Process Engineer's Tools


Pumps - Piping - Compressors - Heat Exchange - Thermodynamics - Combustion / Furnaces -
Air psychrometrics - Vacuum systems - Data & Diagrams - Calculations tools - Engineer soft skills


My Engineering Tools has been imagined as a website supporting Engineers (and future Engineers !) working in the process industries.

In many aspects, the Process Engineer is the generalist doctor of the factory, he has to answer a wide variety of questions. It thus happens that some fields are less known than others, My Engineering Tools aims at giving a lifeline to the Process Engineers touching those subjects that may not be the core of their works, by offering a starting point.

For each page in the site, My Engineering Tools wishes to make available explanations, formula, examples and if possible Excel calculation tools.
