Chemical Engineering

AI-proof? Running and optimizing physical plants requires on-site engineering judgment AI can't replace, though process simulation is AI-assisted.

• ▸Check overnight plant data each morning — flows, temperatures, pressures — and chase anything drifting off spec.
• ▸Build and tune process simulations in Aspen HYSYS or Aspen Plus to size equipment or test a design change.
• ▸Walk the unit with operators to troubleshoot a fouled exchanger, off-spec batch, or misbehaving pump.
• ▸Run HAZOP and process-safety reviews — documenting what can go wrong and how the design prevents it.
• ▸Write technical reports and management-of-change paperwork before any modification goes live.
