This knowledge can be incorporated into production processes to adjust the rate of fluid flow and reduce crystal accumulation.
Based on this new insight into why and how quickly crystals accumulate, Isaac Appelquist Løge will create a model that can be used to plan the most appropriate cleaning schedule.
Valuable knowledge for many industries
Crystal accumulation poses a problem not only in heat exchangers but also in other industries that pump liquids through pipes, which include everything from the food industry, CO2 transport and storage, and geothermal energy to the oil and gas industry.
“If the diameter of the pipes becomes smaller as crystals accumulate in the pipes, you need more energy to force the same amount of liquid through,” explains Isaac Appelquist Løge.
The pipes must therefore be cleaned before the pressure loss becomes too great, but not unnecessarily often, as cleaning is expensive. On an oil rig, the challenge is particularly great, as production must be stopped in the meantime, and manpower and materials must be transported offshore.
The new knowledge can also be used in these industries to calculate the optimal cleaning routines.
