Sulzer’s EvapCare™-F technology boosts efficiency and product integrity in distillation plants

Used in combination with distillation or as a standalone unit, falling film evaporators are essential for handling heat-sensitive substances in sectors such as fine chemicals, pharmaceuticals, and bio-based materials. However, as demand for more sustainable operations and products increases, existing evaporation systems often fall short, especially in terms of energy recovery, process stability, and product degradation.

The EvapCare-F technology meets these challenges head-on. Developed to support both traditional and electrified distillation systems, including Sulzer’s own VoltaSplit™, the unit uses an advanced liquid distribution system to form a stable, uniform film across every evaporator tube. This innovation enables faster evaporation with minimal thermal stress, ensuring better product quality and higher yields, even under vacuum.

Maximizing value through efficiency

The novel technology offers impressive performance benefits, including up to 50% fewer production interruptions thanks to reduced fouling and scaling, and over 40% lower heat consumption in multi-effect setups. It can also offer shorter residence times and superior heat transfer, reducing the risk of product degradation.

“With EvapCare, our customers can modernize their separation processes for today’s sustainability and performance demands,” said Ilja Mikenberg, Sulzer’s Global Head of Process Solutions. “It’s a versatile, future-ready technology that combines decades of Sulzer experience with innovative design.”

Built for plug-and-play integration into new or existing plants, and suitable for large-scale operations, particularly in vacuum applications, EvapCare-F is engineered to meet the needs of demanding applications across industries. Whether used in petrochemicals, pharmaceuticals, flavors and fragrances, or wastewater treatment, it helps facilities enhance performance, reduce energy consumption, and maintain exceptional product quality.
