Gasification is a process for converting solid carbonaceous materials (coal, petroleum coke, biomass, municipal waste, wood chips, car tyres, etc.) into combustible gases. Various filtration stages are involved throughout this industrial process, which takes place at high temperature and in a reducing atmosphere.

Petrochemical industries use highly specialised filters to process chemically aggressive compounds, which are often highly viscous and maintained at high temperatures. Depending on the sector, the fluids requiring filtration vary greatly: oils, fuels, gases, as well as water and solvents. In oil refineries, the purity of the produced fuel is crucial.

The production of fuels or polymers involves the use of industrial filters with a wide range of characteristics, which have to comply with strict regulatory standards in terms of safety and the environment. From upstream to downstream in the production chain, we need to be able to filter very different liquid and gaseous substances.
