Chemical Engineering roadmap

Mass & heat transfer, reaction engineering, process control and plant safety.

Start with Chemical Fundamentals, follow the steps in order, then build a project, prepare for interviews and earn your certificate.

Foundations

  1. Chemical Fundamentals — Moles, balances, energy and equilibrium — the language of process engineering. The core toolkit every chemical engineer uses daily: mole concepts and stoichiometry, material balances with recycle, energy balances and heats of reaction, and phase and reaction thermodynamics.
  2. Fluid Mechanics — Moving liquids and gases through pipes, pumps and compressors. Fluid behaviour for process plants: properties and viscosity, flow regimes and the Reynolds number, pumps and compressors, and pressure drop in piping systems.
  3. Heat Transfer — Conduction, convection, radiation and exchanger design. How heat moves in process equipment: conduction through walls and insulation, convection in flowing fluids, radiation in furnaces, and heat-exchanger sizing and rating.

Core skills

  1. Mass Transfer — Separating mixtures — the heart of chemical processing. Most of a chemical plant's cost is in separations. Learn molecular diffusion and mass-transfer coefficients, then the major separation operations: distillation, absorption, liquid–liquid extraction, adsorption, drying and humidification — with stage and sizing calculations.
  2. Reaction Engineering — Rates, catalysts and reactors — where chemicals are made. The heart of every chemical plant is its reactor. Learn reaction kinetics and the Arrhenius law, catalysis, the general reactor design equations, and the three ideal reactors — CSTR, plug-flow and batch — with sizing, comparison and heat-management calculations.
  3. Process Control — Measuring and steering plants — sensors to control rooms. How chemical plants are kept on target: process sensors, controllers and control valves, PID control, instrumentation and P&IDs, and the DCS and SCADA systems that run plants and pipelines.

Advanced

  1. Process Equipment — Specifying the hardware that makes a plant. From process calculations to real equipment: boilers, shell-and-tube heat exchangers, reactor vessels and agitators, distillation column hardware, and the selection and specification of pumps and compressors — with sizing rules engineers use on datasheets.
  2. Process Safety — Keeping hazards inside the pipes. How chemical engineers prevent disasters: HAZOP studies, quantitative risk analysis and LOPA, fire hazards and flammability, explosions and blast effects, and the handling of toxic and hazardous materials — with the consequence models used in real safety studies.
  3. Process Simulation Software — Digital twins of chemical plants. The software chemical engineers use every day: Aspen Plus for steady-state flowsheets and thermodynamics, MATLAB for modelling reactors and control with ODEs, and COMSOL for multiphysics (flow, heat, mass transfer and reaction in real geometry) — with working scripts and workflows.
