Avoid Sulfuric Acid Corrosion In Metallic Stacks, João F. Gomes
Avoid Sulfuric Acid Corrosion In Metallic Stacks, João F. Gomes
João F Gomes
Acidic gaseous effluents frequently cause corrosion on metallic stacks. This paper presents a method for prevision of probability of corrosion occurrence caused by gaseous effluents containing sulphur oxides which is based on the sulphur trioxide and moisture content measured in stack

Emissions Of Dioxin And Dibenzofuran From Electric Arc Furnaces, João F. Gomes

This paper describes work done in order to clarify the formation mechanism of highly toxic micropollutants, such as dioxins and dibenzofurans, from electric arc furnaces used in the production of carbon steel from scrap. The study is allowing to derive relationships between the levels of airborne micropollutants and the operational parameters of the production process so that an abatement of pollution could be achieved. By using the European standard method CEN 1948 for dioxin like compounds sampling and measurement, it was possible to determine the characteristic fingerprint of micropollutants emitted by this particular stationary source.
