What operational changes are required when converting a plant from cutback bitumen to emulsion bitumen production?

Conversion requires adding a water phase system with heating, dosing, and pH control, installing a colloid mill, and replacing solvent oriented piping with corrosion compatible materials where acids are used. Operators must adopt new startup sequences focused on temperature balance and shear stability. Tank cleaning procedures change because emulsions can leave stubborn residues. Quality control expands to include pH, particle charge, stability, and residue tests. Safety focus shifts from solvents to acid handling and prevention of microbial growth in water systems.
