The gas generated from coal contains hydrogen (H 2), but since FT-IR is insensitive to H 2, a high-sensitivity hydrogen gas sensor using a semi-conductor (SnO 2) is provided downstream of the FT-IR. The details of the monitoring system and the investigation re-sults of the gas generation during coking obtained with the system are presented below. The use of coke ovens produces metallurgical coke and coke oven gas. The coke is used in the blast furnace process, and the coke oven gas is used as the major fuel in the whole steel mill. Iron ore in the form of fines is normally processed in sintering plants into sinter, and in some cases in pelletizing plants to iron ore pellets.
The first plant for dry coke quenching was created in 1937 in the USSR. Then design of the plant has been improved. ... Coke oven gas is deeply cleaned from hydrogen sulfide and hydrogen cyanide ... The off gases liberated in the high-temperature carbonization of coal in coke ovens were collected, scrubbed and used as fuel. Depending on the goal of the plant, the desired product was either a high quality coke for metallurgical use, with the gas being a side product, or the production of a high quality gas, with coke being the side product.
The gas has a heating value of about 20,000 kJ/m 3. Typically, coke-oven gas is obtained from a battery comprising a number of narrow, vertical chambers, or ovens (0.5m wide, 5m high and 12m long) built of silica brick that are separated by heating ducts, such that heat is transmitted to the coal through both sides of the chamber walls. of ethanolamine (Girbotol), although several other methods have been used in the past. The clean coke oven coal gas is used as fuel for the coke ovens, other plant combustion processes, or sold. 12.2.3 Emissions And Controls Particulate, VOCs, carbon monoxide and other emissions originate from several byproduct coking
