BAT examples from the Nordic iron and steel industry

image of BAT examples from the Nordic iron and steel industry

This report deals with "production of iron and steel" and "ferrous metals processing industry". The main purpose of the study is to support the coming updating work of the present BREF´s (BAT Reference Documents) in the corresponding areas, and also to promote the possibilities to include Nordic examples in these BREF-areas. The study made it very clear, that there are a lot of BAT-level processes, sub-processes, measuring technologies etc. in both areas. The study includes a total of 35 objects, which are rather well divided into the "steel production" and "ferrous metals processing" areas. In addition to the new descriptions of the Nordic BAT-level objects the both present BREF's are commented from today point of view. The project was carried out by MEFOS - Metallurgical Research Institute AB in Luleå, Sweden, and supervised by the Nordic BAT-group.

Comments on the present BREF's (2001)

In existing document, Table 9.1 on page 281, mercury emission levels between 6-4470 mg/ton liquid steel is presented. The average value for four German EAF plants reported to be 370 mg per ton of liquid steel. The extremely big variation in the emission level should be studied. The lowest value, 6 mg per ton liquid steel, is however wrong. The correct value should be 60 mg per ton of liquid steel. Ref. Jernkontoret, B. Lindblad.
