Paper production is the result of a complex process requiring huge quantity of water but also some energy.
The key issue for operators is therefore energy efficiency and the recovery of effluents, filtrates and other by-products.
Papermaking is divided into 8 steps:
The Weplex® exchanger will provide a set of innovative solutions for processing the by-products from this production process. It will intervene in the energy recovery of these charged fluids. Among them:
- White water: which the Weplex® exchanger can heat or cool to reach the set temperature.
- The black liquor heat (from the cooking of the fibers) can be recovered.
- The filtrate.
- The effluents from which we will recover the calories to optimize paper mill production costs. Furthermore, it can be used to respect the maximum temperature of 30 ° C of discharge of treated water, in a natural environment.
In addition, the Weplex® exchanger can also be used to heat or cool all types of fluids (water, oil, gas, fuel oil, etc.)
The Weplex® exchanger: an exchanger suitable for paper factory.
The large channels and welded plates Weplex® heat exchanger is designed to to take into account the different constraints of pulp and paper industry.
Indeed, its innovative and patented design guarantees a significant reduction in production shutdowns.
The decrease in the frequency of those is about a monthly preventive cleaning for a Weplex® exchanger, versus an inescapable weekly cleaning for a conventional exchanger.
The duration of those production shutdowns is also divided by 3 due to the easy opening of the device and its large channels allowing rapid cleaning.
With a higher exchange coefficient compared to a traditional equipment as well as Duplex materials, the Weplex® exchanger is less energy-consuming and more robust over time.
