Abstract [en]

In this work an assessment of the compressed air system in the facilities of Vattenfall Heat Uppsala has been conducted. The facilities constitutes, among others, a combined heat and power plant, and two waste incineration plants. The compressed air is supplied primarily by seven rotary screw compressors and yearly electric energy consumption in these has been determined. Furthermore, the usage of compressed air has been mapped in order to find processes with energy savings potential. Several suggestions how to reduce the usage of compressed air have been presented, resulting in decreased need of electric energy and reduced CO2-emissions.

The results show that total need of electric energy in the compressors, during a standard production year, amounts to 5.83 GWh. The proposed process changes, if all of them are implemented, will save around 1 GWh/year. The reduced energy usage results in a financial gain of roughly 600 kSEK/year and about 400 tonnes of CO2-emissions can be avoided.
