👤 About Us

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.

🎓 MTech — Chemical Engineering
🏭 7+ years industrial process plant experience
💻 Engineering software developer — Python / Streamlit
📹 YouTube educator — GATE Chemical Engineering
