SJSC "TITAN" INTRODUCES PRODUCT QUALITY IMPROVEMENT MEASURES.

According to SJSC "Titan" press-cutting service, during 2001 - 2003 the company introduced a number of arrangements aimed for pigment titanium dioxide quality indicators stabilization and improvement.

There have been performed reconstruction of "white" filtration equipment with drum vacuum-filters replacement by leaf ones (Moore filters) and hydrolysis process automation. Besides that, there have been purchased and installed "black" filtration press-filters (prehydrolysis solutions filtration). The process of hydrolytic acid extraction has been automated in ammophos workshop.

Taking into account both implemented and planned automation of all the production processes, the central control room of the company has also been completely re-equipped.

Mr. Eduard Kurmachov, Vice Technical Director, informs: "The main priorities of the company technical policy are production process technical re-equipment and continuous research aimed for finished product quality improvement".

In 2004-2006 SJSC "Titan" plans to introduce a number of technical measures:

• Second stage of "white" filtration equipment reconstruction with full process transition to leaf vacuum-filters (Moore filters) in order to improve whiteness and yellowness indicators and also to increase product output.
  
• Usage of sheet metal scraps instead of cast-iron scraps for reduction of titanium sulphate solutions in order to stabilize titanium dioxide qualitative characteristics;
  
• Replacement of wet grinding ball mills by bead mills in order to improve pigment dispersibility characteristics;
  
• Replacement of final drying stage continuous-belt drier by modern boiling-bed or spray-type driers in order to broaden produced titanium dioxide marks assortment;
  
• Full automation of pigment titanium dioxide manufacturing process;
  
• Reconstruction of decomposition reactors gas-cleaning units and calcination klins with the aim of emissions level decrease in order to meet requirements of European norms and regulations on emissions.
