Paper Machine Energy Conservation

The paper machine area is a major energy consumer in most pulp and paper mills. The high cost of energy makes it important to implement energy management and conservation measures. Paper machine energy consumption represents 50-70% of purchased energy for an otherwise efficient integrated mill. If paper machines are inefficient in use of energy, the mill will be uncompetitive. Reductions in energy consumption reduce operating costs and increase profitability. Reducing paper machine energy consumption requires attention to details in design, operation, maintenance, and control of nearly all aspects of the papermaking process. This TIP discusses guidelines for monitoring, benchmarking, and optimizing energy-intensive unit operations to reduce paper machine energy consumption.
