Apr 03, 2012. /Lesprom Network/. As part of implementation of the Big Bratsk Project, installation of new superconcentrators at the evaporation station was completed and a test run was carried out. The superconcentrators will be put into semi-commercial operation in the near future. Test run of the superconcentrators marked the beginning of Big Bratsk equipment start-up, as the company said in a press release received by Lesprom Network. During the start-up of the new equipment, experts from the Bratsk mill (Russia) tested all constituent elements of superconcentrators: pumps, actuators, control and lock valves. Following the start-up of new superconcentrators, two old concentrators will be rebuilt. Installation of new modern superconcentrators will increase liquor concentration before burning up to 75%, thus allowing to reduce emissions.
