Optimal energy management in pulp and paper mills

Drivers, Barriers, and Success Factors for Improving Energy Management in the Pulp and Paper Industry

“…In addition, modelling was utilized for minimizing energy costs, as described by Sarimveis et al [76] and Marshman et al [15]. Briefly, Sarimveis et al [76] studied the utilization of mathematical programming tools to find the optimal EnM of the power plant in PPI mills, aiming to cost-effectively fulfil the total need of a plant for energy and steam.…”

“…Briefly, Sarimveis et al [76] studied the utilization of mathematical programming tools to find the optimal EnM of the power plant in PPI mills, aiming to cost-effectively fulfil the total need of a plant for energy and steam. The study results showed that a detailed model of the power plant based on mass and energy balances, combined with the information from the electrical purchase contract, can be successfully used to enable optimal EnM.…”

Methodology Development for a Comprehensive and Cost-Effective Energy Management in Industrial Plants

“…Defining the equipments optimal set points Increasing the overall system efficiency (Sarimveis et al, 2003), (Arivalgan et al, 2000), (Von Spakovsky et al, 1995), (Frangopoulos et al, 1996), (Puttgen & MacGregor, 1996), (Tstsaronis & Winhold, 1985), (Temir & Bilge, 2004), (Tstsaronis & Pisa, 1994) Several studies on energy monitoring by using physical indicators to analyse energy efficiency developments in the manufacturing industry (especially the energy-intensive manufacturing industry) highlight the close relationship with the concept of specific energy consumption (energy use at the process level) and the international comparability of the resulting energy efficiency indicators as arguments advocating the use of physical indicators in the manufacturing industry (Farla & Blok, 2000), (Worrel at al., 1997). Moreover in (Kannan & Boie, 2003) the authors illustrate the methodology of energy management that was introduced in a German bakery with a clear and consistent path toward introducing energy management.…”

“…The methodology supports to identify maintenance condition through energy consumption characterization, predicting and control (Cesarotti et al, 2010). In (Sarimveis et al, 2003) an example of power systems management optimization through mathematical programming tools is presented. In other terms, the availability of optimization tools for the energy plant operation (i.e.…”

Iterative optimization of the economic efficiency of an industrial process within the validity area of the static plant model and its application to a Pulp Mill

“…According to Luyben (1989) it is usually much cheaper, safer and faster to conduct the optimization of plant operations on the basis of a mathematical model rather than experimentally. However, the significant number of studies is still concentrated on the optimization of single unit operations in Pulp Mills: Mcdonough, Uno, Rudie, and Courchene (2008) studied the optimization of the ClO2 requirements for the bleaching process; Tang, Wang, He, and Itoh (2007) optimized the Pulp Washing process; Sarimveis, Angelou, Retsina, Rutherford, and Bafas (2003) optimized the energy management in pulp and paper mills; Smith, Christlmeier, and Van Winkle (1986) studied the possibility of increasing of the recovery boiler throughput; Sidrak (1995) optimized the Kamyr Digester towards significant reduction in the amount of off-specification pulp. Klugman, Karlsson, and Moshfegh (2007) studied the energy consumption and production by the Pulp Mill; Savulescu and AlvaArgaez (2008) minimize the energy consumption through managing the direct heat transfer related to the water streams; Westerlund et al (1986) solved the equilibrium equations for the white liquor and optimized the lime feed rate; Santos and Dourado (1999) optimized energy consumption and the plant's production; Thibault et al (2003) concentrated their efforts on the multicriteria optimization of the plant.…”
