Built by an Engineer.
For Engineers.
ChemicalEngineers.in was created by a chemical engineer with an MTech degree and over 7 years of hands-on experience in process plants — working directly with multi-effect evaporators, distillation columns, reactors, and utility systems.
Every tool on this site is built with the same rigour you would apply in a real engineering design. No shortcuts, no unvalidated approximations — just methods that work in the plant.
