Increasing efficiency at mechanical
pulp mills

Every pulp mill is unique, and the challenges facing mill operators are many. Mill operators must find ways to remain profitable despite increasing labour, chemical and energy costs while ensuring mill productivity.

Improving energy efficiency at mechanal pulp mills

Energy accounts for up to 30 percent of all mill production costs. So it comes as no surprise that energy-intensive mills must focus on energy efficiency. Alfa Laval offers a broad range of solutions to optimize the use of energy at pulp mills. The heat recovered from cooling filtrate from thickeners, for instance, can be resued to heat circulation water for paper machines. Solutions like these improve quality, productivity and reliability while delivering savings to the bottom line.

Easy handling of fibrous process fluids

Alfa Laval heat transfer, separation and fluids handling equipment, such as our WideGap and spiral heat exchangers, handles highly viscous process fluids containing fibres 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 both sides of the plates to ensure easy yet thorough cleaning, should this prove necessary.

Maximizing electricity production in power boilers

Maximizing electricity production is a critical factor to mill productivity and profitability. To ensure zero downtime, Alfa Laval provides exceptionally reliable and efficient equipment, including state-of-the-art power and recovery boiler technology to help generate the energy required. Our compact heat exchangers, for instance, provide a space-saving, reliable and resilient alternative to bulky shell-and-tubes and enjoy solid reputation as the workhorse of pulp mill power plants.

Efficient wastewater treatment

Processing large volumes of wastewater and residual sludge waste poses challenges for many mills. Alfa Laval offers a complete spectrum of wastewater equipment to help minimize environmental impact and maximize energy savings. Water line applications include MBR, SBR, heat exchangers and tertiary filtration using membranes or cloth media. For sludge line applications, Alfa Laval offers a full range of equipment for thickening and dewatering.
