The Kraft plant in in Thurso produces specialized cellulose for, among other things, the textile manufacturing industry. The plant’s steam system consists of four pressure levels, a 24 MW cogeneration system and four boilers producing approximately 250 t/h of high-pressure steam. This process and its systems are very complex and require advanced data analysis techniques for energy management.
3E Eng. provided an expert in on-site data analysis and energy efficiency supported by three other experts to carry out the following mandates over a two-year period:
- Analysis of multivariate data from energy systems to identify causes of inefficiency
- Programming machine learning algorithms and energy management tools (control maps, tracking causes of inefficiency, Pareto diagram)
- Programming key performance indicators in Pi Process Book and Pi Asset Framework among other things
- Modelling of energy systems (on CADSIM Plus and Excel)
- Identification and implementation of energy-saving measures
- Setting up an energy management system ISO 50001
- Training an energy manager
All of the studies have identified more than 1M $/year opportunities to increase the profitability of the cogeneration system without investment.
