Paper production
Alfa Laval has a wide range of equipment and many years of process know-how and development to help you increase the efficiency of several processes in your paper production by exchanging existing equipment with our more efficient solutions. In addition to modern separation technologies, our experience and equipment also cover stock preparation, steam and condensate systems, coating, lube oil and wastewater treatment plants.
Modern technologies that increase the efficiency of your paper making processes
- Proven short payback time – profit from extracting high-purity chemicals
- Improved heat recovery and energy efficiency
- Waste minimization
- Increased uptime and production
- Compact designs and small footprints
Alfa Laval has a broad range of tried and tested gasketed-and-welded heat exchangers for heating and cooling in various paper applications. We also have a range of centrifugal separators efficiently clean lube oil from water and particles to ensure a long working life and high uptimes, while our decanter centrifuges help minimize waste for disposal in wastewater treatment plants.
Easy handling of fibrous process fluids
Alfa Laval heat exchangers are optimized to process fluids containing fibers and other solids with ease while providing high thermal efficiency and maximum heat recovery. Other benefits include low installation, operation and maintenance costs as well as complete access to the heat transfer surface to ensure easy cleaning.
Gasketed plate-and-frame heat exchangers
Our Gasketed plate heat exchangers are optimizing heat transfer by large surfaces of corrugated plates drawing heat from one gas or liquid to the other. The high efficiency and an outstanding reliability in a compact design, offers an investment with the most attractive CTO over the product life time. Not to forget the energy saving capabilities and low environmental footprint.
Welded spiral heat exchangers
Alfa Laval spiral heat exchangers are designed to handle the toughest heat transfer challenges. Whether it’s frequent fouling from dirty media, or limitations from pressure drop and floor space, they are the ultimate problem solver for liquid-to-liquid and two-phase duties. The robust, efficient and compact designs keep both installation and maintenance costs extremely low, and they have a proven reputation for almost never fouling up
Compabloc
With over 30,000 units handling tough duties worldwide, Compabloc is the market champion when it comes to heat transfer. Laser-welded construction offers superior reliability in duties with aggressive media and high pressures and temperatures. Compabloc also offers 3-5 times the thermal efficiency of traditional shell-and-tube solutions, with a more compact design that is much easier to install and service.
Lube oil cleaning
All oils contain water, to a certain degree. But when water contaminates the lube oil through leakages and condensation, and the levels rise, this can cause severe problems. For the pulp and paper industry, water is the primary cause of bearing failure.
Discover how SpiralPro works
Alfa Laval spiral heat exchangers are designed to handle the toughest heat transfer challenges. Whether it’s frequent fouling from dirty media, or limitations from pressure drop and floor space, they are the ultimate problem solver for liquid-to-liquid and two-phase duties. For liquid-to-liquid duties, spiral heat exchangers contain two concentric spiral flow channels, one for each fluid. The different media flow counter currently: one fluid enters the centre of the unit and flows towards the periphery, the other enters the unit at the periphery and moves towards the centre. The channels are curved and have a uniform cross section.
