Abstract [sv]

I denna studie utförs energikartläggning av biogasanläggningen More Biogas. Anläggningens energiförbrukning kartläggs, sammanställs och visas i en modell konstruerad i Microsoft Excel. Genom att ändra frekvensen för komponenter kan modellen beräkna flöden och effektbehov i processen. För att utvärdera de resultat som modellen presenterar, testas modellen genom att anläggningens verkliga driftsituation efterliknas vid två separat tillfällen. Modellens resultat jämförs med den verkliga energiförbrukningen och avvikelser diskuteras. Ramarna för kartläggningen var att endast använda sig av enkla medel som går att hitta i de flesta verkstäder samt befintlig övervakningsutrustning.

 

Resultatet som presenterades av modellen gällande elförbrukningen hamnade cirka 17-25% under uppmätt elkonsumtion men då kartläggningen avgränsats i storlek är resultatet rimligt. Studien visar att energikartläggning är möjligt att utföra med enkla medel men för att avvikelser ska bli så små som möjligt krävs mer tid.

Abstract [en]

This study examines the energy consumption of the biogas production plant More Biogas. The energy usage of the facility is mapped, and the data is used to construct a model of the site in Microsoft Excel where flowrates and energy requirements are calculated based on set frequency of individual components. To see if the calculated result of the model can be considered valid, the model is tested by replicating the plants operation at two separate occasions. The result presented by the model is then compared to the actual measured energy consumption and the difference between the results is discussed. The boundaries for the mapping process was to only use the control system on site and simple tools that could be found in most workshops.

 

Results presented by the model concerning the electric power consumption fell short of the measured value by 17-25 % but because the energy mapping is limited in that it did not cover all the areas of the site, the results may still be considered valid. The study show that an energy mapping of an existing industrial process is possible with only simple tools but the task of making the results match real values as much as possible, requires more time.
