Description

The pilot units of Vinci Technologies dedicated to polymerization do not, by themselves, address the full scope of the industrial challenge. Upstream of polymerization, the synthesis of monomers must be considered, as it represents a major strategic lever within the polymer materials value chain. The overall performance of a polymer depends as much on the quality and cost of the monomer as on the polymerization process itself.

New monomer synthesis processes are regularly developed to reduce production costs, improve reaction selectivity, or increase yields. For example, ethylene produced by the oxidative dehydrogenation of ethane or the use of bio-based feedstocks as substitutes for petroleum-derived raw materials, thereby addressing growing environmental and regulatory pressures. Mastery of these new production routes represents a decisive competitive advantage for industrial players and Vinci has accumulated a lot of experience and customer feedback on these research topics. 

However, monomer synthesis projects are characterized by a particularly high level of confidentiality. The monomer production process is often regarded as a strategic asset, as it directly determines the producer’s economic and technological competitiveness. As a result, such processes are rarely shared and remain strongly protected, including from technology partners or pilot unit suppliers.

Representative examples of polymerisation pilot plans are provided in the following datasheets. In these projects, innovation focuses on multi-stage synthesis—via new catalysts, operating conditions, or feedstocks—making confidentiality a key requirement to preserve competitive advantage. Over the years, Vinci focused on the design of fluidized beds for the synthesis of polypropylene, HDPE and LLDPE and the design of slurry and loop reactors which can also be used for depolymerization. Pilot results were shown to match MI and density of PE attained in industrial HDPE and LLDPE plants.
