2 2 RM/SPE/LUB/FOR/LTT2 – Pierre BELOT & Bertrand DESEUMAUX– 04A11a Ceran (September 2004) Requirements of the European market concerning the main types of lubricants Resistance to high temperatures Super high pressure Corrosion protection Water resistance Self-recovery Mechanical stability and resistance to shift Good pumpability (providing the pressure in the centralised lubricant feed system is no lower than 60 bar) Cost requirements: the average cost of lubricant with a Ca thickener does not exceed 10% - 25% of that of the most widespread Li thickener, even though it has higher operating attributes

3 3 RM/SPE/LUB/FOR/LTT2 – Pierre BELOT & Bertrand DESEUMAUX– 04A11a Ceran (September 2004) (R - SO3)2Ca + CaCO3 (amorphous phase) + promoting agent + polar solvent (R -SO3)2Ca + CaCO3 The process of slow homogenisation is very important for the future stable operation of the lubricant (TOTAL Ceran) Thickener: basis of the technology

4 4 RM/SPE/LUB/FOR/LTT2 – Pierre BELOT & Bertrand DESEUMAUX– 04A11a Ceran (September 2004) Thickener – base (standard) Calcium sulphonate (composite)

5 5 RM/SPE/LUB/FOR/LTT2 – Pierre BELOT & Bertrand DESEUMAUX– 04A11a Ceran (September 2004) Vaterite Calcite A poor barrier for water A good barrier for water Possible forms of CaCO 3 Stable system Unstable system The secret of the thickener – stable conditions of homogenisation, observance of the technology

6 6 RM/SPE/LUB/FOR/LTT2 – Pierre BELOT & Bertrand DESEUMAUX– 04A11a Ceran (September 2004) New technologies: the additive is a part of the thickener Ca Carbonate Organic chains Size: нм Additives and admixtures

7 7 RM/SPE/LUB/FOR/LTT2 – Pierre BELOT & Bertrand DESEUMAUX– 04A11a Ceran (September 2004) Advantages of the composite thickener technology

8 8 RM/SPE/LUB/FOR/LTT2 – Pierre BELOT & Bertrand DESEUMAUX– 04A11a Ceran (September 2004) Qualitative improvement of indications

9 9 RM/SPE/LUB/FOR/LTT2 – Pierre BELOT & Bertrand DESEUMAUX– 04A11a Ceran (September 2004) TOTAL CERAN : Properties Advantages of the composite calcium thickener with modified additives. Anti-wear properties Anticorrosion properties Thermal stability Protective properties Extreme pressure Mechanical stability Service and storage life

10 10 RM/SPE/LUB/FOR/LTT2 – Pierre BELOT & Bertrand DESEUMAUX– 04A11a Ceran (September 2004) High-temperature attributes Dropping point CERAN – Wide temperature range of application

11 11 RM/SPE/LUB/FOR/LTT2 – Pierre BELOT & Bertrand DESEUMAUX– 04A11a Ceran (September 2004) High operational attributes – broad capabilities for use Ferrous and non-ferrous metallurgy Woodworking and paper production Application in marine units and mechanisms Heavy-duty bearings
