Elkem Silicones Victor

Creation of a manufacturing unit for chemical intermediates

Elkem is one of the world’s leading suppliers of advanced silicone-based materials, that are shaping a more sustainable future through the use of natural raw materials, renewable energy and human ingenuity.


This project is part of an approach aimed at ensuring the long-term viability of Elkem’s production activities in France in line with regulatory and environmental requirements, with the main catalyst being the technological risk prevention plan for its various sites in Auvergne-Rhône-Alpes. A production activity at Elkem Silicones’ Saint-Fons site has been transferred to the Roussillon site, leading to the construction of a multi-purpose hydrolysis unit using the best available techniques to reduce industrial risk and environmental impact. From design to operation, the project has incorporated all 4.0 technologies, including process simulations, collaborative 3D dimensional design, remote construction monitoring, remote start-up assistance and full digitisation of technical documentation.

Artelia managed all phases of the project, from preliminary design studies through to acceptance of the installations, covering all trades (civil engineering, structure, boiler making, equipment, piping, electricity, instrumentation, etc.). One of the key elements in the manufacture of this type of product is to limit clogging and fouling, by reducing the number of cleaning or inter-campaign phases. To achieve this, our teams have paid particular attention to the design of the piping network. They achieved highly satisfactory results, resulting in an increase in production that exceeded the target initially set. They also effectively managed the rationalization of space, as the new manufacturing structure and associated packaging area had to be inserted into the heart of the existing facilities, within a constrained space.
