Cement Industry In China
China is the largest cement producer in the world. As of 2004, it was responsible for 60% of cement global production. In 2017, China produced 2,400,000 metric tons of cement, whereas other countries produced about 1,728,300 metric tons. Cement production adds one ton of carbon dioxide (CO2) per ton of cement. According to engineering company FLSmidth, in order to heat a cement kiln with waste, about three times more waste is needed than the amount of coal used, reducing emissions by only about 10%. However, the Chinese cement industry has improved energy efficiency. In 2017, it accounted for 57% of the global industry's output, but only 52% of its emissions. However, the emission reductions from energy efficiency measures are vague compared to those that could be achieved with innovative technologies such as carbon capture and storage (CCS), which sequesters emissions.

Cement
A cement is a binder, a chemical substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel ( aggregate) together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is behind only water as the planet's most-consumed resource. Cements used in construction are usually inorganic, often lime- or calcium silicate-based, and are either hydraulic or less commonly non-hydraulic, depending on the ability of the cement to set in the presence of water (see hydraulic and non-hydraulic lime plaster). Hydraulic cements (e.g., Portland cement) set and become adhesive through a chemical reaction between the dry ingredients and water. The chemical reaction results in mineral hydrates that are not very water-soluble. This allows setting in wet conditions or u ...

Carbon Dioxide
Carbon dioxide is a chemical compound with the chemical formula . It is made up of molecules that each have one carbon atom covalent bond, covalently double bonded to two oxygen atoms. It is found in a gas state at room temperature and at normally-encountered concentrations it is odorless. As the source of carbon in the carbon cycle, atmospheric is the primary carbon source for life on Earth. In the air, carbon dioxide is transparent to visible light but absorbs infrared, infrared radiation, acting as a greenhouse gas. Carbon dioxide is soluble in water and is found in groundwater, lakes, ice caps, and seawater. It is a trace gas Carbon dioxide in Earth's atmosphere, in Earth's atmosphere at 421 parts per million (ppm), or about 0.042% (as of May 2022) having risen from pre-industrial levels of 280 ppm or about 0.028%. Burning fossil fuels is the main cause of these increased concentrations, which are the primary cause of climate change.IPCC (2022Summary for pol ...

FLSmidth
FLSmidth & Co. A/S is a Danish multinational technology company based in Copenhagen, Denmark. With almost 11,000 employees worldwide, it provides the global mining and cement industries with equipment and services. For the mining industry, the company provides technology for copper, gold, nickel, zinc and lithium mining, and for the cement industry, it provides technology for cement production.

A/S was founded in Copenhagen on 2 January 1882 by Frederik Læssøe Smidth ( da). It was initially a consultancy business whose main focus was to purchase machinery and build small machines for local craftsmen. Within a few years the firm, called “Technical Bureau” at the time, specialised in machinery for the brick and tile industry. In 1887 two engineers, Poul Larsen and Alexander Foss, were made ...

Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other Chemical element, elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat which is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous (Pennsylvanian (geology), Pennsylvanian) and Permian times. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its Electricity generation, electricity. Some iron and steel-maki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Efficient Energy Use
Efficient energy use, or energy efficiency, is the process of reducing the amount of energy required to provide products and services. There are many technologies and methods available that are more energy efficient than conventional systems. For example, building insulation, insulating a building allows it to use less heating and cooling energy while still maintaining a Thermal comfort, comfortable temperature. Another method made by Lev Levich is to remove energy subsidies that promote high energy consumption and inefficient energy use. Improved energy efficiency in Green building, buildings, industrial processes and Energy efficiency in transport, transportation could reduce the world's energy needs in 2050 by one third. There are two main motivations to improve energy efficiency. Firstly, one motivation is to achieve Operating cost, cost savings during the operation of the appliance or process. However, installing an energy-efficient technology comes with an upfront cost, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Capture And Storage
Carbon capture and storage (CCS) is a process by which carbon dioxide (CO2) from industrial installations is separated before it is released into the atmosphere, then transported to a long-term storage location.IPCC, 2021Annex VII: Glossary atthews, J.B.R., V.

Industry In China
The industrial sector comprised 36.5% of the gross domestic product (GDP) of the People's Republic of China in 2024. China is the world's leading manufacturer of chemical fertilizers, cement and steel. Prior to 1978, most output was produced by state-owned enterprises. As a result of the economic reforms that followed, there was a significant increase in production by enterprises sponsored by local governments, especially townships and villages, and, increasingly, by private entrepreneurs and foreign investors, but by 1990 the state sector accounted for about 70 percent of output. By 2002 the share in gross industrial output by state-owned and state-holding industries had decreased with the state-run enterprises themselves accounting for 46 percent of China's industrial output. In November, 2012 the State Council mandated a " social risk assessment" for all major industrial projects. This requirement followed mass public protests in some locations for planned projects or expan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
