Gujarat Fluorochemicals Engineer Trainee Interview Questions and Answers

Q1. Type of fluid and incomprehensible fluid type
Ans. 
The question is likely asking about the different types of fluids and possibly about non-Newtonian fluids.
• Different types of fluids include Newtonian fluids (water, air) and non-Newtonian fluids (ketchup, blood)

• Newtonian fluids have constant viscosity regardless of shear rate, while non-Newtonian fluids change viscosity with shear rate

• Non-Newtonian fluids can be further classified as shear-thinning (decreasing viscosit...read more

Q2. What is pump and it's type
Ans. 
A pump is a mechanical device used to move fluids from one place to another. There are different types of pumps based on their working principle and application.
• Pumps can be classified into two main types: positive displacement pumps and centrifugal pumps.

• Positive displacement pumps move fluid by trapping a fixed amount and forcing it into a discharge pipe. Examples include gear pumps and piston pumps.

• Centrifugal pumps...read more

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
