Atmospheric Pollution Control in Coke Ovens
Production of iron through BF route is still a dominant route and coke is a major raw material and energy source for the blast furnaces. The process of coal carbonization in slot ovens is one of the major sources of atmospheric pollution in an Integrated Steel Plant. Coke making process involves coal preparation, carbonization and coke handling operations. To meet the demand of Blast Furnaces o...
متن کاملHealth effects of banning beehive coke ovens and implementation of the ban in China
Environmental legislation and proper implementation are critical in environmental protection. In the past, beehive coke ovens (BCOs) were popular in China, resulting in enormous emissions of benzo[a]pyrene (BaP), a common indicator of carcinogenic polycyclic aromatic hydrocarbons. BCOs were banned by the Coal Law in 1996. Although BCO numbers have declined since the ban, they were not eliminate...
متن کاملOptical Microscopy and SEM Study of Pyrolytic Carbon Deposits from Coke Ovens
The presence of pyrolytic carbon deposits can cause a number of serious problems in the operation of a coke oven. They can inhibit the flow of gas out of the oven; their removal may cause damage to the refractories and the coke pusher equipment, in particular when the deposition is extensive, and can affect the sealing of the oven so leading to undesirable emissions. Some plants burn off the ca...
متن کاملRegeneration performance and carbon consumption of semi-coke and activated coke for SO₂ and NO removal.
To decrease the operating cost of flue gas purification technologies based on carbon-based materials, the adsorption and regeneration performance of low-price semi-coke and activated coke were compared for SO2 and NO removal in a simulated flue gas. The functional groups of the two adsorbents before and after regeneration were characterized by a Fourier transform infrared (FTIR) spectrometer, a...
