selection of a heat exchanger for different fluids depends on factors such as fluid properties, flow rates, and heat transfer requirements.
• Identify the properties of the fluids such as viscosity, density, and thermal conductivity.

• Determine the flow rates and pressure drops of the fluids.

• Select the appropriate type of heat exchanger such as shell and tube, plate and frame, or spiral.

• Consider the heat transfer requir...read more

Q2. What Is reflux ratio.
Ans. 
Reflux ratio is the ratio of the amount of liquid refluxed to the amount of liquid that is being distilled.
• It is an important parameter in distillation processes.

• It helps in determining the efficiency of the distillation column.

• A high reflux ratio results in a higher purity of the distillate.

• Reflux ratio can be adjusted to optimize the distillation process.

• It is calculated as the ratio of the reflux flow rate to the di
