Question

Please explain how Coke is produced, including pollutants released and why the batteries must be continuously kept running?

Answer 1

Answer: Find the explanation below.

Explanation:

Coke is produced through a process known as destructive distillation. This involves heating coke at high temperatures (up to 1300°C) in an airtight environment (known as coke ovens). The result after the heating and distillation processes is metallurgical coke with no other constituents.

The coke battery is a combination of up to 100 coke ovens which are used at the same time. It is continuously kept running to allow the stable flow of gas. A typical coke oven consists of the coking, heating and regenerative chambers.

Pollutants released during the coking process include carbon monoxide, polycyclic aldehydes, ammonia, hydrogen sulfide, arsenic, lead, tar, carbon dioxide, amongst others.

Answer 2

Answer:

Coke is a fuel used in the steelmaking process that is created by heating coal in the absence of air.

Myth: The process of coke manufacturing is very complex and cannot be understood by anyone other than a scientist or engineer.

Reality: The manufacturing of coke involves a number of different processes. An understanding of these processes helps to understand the nature of the air pollution problem. These processes can be broken down and explained in simple terms.

The manufacturing of coke has many associated environmental and air pollution concerns. Coke manufacturing is present throughout the Allegheny County area and impacts communities throughout the county. However, it can be difficult to find specific information about how the coke process and its impacts works

Explanation:

Coke is produced by heating coal at high temperatures, for long periods of time. This heating is called “thermal distillation” or “pyrolysis.” In order to produce coke that will be used in blast furnaces, coal is usually thermally distilled for 15 to 18 hours, but the process can take up to 36 hours. The temperature of the ovens ranges between 900 and 1100 degrees Celsius (1,650 and 2,000 degrees Fahrenheit).

The first step in coke production is the delivery of coal to coke oven facilities, which is usually done by barge or railway. The second step in coke production is to process the raw material, coal, into a consistency appropriate for coke oven batteries.To achieve this consistency, coal is pulverized in a crusher and, if necessary, mixed with water and oil to control the density of the pulverized coal mixture.
