In its more than twenty-year history, ALITER-AXI has developed scientific, technological, design and production services which are able to deal with the issues of engineering, manufacturing, supply and installation of process equipment operating at high temperatures in different industries. The most considerable experience has been accumulated in oil refining and petrochemistry (fired heaters, reaction furnaces, combustion chambers, refractory linings of FCCU), aluminum smelting (linings for melting furnaces, mixers, and gutters), nitrogen industry (linings for primary and secondary reformers, manifolds and pipelines). We have developed multiple solutions regarding lining design and refractory applications in power engineering, incineration, cement industry, ferrous metallurgy, bricks and ceramics production. In these twenty years, we have accomplished and implemented more than two hundred projects of major repair, reconstruction and new construction of furnaces and furnace blocks at most oil refineries of the former USSR, in Bulgaria, Bosnia and Romania.
