Energy Optimisation

Anssum’s Energy Optimisation solution is a comprehensive, mill-wide advanced process control strategy specifically designed for the pulp and paper industry, aiming to maximise energy utilisation and minimise waste. Our innovative solution can be implemented as either a Heat Exchanger Efficiency Optimisation or a Heat Exchanger Network Dynamic Optimisation, both focused on improving overall efficiency and reducing energy costs.

This advanced optimisation solution ensures maximum heat transfer efficiency through UA (Overall Heat Transfer Coefficient) optimisation, balanced heat distribution via heat load control, and maximises net energy transfer while maintaining operational constraints. Compliance with limit constraints is carefully observed to prevent equipment damage and maintain safe operating conditions. By optimising heat transfer, reducing energy consumption, enhancing equipment performance, and minimising environmental impact, our Heat and Energy Optimisation solution not only improves the overall efficiency of your operation but also contributes to sustainable practices, reducing operational costs, and boosting profitability.
