The SQM finishing plants have a unit operation for drying salts. To carry out this process, a rotary dryer is used which requires heating the salts to 500°C. Once the process is finished, the product is cooled before shipping to the next phase of the process, resulting in the dissipation of heat at 130°C through the industrial chimneys.
We are looking for a technological solution that allows capturing the residual heat released during this process, taking advantage of the temperature difference for reuseing it as energy in the process. In this way, we hope to reduce energy consumption and, therefore, the use of fossil fuels.
How will we evaluate your solution?
It is expected to achieve a reduction of at least 30% in the energy required for the operation of the dryer.
