AbstractToday, the most important factors in the evolution of people's living standards are the development of industrialization and production capabilities. In the industrial sector, fossil-based energy sources are widely used and cause production costs to increase and competitiveness to decline, especially in countries that are dependent on energy supply. In addition to this, the use of energy as efficiently as possible and the recycling of waste energy can reduce both costs and adverse environmental problems. In the study, the use of the waste heat from the basic oxygen converter process used in the iron and steel industry has been examined again to meet the demand for demineralized water and to convert the overproduced water into a financial resource and to avoid adverse environmental effects. For this purpose, a demineralized water production system that operates on the basis of a humidification-dehumidification method compatible with the amount of waste heat, whose investment costs are more advantageous than other methods, is designed and the production capacity is calculated. It has been determined that the obtained data is at a very high level of demineralized water producing potential of the designed system and that this recycling application can be funded considerably.
