Flow Measurement of Sulphuric Acid in Titaniumdioxide Production. Titanium dioxide, a widely used basic chemical for paints, cosmetics, plastics and much more, can be processed either by the chlorine or the sulphate process. By applying the sulphate process, an approx. 24% concentrated sulphuric acid is formed during the production process. In many cases, the diluted acid is completely ...
In order to concentrate the diluted sulfuric acid from the titanium dioxide (TiO 2) production of sulphate process, a new concentration process was proposed by coupling chemical dehydration and multi-effect evaporation.The ferrous sulfate monohydrate (FeSO 4 ·H 2 O), as the dehydrant, was added to the diluted sulfuric acid to form ferrous sulfate heptahydrate (FeSO 4 ·7H 2 O) according to ...
There are two processes used to leach titanium from ore: the chloride process and the sulfate process. The chloride process uses chlorine gas (Cl 2) and coke (C+) at elevated temperature to create titanium tetrachloride (TiCl
raw material for the production of titanium dioxide by both the chloride [2–4] and sulfate methods. Sulfuric acid leaching of mineral rocks and concentrates containing titanium is a common method for the production of a pigment titanium dioxide. Presently, ways to intensify this leaching method

High-grade titanium dioxide is produced by (a) reacting ilmenite or titanium-containing slag with sulfuric acid, (b) dissolving the material from (a) with water or dilute sulfuric acid, (c) separating insolubles from (b) to obtain a black solution containing titanyl sulfate and foreign metal salts, extracting titanyl sulfate from the black liquor with sulfuric acid and an organic medium ...
Sulfuric acid manufacturing processes use different types of reactors. Perhaps the most common type has the reactor divided into adiabatic sections with cooling between the sections (recall Figure 8-8). One such layout is shown in Figure R8.4-2. In the process in Figure R8.4-2, gas is brought out of the converter to cool it between stages, using the hot converter reaction mix-ture to preheat ...

In any case, today we will be looking at the contact process in detail. Contact process for manufacturing of sulphuric acid: Steps involved in the manufacturing of sulphuric acid are as stated below: Preparation of sulphur dioxide. Conversion of sulphur dioxide into sulphur trioxide. Conversion of sulphur trioxide formed into concentrated H 2 SO 4.

15.03.2010· Titanium Dioxide (TiO2) Production and Manufacturing Process TiO2 is produced from either ilmenite, rutile or titanium slag. Titanium pigment is extracted by using either sulphuric acid (sulphate process) or chlorine (chloride route). The sulphate process employs simpler technology than the chloride route and can use lower grade, cheaper ores.

In addition, manufacturers of sulfate process titanium dioxide usually have sulfate acid production devices due to the need of a large amount sulfate acid. The invention relates to a method and a device for producing concentrated sulfuric acid by recycling waste acid from sulfate process titanium dioxide production. The method comprises the ...

The Sulfacid ® process has been especially developed to meet the dual objectives of SO 2 removal from waste gases generated by chemical and metallurgical processes and transformation into industrial grade sulfuric acid. It lends itself particularly well to applications where sulfuric acid can be directly used, for example copper or fertilizer industry, titanium dioxide production or similar ...
Sulfuric acid is used in the manufacture of paints, detergents and fertilisers. The contact process demonstrates a reversible reaction used in the production of sulfuric acid.
