basic information
A case study of the introduction of an energy management and analysis tool based on a manufacturing execution system for the pulp and paper industry. Prior to the implementation, there were issues with reverse flow and costs associated with gas turbine full operation, steam, and boiler fuel. Therefore, it enabled demand forecasting for electricity and steam, achieved optimal operation of the cogeneration system, reduced the amount of electricity received, and lowered fuel costs for exhaust gas boilers and auxiliary boilers.
Applications/Examples of results
- Implementing Company: Manufacturing Industry (Pulp and Paper) - Implemented Products: MainGATE/PPA, MainGATE/MSPC [Challenges Before Implementation] - Power Reverse Flow Issue: Reverse flow occurs during full operation of gas turbines when demand decreases. - Waste of Steam: Release of surplus steam due to constant load operation. - Inefficient Fuel Consumption: Fuel loss during auxiliary boiler operation when steam is insufficient. [Effects After Implementation] - Annual cost reduction of 6 million yen due to reduction in received electricity consumption. - Annual cost reduction of 7 million yen due to reduced fuel costs for exhaust gas boilers. - Annual cost reduction of 8 million yen due to reduced fuel costs for auxiliary boilers.
