Identification of the pollution source in steel plant

Abstract

Kimitsu Works is among the biggest steel mills in the world with several big blast furnaces and other steelmaking equipments which is located near the sea. There are three high chimneys in the mill which produce plume pollution and there are a big coal yard and many dusty roofs which produce dust pollution when the sea wind brings the dust up. Unfortunately, the downtown is just located at the downwind direction about 4km away. To reduce the pollution to the downtown, the administrator of Kimitsu works wants to identify the main sources of the pollution then to adopt some methods such as fixing new dust filter on the top of the chimneys or spraying water to the locations where main dust pollution are produced. Some monitoring instruments which are placed somewhere not far from the pollution sources in the downwind direction is used to measure the concentrate of the plume and dust. During three very busy days, we set up some mathematical models for this problem, obtained some initial results and made clear what future work should be done.
