Evaporator Operational & Cleaning Optimisation

At Anssum, we understand the challenges faced by pulp and paper mills in optimising their evaporator operations and cleaning processes. That’s why we’ve developed our advanced Evaporator Operational & Cleaning Optimisation solution. By leveraging sophisticated algorithms and modeling techniques, we’re able to gain a thorough understanding of your evaporator behavior over a campaign life, which allows us to develop a customised, optimal operational and cleaning strategy.

Our solution takes into account all relevant parameters, such as temperatures, pressures, recirculation rates, compressor duties, and previous washing and digester performance, etc. By constantly monitoring and adjusting the operational and cleaning processes, we’re able to maintain optimal heat transfer coefficient throughout the campaign life, under all plant operating conditions, avoiding the build-up of excessive fouling, sintering, and plugging. Our solution is suitable for various evaporator (including Mechanical Vapor Recompression and Multiple Effect) and effect (horisontal/vertical tube and falling film) applications.

The result is increased efficiency, reduced costs, and minimised environmental impact for your mill.

Case study

At Anssum, we’re committed to helping pulp and paper mills optimise their operations and improve their performance. In a recent case study, we worked with a mill to implement our advanced Evaporator Operational & Cleaning Optimisation solution.

The mill was facing challenges with excessive fouling, sintering, and plugging, leading to reduced efficiency and increased costs. Our team of experts worked closely with the mill to develop a customised, optimal operational and cleaning strategy, based on a thorough understanding of the mill’s specific requirements.

Is this solution for your evaporator?

Our Evaporator Operational and Cleaning Optimisation is the solution you need for your Evaporators if:

  • The steam economy is below desired or benchmark levels
  • The liquor solids content needs to increase
  • The solids content fluctuates more than (insert a percentage, make sure it is a small amount)
  • Compressor electricity costs needs to be reduced.
  • Mean time between cleaning shutdowns needs to be increased
  • Fouling in certain stages leading to a reduction in performance
  • Plant operates under varying conditions (wood quality and species)
  • Excessive equipment wear and tear due to washing

Our solution is specifically optimised for each mill’s objectives, constraints, and hardware setup. No modifications to the evaporator or additional control hardware or software are required. The solution does not require the plant to be shut down, and because no modifications are necessary, the return on investment is typically less than 3 months.
