Advanced hydrogel-based systems for efficient water recovery in steel production
This innovative hydrogel technology offers a highly efficient solution for water recovery in the steel industry, capable of absorbing 8 kg of water per 1 kg of gel. It can be integrated into existing systems, enhancing water recovery without major infrastructure changes.
Overview
Advanced hydrogel-based systems present a transformative solution for water recovery in the steel industry. These hygroscopic hydrogels can absorb 100-1000 times their dry weight in water, making them exceptionally efficient in capturing water vapor and steam. Tailored for the demanding thermal conditions of steel production, these hydrogels can enhance water recovery processes significantly. They are designed to be retrofitted into existing heat exchangers, providing a plug-and-play solution that improves water recovery without the need for substantial infrastructure modifications.
Technical specifications
Key features:
- Ability to absorb over 8 kg of water per 1 kg of dry gel at 70% relative humidity (RH) and 25°C.
- High efficiency across a broad temperature range, suitable for extreme thermal conditions in steel production.
- Fully regenerable at low temperatures (<58°C), ensuring sustainable and energy-efficient reuse.
- Customizable compositions to optimize absorption efficiency and durability for specific processes.
- Applicable as a retrofit solution, easily integrating into existing systems to enhance performance.
