Metallurgical Processes Sulphuric Acid

Introduction. There are a variety of metallurgical process generating off-gases containing a variety of SO 2 concentrations and impurities. Each process is unique which dictates that the gas be treated in different ways in order to remove impurities and treat the SO 2 in the gas. The following table list the type of metallurgical operation and the type of hot gas cleaning employed prior to

Metallurgical Sulphuric Acid

The design and operation of a metallurgical sulphuric acid plant varies considerably because the nature of the gas that must be treated is different for each metallurgical operation. Sulphur dioxide concentrations can be as low as 1 to 2% in the case of a molybdenum roaster or over 50% in the gas of some flash smelting process with oxygen enrichment.

Wet sulfuric acid process Wikipedia

The wet sulfuric acid process (WSA process) is one of the key gas desulfurization processes on the market today. Since the Danish catalyst company Haldor Topsoe introduced and patented this technology in the late 1980s, it has been recognised as an efficient process for recovering sulfur from various process gases in the form of commercial quality sulfuric acid (H 2 SO 4), with simultaneous

Roasting (metallurgy) Wikipedia

Roasting is a process of heating of sulphide ore to a high temperature in presence of air. It is a step of the processing of certain ores.More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation.

Sulfuric acid Manufacturing process of Sulfuric acid

Concentrated sulfuric acid (93-98 %) is used in the manufacture of fertilizers, explosives, dyes, and petroleum products. The starting material for sulfuric acid manufacture is clean, dry sulfur dioxide (SO2) gas. This can be obtained by burning molten sulfur, from metallurgical off-gases or by decomposing spent sulfuric acid.

Sulfuric Acid Wet gas Sulfuric Acid (WSA) H2SO4

The WSA process is a wet gas catalytic process. The concentrated sulfuric acid is produced by condensation from a wet process gas. Drying of the process gas prior to treatment in a WSA plant therefore becomes superfluous, hence generation of waste water and loss of sulfur are avoided.

Sulfuric acid Sulfur dioxide oxidation H2SO4 SO2
