We supply the necessary technology for the implementation of a production of titanium dioxide

The production process of TiO2 pigment comprehends two steps.

The first step is the production of the base material. In the second step, the post treatment (see section Post Treatment (PT) ), the base material is coated to add additional properties like dispersibility or weatherability.

Two technologies are available for the production of the base material: The sulphate process (see section Sulphate Process (SP)) and the chloride process (see section Chloride Process (CP)).

In the sulphate process (SP) sulphuric acid is used. This process was developed in the 20’s of the last century.

In the chloride process (CP) chlorine is used. The process was developed in the 50’s of the last century.

Ti-Cons offers the technology for SP, CP and PT.

The following tables shows the advantages and the disadvantages of SP and CP:
Chloride Process (CP)Sulfate Process (SP)
Less flexible due to raw material quality
Wider range of raw material – especially Ilmenite – available
Better product quality regarding the optical and chemical properties
Product quality regarding the optical properties of Rutile base material is lower
Production of anatase pigment is not possible
Production of anatase pigment is possible
Smaller buildings
Larger buildings
Fewer vessels
More vessels
Less man power necessary
More man power necessary
Higher requirements to the qualification of the staff
Lower requirements to the qualification of the staff
Continuous Process
Mainly batch process
Less environmental impact due to less waste
More environmental impact due to more waste
Possibility to rework some of the waste to sellable co-products
Process needs co-product management and attractive markets for co-products
Requires stable production environment and infrastructure
Process is easier to handle because of batch process
Less amount of co-products
High amount of co-products
Because of the closed loop the process is more sensitive
Production does not stop totally if one step fails
Higher safety requirements due to the use of Cl2 and TiCl4
Lower safety requirements. In case of use of disulfuric acid, higher safety requirements are necessary
Higher degree of automation necessary
Lower degree to automation can be sufficient
Generally the production costs are lower
Generally the production costs are higher
