  PROJECT DESCRIPTION Our client has developed a production process of organic acids by fermentation. Organic acids need to be extracted and purify from the broth using a solvent extraction technology. TECHNICAL CHALLENGES In order to satisfy client requirements for its Project, Processium had to to identify a bio-based solvent for the extraction of acids and able to preserve microbes used for fermentation. OUR METHODOLOGY The methodology developed by Processium for the successful development of the Project had been developed as follow: screening of in - house database containing more than 1,000 industrial solvents data sets, identification of additional candidate determined thanks to a specific Computer Aided Molecular Design tool, modeling of solvent properties and prediction of missing data, identification of 5 solvents and measurement of distribution coefficients, performance evaluation of solvents…

Dynamic Lubricants ageing for a Rankine Cycle application

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…
