ABSTRACT:
A good understanding and prediction of the phase equilibrium of the fatty acid methyl ester (FAME) + glycerol + methanol ternary system is needed to design and optimize the separation unit of the biodiesel production process. In this work, new experimental vapor−liquid−liquid data on the ternary system have been measured at temperatures between 333.15 and 473.15 K. In addition, new data have been gathered on the methanol + glycerol [vapor−liquid equilibrium (VLE)] and methanol + methyl oleate (VLE and liquid−liquid equilibrium) binary systems. A group contribution method combined with a statistical associating fluid theory equation of state (GC-PPC-SAFT) proposed earlier by our group (Tamouza, S., Passarello, J.-P., Tobaly, P., and de Hemptinne, J.-C.Group contribution method with SAFT EOS applied to vapor liquid equilibria of various hydrocarbons series. Fluid Phase Equilib. 2004, 222−223, 67−76) and recently extended to predict VLE of heavy esters and their mixtures (Nguyen Huynh, D., Falaix, A., Passarello, J.-P., Tobaly, P., and de Hemptinne, J.-C.Predicting VLE of heavy esters and their mixtures using GC-SAFT. Fluid Phase Equilib. 2008, 264, 184−200) is here applied to model vapor liquid−liquid equilibria of methanol + glycerol + methyl oleate. The SAFT parameters for the glycerol pure component have been regressed using two association schemes (4C and 3X2B). The dispersive binary interaction parameters kij have been regressed on the binary systems. The group contribution scheme was used for predicting the ester properties.

PROCESSIUM thanked all participants of the symposium "Thermo-physicals data: acquisitions, processing and use of banks”, June 18th, 2010.
This day was organized in partnership with the Thermodynamics workgroup of the French Company of Engineering Processes (SFGP) on the site of PROCESSIUM, La Doua, Lyon.
Theme: Thermo-physicals data: acquisitions, processing and use of banks.

Development of processes, or the search for substitutes requires many thermophysical experimental data manipulation. If a large number of databases exist, accessible data are often of very varying qualities, either unavailable or even non-existent in the area of pressure-temperature-composition for existing applications.
Through this day, we propose a thought on the current data availability, their validation and how they are used. Examples of applications are mentioned, or the development of models (regressions or validations), either for establishing reverse tools (QSAR - QSPR) to identify products meeting the most searched properties criteria.

PROCESSIUM has been selected by OSEO to be member of OSEO EXCELLENCE 2010, network of 2 000 outstanding contractors selected to represent growth companies.
OSEO mission is to promote innovation and business growth to restore the French competitiveness and the emergence in France of a greater number of mid-cap companies. This is the meaning of his daily activities through its three businesses: innovation, financing and warranty.
To give more meaning and encourage more growth companies, OSEO has decided to complement its plan by creating a digital network consisting of 2 000 customers among contractors whose growing prospects appeared to be the most promising.
This selection has been made by OSEO business experts, leaders who know their customers, their projects, their ability to grow and become tomorrow's leaders.
Through this network, OSEO allows these members to benefit from a strong resonance: to be seen and heard by medias and government that benefit a direct connection with a population that is essential to the vitality of our economy.
OSEO excellence is also a place of exchanges, sharing of common problems and solutions, leads, contacts... Because of its significant number, 2 000, and its proper distribution throughout the metropolitan area, this community is an ambassador for all business growth.
Each month, through a mini-survey, a question inside actuality, the members will be interviewed and the results will be published to make known their views and expectations.

Pascal ROUSSEAUX, President and founder of Processium, member of the Cluster Axelera, participates in the steering committee "Ecosystem - Eco-designed processes" and in the strategic axis "Plant of the future" - January 27, 2010.
The cluster's ambition is to build a chemistry-environment sector in Rhône-Alpes with an international visibility.
This ambition is available in 4 major strategic objectives:
1. Leading the construction of a scientific and economic attractive sector combining chemistry and environment
2. Enabling technological breakthrough on thematic fields related to the market needs
3. Becoming an international showcase of innovation in the field of chemistry environment
4. Federate the construction of a French Ecotechnologies network
Based on a global market survey conducted by Axelera, late 2008 early 2009, 8 target areas were identified for the cluster. In order to develop innovation projects declined around these 8 market segments targets, 5 strategic themes have been selected, including the "Factory of the Future - Clean Processes."

In order to improve the quality of our services, our laboratory of measurements and tests is investing in new advanced analytical equipment to complement the existing analytical fleet:
- a new 7890A GC chromatograph (Agilent Technologies) equipped with an automatic sampler of 150-vials capacity to ensure the accuracy and precision of results. This device has a resolution that allows search for compounds to traces and offers greater reliability of results.
- a coulometric Karl Fisher apparatus (Metrohm) to quantify the amount of water in a solid or a liquid, in domains of concentrations below those used for volumetric device. The measurements carried out are more accurate (down to tens of ppm) and in a wider range.
