“…The costs of the proposed heat exchanger network retrofits were calculated based on area requirements, with surface area costs taken from recent pinch studies of similar mills [6]. The cost of piping was estimated at 50% of the installed heat exchanger cost based on typical cost estimation factors presented in [4], since the distances between streams were not investigated.…”

“…To analyze these options, more information regarding yearly variations in bark boiler firing, steam system and demand of heating and cooling in general are required. The effect of these seasonal variations on the steam-saving potential could, however, be estimated using the results of previous studies [6]. The effect on the overall energy balance of the mill could, for example, be studied using the reMIND tool, thereby connecting the results from this pinch analysis to other studies within the Billerud project.…”

Abstract:The pulp and paper industry, with its wood biomass feedstock, has promising opportunities to become a key player in the biorefinery arena. A successful implementation of biorefinery pathways requires optimization of the energy system through process integration, and can lead to both increased and diversified revenues as well as a r eduction of global CO 2 emissions. This paper presents the results from a pinch analysis of a partly integrated Kraft pulp and paper mill. The objective was to identify the potential for energy efficiency improvements, focusing on possibilities to save steam. Another objective was to identify practical retrofit solutions for the mill heat exchanger network and to estimate the costs for the required investments. The potential for energy savings at the mill is estimated at 18.5 MW, i.e. 12% of the current steam demand. Two alternative retrofit options are presented in the paper. A straightforward retrofit that is easy to implement enables 5.8 MW of steam to be saved at a cost of €0.13 million per MW of saved steam. A second more extensive retrofit option is also presented which could achieve steam savings of 11 MW at a cost of €0.14 million per MW of saved steam. Assuming that the steam savings lead to a reduced use of bark fuel in the power boiler, the payback period of both energy saving retrofit investments is estimated to be less than about 16 months.

“…The existing research into irrigation energy consumption is mainly about implementation effect of water-saving irrigation rather than GHG emissions (Li et al 2007;Wang 2006;Liu 2001). On the other side, the research on energy-saving and emission reduction is mostly concentrated on such fields as industry, transport, and building (Wilde and Voorde 2004;Ouyang et al 2009;Kwak et al 2010;Persson and Berntsson 2009;Zhang and Wang 2008;Yan and Crookes 2009) but not on irrigation. This paper is the first attempt to study the WSI in relation to climate change.…”

A warming climate system is now an indisputable fact. An effective response to climate change should include both mitigation and adaptation. Water is essential to human survival and social development. But the shortage of water resources is a worldwide problem, which in China has been exacerbated by climate change. In order to find out how to cope with climate change successfully, this study, on the basis of China statistical data 2007-2009, quantitatively analyzes the role of water saving irrigation (WSI) in addressing climate change. The study shows that water saving irrigation (WSI) can serve as a useful enabler in dealing with climate change. From the perspective of mitigation, the 3-year total CO 2 emission reduction stands at 34.
