  PROJECT DESCRIPTION Our customer wishes to know the kinetic of deactivation of its catalyst under industrial conditions in order to adapt the sizing of corresponding process accordingly. In addition to this, the definition of the frequency of replacement of the catalyst was also an issue to secure productivity. TECHNICAL CHALLENGES Test should be performed continuously over hundreds of hours on a reactive mixture under conditions which precisely represent the operating conditions (temperatures over 250°C and pressures of 6 bar). The test needed to implement a dedicated bench to test the catalyst in continuous mode. OUR METHODOLOGY Design and development of a continuous reaction bench equipped with a tubular reactor working in conditions close to those of the process (6 bar and 250°C). Regular sampling from the reactor for 30 days.…

  PROJECT DESCRIPTION The objective of this study is to acquire data to design an extractive distillation process for separating light hydrocarbons. TECHNICAL CHALLENGES A key element of success in the study is the measurement of vapor-liquid equilibria at pressures of 2 to 5 bar, to determine the liquid and vapor compositions in a mixture of heavy and light components (boiling point difference > 230°C). OUR METHODOLOGY We undertook this study by: Developing efficient analytic methods, Developing a suitable experimental strategy to acquire measurements in line with customer’s project and time constraints. RESULTS The measurements were carried out successfully in our labs, and Processium was able to provide: A feedback on notable issues encountered, particularly degeneration of seals or corrosion problems Data values which allowed our customers to better understand their…

  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…

  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…

  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).
