The chemical agents added to water that is used to process coal are largely undisclosed as manufacturers of these agents assert that the chemical composition is a "trade secret", thus keeping concerned citizens from knowing what chemicals are used in the process (Sludge Safety Project). When the slurry is dumped behind the dam, the larger ...
Process technology for making chemicals from coal. The MegaMethanol and MTP (methanol-to-propylene) concepts open new routes for coal monetization, and SNG (substitute natural gas) is a possible way to convert coal into a transportable fuel — methane. SNG can be used either for power generation or routed to pipelines as an admixture to ...

11.10 Coal Cleaning 11.10.1 Process Description1-2,9 Coal cleaning is a process by which impurities such as sulfur, ash, and rock are removed from coal to upgrade its value. Coal cleaning processes are categorized as either physical cleaning or chemical cleaning. Physical coal cleaning processes, the mechanical separation of coal from its
FIGURE 7-3. Variation of selected coal properties with coal rank. The chemical approach to characterizing coals is to determine the amounts of the principal chemical elements in them. In the jargon of the coal business, this procedure is called the ultimate analysis of coal. Carbon and hydrogen are the principal combustible elements in coal.
In chemical industry: Benzene …from the carbonization (heating) of coal, which produces coke, combustible gas, and a number of by-products, including benzene. Carbonization of coal to produce illuminating gas dates back in …
Eastman Chemical Company is an American company primarily involved in the chemical industry. Once a subsidiary of Kodak, today it is an independent global specialty materials company that produces a broad range of advanced materials, chemicals and fibers for everyday purposes. Founded in 1920 and based in Kingsport, Tennessee, the company now has more …
The commercial viability of the coal chemical leaching process depends on the efficient regeneration of spent reagents such as spent caustic and acid solutions, lowering energy consumption, and value-added products generation from solid wastes. Steel et al. (Steel and Patrick, 2004) successfully recovered spent HCl + HF by a sequence of ...
The U.S. coal industry serves a vital role in the nation's economy by producing fuel for more than half of its electricity. Despite the industry's importance, industry financial data for 2005—the strongest year for the coal industry in recent years—shows that it is a relatively small industry with revenues totaling $20 billion to $25 billion and net income between $1 billion and $2 ...

Coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), methane (CH 4), and water vapour (H 2 O)—from coal and water, air and/or oxygen.. Historically, coal was gasified to produce coal gas, also known as "town gas".Coal gas is combustible and was used for heating and municipal …
Coal chemical industry refers to the process of taking coal as raw material and converting coal into gas, liquid and solid fuels and chemicals through chemical processing. It mainly includes coal gasification, liquefaction, dry distillation, tar processing and calcium carbide acetylene chemical industry. Coal chemical processing process.
Coal Processing. The inputs in coal processing are high-value coking coal for pyrometallurgical industries and low-value thermal coal for power generation. ... The facility is currently being operated in a commercial mode by Eastman Chemical Company [45]. The process was developed to enhance IGCC power generation by producing a clean-burning ...

Coal chemicals Coal is used ia industry both as a fuel and ia much lower volume as a source of chemicals. In this respect it is like petroleum and natural gas whose consumption also is heavily dominated by fuel use. ... Frequendy, some or all of the chemical products of a coal conversion process are not isolated but used as process fuel.
The Bottom Line VS • ROI must be (MUCH?) higher for coal-based chemicals to induce large investments • Coal-based chemicals profitable when oil above $50/bbl • Coal-based chemicals lose money when oil below $35/bbl • Coal-based chemicals may be a viable option to monetize abundant, stranded, cheap coal reserves • Coal-to-chemicals tough … even for China … but …
Coal needs to be stored at various stages of the preparation process, and conveyed around the CPP facilities. Coal handling is part of the larger field of bulk material handling, and is a complex and vital part of the CPP.. Stockpiles provide surge capacity to various parts of the CPP.
