We analyzed 23 energy efficiency technologies and measures applicable to the processes in the cement industry. Using a bottom-up electricity conservation supply curve model, the cumulative cost
China Energy Group, Energy Analysis and Environmental Impacts Division Lawrence Berkeley National Laboratory 1. Introduction China’s cement industry produced 2,360 million metric tons (MMt) of cement in 2015, accounting for 57 percent of the world’s totalF cement production (NBS 2015a; USGS 2016). Consistent with the Chinese cement industry
24/01/2008· cement, energy efficiency: Abstract: This report provides information on the energy savings, costs, and carbon dioxide emissions reductions associated with implementation of a number of technologies and measures applicable to the cement industry. The technologies and measures include both state-of-the-art measures that are currently in use in
cement industry, energy efficiency, shandong, supply curve: Abstract: China's cement industry, which produced 1,388 million metric tons (Mt) of cement in 2008, accounts for almost half of the world's total cement production. Nearly 40% of China's cement production is from relatively obsolete vertical shaft kiln (VSK) cement plants, with the
Downloadable (with restrictions)! We have studied the cement industry in China to determine the prospects for renovation and for building new facilities during the 1990s, and, in particular, the prospects for improved energy efficiency. The potential is good for renovating most vertical-kiln plants to improve their energy intensity 10–30% while substantially increasing their capacity and
More efforts needed. From 2014 to 2016, the direct CO 2 intensity of cement showed little change, as thermal energy efficiency improvements were offset by a slight increase in the global clinker-to-cement ratio. To meet the IEA SDS objectives, the direct CO 2 intensity of cement needs to decline by 0.3% annually through to 2030, even as cement production is expected to grow.

Energy Efficiency and CO2 Emissions from the Global Cement Industry Michael Taylor, Cecilia Tam and Dolf Gielen Energy Technology Policy Division International Energy Agency
Highlights We analyze the energy consumption and CO 2 emissions in China's cement industry. The growth of cement output is the most important driving factor. The efficiency policies and industrial standards significantly narrowed the gap. Efficiency gains cannot compensate for the huge increase in cement production. The potentials of energy-saving of 26% and CO 2 mitigation of 33% exist based
China's annual cement production (i.e., 1868 Mt) in 2010 accounted for nearly half of the world's annual cement production in the same year. We identified and analyzed 23 energy efficiency technologies and measures applicable to the processes in China's cement industry.
Therefore, implementation of energy efficiency measures is more cost-effective than a solely end-of-pipe based policy in China's cement industry. The plant managers and end users can consider using energy efficiency measures to reach new air pollutants emission standards in China's cement industry.
Taking China’s cement industry as the main focus, this paper carries out quantitative analysis of the relationship between energy consumption in the cement industry and a number of variables: energy structure, energy prices, energy efficiency and total output value of the cement industry based on a cointegration model. The study further
12/06/2017· The inforgraphic below is prepared by Global Efficiency Intelligence, LLC to summarize some key information on energy use and emissions in the cement industry. Global Efficiency Intelligence, LLC has experience conducting various projects and studies on energy efficiency, GHG and other emissions reduction, energy benchmarking, and alternative
This study analyzes current energy and carbon dioxide (CO 2) emission trends in China's cement industry as the basis for modeling different levels of cement production and rates of efficiency improvement and carbon reduction in 2011-2030. Three cement output projections are developed based on analyses of historical production and physical and
13/09/2018· China’s leadership has implemented harsh measures to mitigate environmental degradation caused by the cement and other energy-intensive industries. The 11 th Five-Year Plan mandated aggressive energy-efficiency goals for the country’s top 1,000 most energy-intensive industries. China’s cement industry was previously dominated by polluting
13/07/2015· China's cement industry has entered a 'new normal,' according to the country's larger producers. In its 2014 annual report, CNBM reported a 19.4% fall in cement industry investments. During the year, 81Mt/yr of cement capacity was removed and 70.3Mt/yr was added, while China's top 10 cement producers increased their market share to 52%.
Downloadable (with restrictions)! In this study, 16 cement plants with New Suspension Preheater and pre-calciner (NSP) kiln were surveyed. Plant energy use was compared to both domestic (Chinese) and international best practice using the Benchmarking and Energy Saving Tool for Cement (BEST-Cement). This benchmarking exercise indicated an average technical potential primary energy
China produces the majority of the world’s cement, a powdery substance that is mixed with sand, gravel and water to make concrete. In the period 2011-2013, China produced more cement than the US in the entire 20 th century. The Chinese cement industry has already made improvements in energy efficiency.

Efficiency Gains . According to PCA’s Labor-Energy Input study, labor efficiency, measured in cement tons per employee hour, has more than doubled in the past 30 years. This spike in labor efficiency is the result of industry efforts to increase efficiency by automating production and closing small kilns. The average kiln in use today is
Deployment of best available technologies will be important to raise industry energy efficiency. Adoption of waste heat/gas recovery and cogeneration could be expanded in sub-sectors such as iron and steel and pulp and paper. Developing plant-level action plans and sharing of best practices may improve uptake of best available technologies.
