Alfa Laval Compabloc saves energy in ammonium nitrate production
When a fertilizer manufacturer in Slovakia, built their ammonium nitrate evaporation system in 1999, there was one criteria above all others for the design. It had to be efficient. With that in mind, they discovered that Alfa Laval Compabloc heat exchangers could help keep both their evaporator cost – and their energy bill – down.DATE 2022-01-27
Their bottom line just got a lot hotter
At the plant, two Compablocs are used to save no less than 5MW of energy by means of reduced steam consumption in the second effect evaporator.
By using Compabloc heat exchangers for preheating incoming 80% ammonium nitrate with 95% concentrated ammonium nitrate, they were able to save large amounts of energy.
In fact, without the Compablocs it would not be possible to concentrate the ammonium nitrate without a substantial increase of the evaporator size and much higher steam consumption.
The Compabloc welded heat exchanger is probably the most compact and efficient heavy-duty heat exchanger in the world.
- 5 megawatts of steam energy saved
- Possible to concentrate the ammonium nitrate without a substantial increase of the evaporator size and without significantly higher steam consumption.
When they built their ammonium nitrate plant in 1999, the company was looking for the optimal solution in terms of a compact, robust and energy efficient solution.
The Compabloc welded plate heat exchanger from Alfa Laval is suitable for operation in chemically aggressive environments and for handling high-temperature fluids.
With accessibility to all heat transfer channels, maintenance is straightforward and efficient.
