Caustic soda evaporation
Alfa Laval provides complete, compact and energy-efficient caustic soda and caustic potash evaporation systems. The special corrosion-resistant design, allied to low operating temperatures, reduces corrosion rates and translates into longer equipment lifetime and a higher level of plant reliability. Reduced liquid hold-up volumes also speed up startup and shutdown.
Flexible, energy-efficient caustic evaporation systems
- Available in 1 to 4-effect configuration, and up to 2,000 ton/day
- Capacity easily upgradable thanks to modular design
- Significantly lower installation height
- Less power and steam consumption than traditional shell-and-tube solutions
- Available in standard 32-50% concentration, and customized configurations up to 75% concentration
Simple installation, operation and expansion
The compact design means easy maintenance and operation. Capacity can be increased simply by adding more cassettes – a major benefit compared with traditional shell-and-tube evaporators.
Optimize process with triple- or quadruple-effect systems
With an Alfa Laval triple-effect evaporator system you can generally look forward to the best cost:performance ratio. In areas where steam and electricity costs are low, our double-effect system may offer lower installation costs and good operating economy. And where steam cost is high, opting for a quadruple-effect evaporator system may be the answer – the significant savings in steam and fast payback time may justify the additional investment.
Upgrade your existing plant?
We can help upgrade your existing plant to improve performance and capacity or remove bottlenecks. Our efficient pre-heaters or high performance gaskets are just two examples of how we can help you get more from your plant. Contact us for a plant audit by process specialists who can assess and propose required modifications.
