CUSTOMER’S VOICE
Serving our customers with Industrial Internet
Virtual connection, remote diagnosis add to Burgo mill results A Valmet bleach plant optimization project at Burgo’s Ardennes kraft pulp mill in Belgium achieved the customer’s expectations and a good ROI. However, this was not the end of the task to maintain and improve the results. e control performance has actually improved under the watchful, re- mote surveillance of Valmet engineers. As an example, Valmet staff has diagnosed and corrected a temperature regulation problem. Valmet’s solution reduced the chemical consumption. rough daily and monthly reporting and proactive follow-up, control solutions continue over the long term. A Performance Service Agreement includes remote system and process monitoring though a data link to Valmet which includes refined key process indicators (KPIs) and performance triggers. As a result, the Burgo process is virtually 24/7 in Valmet offices where the process performance is analyzed and diagnosed and recommendations can be made about how to correct a problem and improve the results of the controls. e bleaching process performance is monitored stage by stage and regular control performance reports are provided to the customer. Eric Bazzoni , fiber line production manager, finds this a useful tool as it gives a concise report on key control objectives and uncovers any problems. Pierre Carnevali , projects manager, adds: “e reports tell us if we are in a good control range or not, and if we are consuming the right amount of chemicals.”
Possibility to use more biomass fuels Kuopion Energia Oy produces district heat for the residents of the city of Kuopio in Finland, thus the production reliability is in high priority. ey have had Valmet’s FuelDiet KCL corrosion control system in use since 2013 at their Haapaniemi 3 power plant. e FuelDiet solution enables to use more biomass fuel without increasing the risk of superheater corrosion. Jaani Silvennoinen , Valmet’s Product Manag- er for FuelDiet explains: “With the performance agreement and remote connection, we can give stability to the customer’s energy production pro- cess. As a result, they can now use 100% biomass and get real time measurement of the sulfur/chlo- rine ratio and hence react immediately if the ratio goes too low. Automatic control helps and guides the operator to run the power plant optimally and they have been able to increase the boiler’s maximum load.”
Industrial internet supports process improvement at CMPC Guaíba
“e remote access to the DCS and mill data has always to be agreed with the client, due to se- curity reasons, but it has shown to be a powerful tool to support cus- tomer operations whenever upset conditions take place. It allows us to provide fast support even during the night or when the problem can’t wait for a process engineer to travel to the site. It allows us also to analyze historical data to better understand the changes in process conditions along the time and find ways to further improve the plant”, says Dimas Rodrigues , Valmet’s process manager.
In 2013, when Valmet and CMPC signed a contract to supply the main technology to Line 2 at CMPC’s Guaíba Mill in Brazil, the delivery included a major part of automation systems for the plant operations, such as Distributed control systems (DCS), Operation training simulator (OTS) and Ad- vanced process control (APC). Embedded in this supply, Valmet delivery also included the possibil- ity to remote access to operation data, allowing process improve- ment and system check-outs even when Valmet crew are not physical- ly at the mill.
