  PROJECT DESCRIPTION Our customer wishes to know the solubility of a solid inorganic salt in an aqueous solution at 80 °C. The influence of pH of this solution on the solubility of the salt must be estimated. Measures are led at 3 different hydrogen potential by going from pH 4 (acidic), pH 7 (neutral) and to pH 9 (basic). TECHNICAL CHALLENGES Why do we speak about challenges? For two main reasons:The solubility of the salt in the liquid is very high. The first difficulty is to identify an analytical methodology adapted to the inorganic solid. ICP-AES had been selected as the most accurate technique for the analysis of this molecule and was successfully used. Thermogravimetry study was coupled with a specific chemical analysis to insure reliability of the supplied results because of…

Case study: Dynamic Lubricants ageing for a Rankine Cycle application

Case study: Dynamic Lubricants ageing for a Rankine Cycle application

Specialty Chemicals, Oil and Gas
  PROJECT DESCRIPTION For companies in the transport sector, reducing vehicle fuel consumption and CO2 emissions is a major challenge. Our client for this project wanted to implement a Rankine cycle to recover thermal energy produced by a vehicle. The energy recovery concept was to exploit the thermal expansion of a heat transfer fluid to drive a turbine or piston. TECHNICAL CHALLENGES Tests should be performed continuously over hundreds of hours on a mixture of lubricants and coolants under conditions which precisely represent the operating conditions of the thermal cycle (temperatures over 250°C and pressures of 30 bar). OUR METHODOLOGY Our teams of experts conducted tests on the mixture in order to: Select a suitable oil which maintains steady operating conditions over time Simulate the product behaviour over many hundreds of…
