• Market forces:
— Where products are seasonal (e.g., fertilizers).
— Short product lifetime (e.g., organic pigments).
• Operational problems:
— Long reaction times (i.e., when chemical reactions are slow).
— Handling slurries at low flowrates.
— Rapidly fouling materials (e.g., materials foul equipment so
rapidly that shutdown and frequent cleaning are required).
