What is the level of process knowledge? Process chemistry and physics

Reaction chemistry thermodynamics heat and mass transferReaction chemistry, thermodynamics, heat and mass transfer

Mass and energy balances (design and transient conditions) Process safety O ti E l Operating Envelope External constraints Materials of construction Personnel

Is the basis of design consistent with program objectives?Which process components are first of a kind?

Does the process design account for technical and programmatic uncertainties?
