Understanding Sinter and Sinter Plant Operations. Sintering is a process of agglomeration of fine mineral particles into a porous and lumpy mass by incipient fusion caused by heat produced by combustion of solid fuel within the mass itself. The sintering process is a pretreatment step in the production of iron, where fine particles of iron ...

1. Introduction. The steel industry has negative implications in terms of pollutant emissions. The energy consumption of that industry is approximately 24 EJ/year, which represents 5% of the planet's primary energy consumption and corresponds to approximately 34% of global CO 2 emissions [1].This is an important reason to study the replacement of fossil fuels in that industry, and result in ...

Combustion technology in asphalt plants. During production, aggregates are dried and heated in a drum with a burner on the opposite side of the aggregates' inlet. The liquid fuel injected into the burner is atomised broken down into very small particles in order to increase the superficial surface area of the material and improve burning.

Coal is an essential primary energy source in modern industry. An important pathway of coal utilization is to gasify coal into syngas, which is then used for downstream production of numerous chemicals such as methanol and liquid fuels. Despite its wide applications, conventional coal gasification still faces challenges such as the use of a costly air separation unit and limited syngas H2/CO ...

In industrial chemistry, 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 ...

The main function of Coke Ovens is to convert coal into coke which is used as a fuel and reducing agent in the Blast Furnace. Its secondary function is to recover Volatile Matter and CO (Coke Oven) gas from coal and extract chemicals known as Coal Chemicals. CO gas produced is used for heating purposes in the plant. Heat from hot coke is

There are two basic methods for making liquid iron: (1) a coal based process consisting of coke ovens, a blast furnace, and a basic oxygen furnace, and (2) a process in which scrap steel and/ or DRI is melted by an electric current in an electric arc furnace (EAF). A plant using the electricity based process is called a minimill.

The absence of coke ovens and sinter plants in the FINEX process allow the capital investment of the FINEX to be reduced 20% compared to a conventional BF. Without cokemaking and sintering, the FINEX is more compact and takes less space. Continued cost advantages during operation can be realized as low cost and low quality raw materials (high alumina ore, high zinc ore, noncoking coals) use ...

The flow of coke oven gas is withdrawn from the battery by a centrifugal blower, the exhauster, and delivered through the gas vessels of the byproduct plant at a sufficient pressure for distribution as a fuel. Before passing to the exhauster, the gas is cooled in the primary gas coolers to around 25 deg C.

Any SO 2 present in the flue gas will be removed utilizing a chemical reaction with sodium carbonate (soda ash). The soda ash is automatically added to the scrubbing water through pH control. After cooling and scrubbing, the gas is led via an exhauster through an absorber, in which the gas flows countercurrent to the MEA solution flow.

How a Coke Plant Works. Coal is the main ingredient used to make coke. Iron is produced by inputting coal into a blast furnace. However, coal cannot be put directly into a blast furnace because of all the harmful byproducts that come from that. So, there is an intermediate process that occurs. Coal is converted into coke first.

The produced "syngas" consists mainly of carbon monoxide (CO), hydrogen (H 2 ), water vapor (H 2 O), and some other minor gases. These gases can then be separated through chemical processes and used as chemical feedstocks or products. Coal gasification can also be used to provide electricity in Integrated Gasification Combined Cycle (IGCC) plants.
