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, as the control performance has actually improved under the watchful, remote surveillance of Valmet engineers, As an example, Valmet staff have been instrumental in diagnosing and correcting a temperature regulation problem. Valmet’s solution reduced chemical consumption.
Through 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 experienced engineers can diagnose and make recommendations about how to correct a problem and improve the results of the controls. The bleaching process performance is monitored stage by stage and regular control performance reports are provided to the customer. Mr. 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. Mr. Pierre Carnevali, projects manager, adds, “The reports tell us if we are in a good control range or not and if we are consuming the right amount of chemicals.”
