СOOO COTES Engineering professionals completed the project of automation of the water chemistry monitoring for boilers of Ust-Ilimsk Pulp and Paper Mill affiliated with OAO Ilim Group. Implementation of a novel system allows automatic water and steam sampling from various elevations of power generation boilers, as well as real-time analysis and displaying necessary parameters on the control panel. Automation of the chemistry monitoring allows considerable reduction of the human factor-induced errors and provides on-line monitoring of all critical parameters of boilers. COTES Engineering engineers have performed analysis and developed operating documentation which is approved by the industrial safety expert review and made cost estimates.
