How does emulsion type selection impact plant configuration and operating cost for bitumen emulsions production?
Emulsion type strongly influences plant complexity and operating cost. Cationic emulsions require acid dosing systems and corrosion-resistant components, increasing CAPEX and OPEX. Polymer-modified emulsions need additional heating, mixing, and sometimes pre-blending units. Slow-setting emulsions may require longer milling times and higher emulsifier consumption. Selecting too many emulsion grades for one plant increases changeover losses, cleaning time, and inventory complexity.
