The cooling tower can transfer the processed waste heat to the atmosphere. They are an important part of any production system, and it is necessary to ensure proper function and structural stability. As a professional leader in concrete repair and maintenance, Sika can provide long-term production and innovative solutions to extend the service life of the cooling water tower and provide strategies to prevent many shutdowns.
CED accounts for the consumption of energy resources, namely the primary energy of renewable and non-renewable resources. The global warming potential measures the potential contribution to climate change, with a focus on the emission of greenhouse gases such as carbon dioxide (CO 2). POCP is a possible cause of summer smog and is related to ozone induced by sunlight on volatile organic compounds (VOC) and nitrous oxide (NOx).
An analysis of a construction project with a construction area of 20,000 square meters and a use period of 60 years, during which three innovative strategies were proposed: the traditional system (plan 1) and two Sika technical level systems (plans 2 and 3).
Save data, save time, and save the VOC content of all costs
1Traditional polymer and solvent-based products
2 times full innovation (4 times closed)
3Advanced polymer and solvent-based products
4 full innovations and 1 maintenance
5Advanced polymer and solvent-based products
6 Restructure and maintain the new structure, and perform 2 maintenance
In order to describe the environmental impact of these two plans, they were compared through a life cycle assessment (LCA). LCA is from the cradle to the grave, which means that it has to investigate the potential environmental impacts from the acquisition, production, application, disposal and final disposal of the original data.
In order to clarify the environmental impact of these two conditions, the cumulative energy demand (CED), global warming potential (GWP) and photochemical ozone generation potential (POCP) were determined.
1. Save more than 30% and 40% of data
Plan 1 uses lower-quality products, so it needs to repeat comprehensive innovation every 10 years (4 times in total). On the other hand, plans 2 and 3 use higher-quality products to reduce the frequency of innovation and data intensity, saving 60% and 80% of data respectively. Both are useful and time-saving solutions that prevent solvent-based traditional maintenance coatings.
As Plan 2 carried out a comprehensive innovation, the service life was further extended by 20 years. After that, only the innovative jacket is needed. In Plan 3, after the construction, the appearance was rebuilt and maintained directly after the construction, which further reduced the time for innovation. After that, only the coating was rewritten (2 times in total).
2. Higher resource efficiency
Plan 1 has higher data intensity than plans 2 and 3, and therefore has a much greater impact on the environment. These plans also replaced solvent-based housing coatings with water-based coatings and used solvent-based interior coatings with reduced volatile organic compound content.
3. More sustainable value
In order to show the overall environmental and economic performance of the most advanced system and the traditional system, the following is a relative comparison of the main sustainability drivers (data, time, cost, GWP, CED, POCP) in innovation. The systems of both technical levels have better overall performance, especially Plan 3.
