OREANDA-NEWS. February 15, 2008. In the by-product recovery plant №1 at “Koks” public corporation the reconstruction of sedimentation plant is carried out. At the present time the work is underway on the four “round” tar decanters, which volume is 650 cubic meters. They have been in operation since 1979 and periodically need labour-intensive repair with great material expenses. In the context of reconstruction old-fashioned tar decanters are replaced by more efficient and reliable ones, so called “ships”, which volume is 380 cubic metres. In the nearest future the tar decanter №6 will be dismantled, owing to this fact the roadway will be widen. In May the first “round” tar decanter is intended to be dismantled and on its place the two new ones will be mounted, each having the volume of 380 cubic metres.
