Why HB Process
An engineering platform, not just notes
Real tools, practical writing, and problems worked from first principles, all tied together in one place.
Real engineering tools
Line hydraulics, heat exchanger and control valve sizing, and P&ID drawing, the same methods used on real plants.
In-depth articles
Practical, well-written process engineering guides that teach the reasoning, not just the result.
Engineering toolkit
The tools industry actually runs on
Not just theory. Training and walkthroughs built around the simulation and design software used in real plants and engineering companies.
