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