Ingenero Technologies Technical Lead Interview Questions and Answers

Porosity is the measure of empty spaces in a material, often used in geology and engineering.

• Porosity is the ratio of void spaces to total volume in a material.

• It is expressed as a percentage.

• Porosity is important in fields like geology for assessing rock formations and in engineering for determining the strength of materials.

• Examples of porous materials include sponges, pumice stones, and aerogels.

Permeability is the property of a material that allows fluids or gases to pass through it.

• Permeability is a measure of how easily a substance can pass through a material.

• It is often used in geology to describe how easily fluids can flow through rocks or soil.

• Permeability can be affected by factors such as pore size, connectivity, and fluid viscosity.

• Materials like sandstone have high permeability, while materials like

I am passionate about helping others and believe this job will allow me to make a positive impact in the community.

Oil shale is a rock containing kerogen that can be converted into shale oil through a process called retorting.

• Oil shale is a sedimentary rock containing kerogen, a precursor to oil.

• Shale oil is the liquid hydrocarbons extracted from oil shale through a process called retorting.

• Oil shale deposits are found in various countries like the United States, Estonia, and China.

• Shale oil production has increased in recent years

Velocity change affects flow in a venturimeter.

• As velocity increases, pressure decreases and vice versa.

• Flow rate is directly proportional to the square root of pressure difference.

• Venturimeter is used to measure flow rate in pipes.

• Flow rate can be calculated using Bernoulli's equation.

PFR is better for zero order reaction as it maintains constant concentration throughout the reactor.

• PFR maintains constant concentration throughout the reactor

• CSTR may result in concentration gradients

• PFR is more efficient for zero order reactions

• CSTR may be more suitable for reactions with changing rate constants

The overall refinery setup typically includes crude oil distillation units, catalytic cracking units, hydrotreating units, and various other processing units.

• Crude oil distillation units separate crude oil into different fractions based on boiling points

• Catalytic cracking units break down heavy hydrocarbons into lighter products like gasoline and diesel

• Hydrotreating units remove impurities like sulfur from products to ...read more
