Mayr-Melnhof Graphia Project

Izmir - Turkey

Project description

The thermal energy supply of the cardboard production plant in Izmir, Turkey by the Austrian company Mayr Melnhof Graphia was previously implemented 100% using fossil fuels. The system was heated by burning natural gas and required 1,200 kW boiler output. In addition, the system required approx. 3000 kW to drive 2 compression refrigeration machines, which were necessary for both process and room cooling. The energy concept implemented by the SOLITERM Group has made it possible to cover around 80% of the thermal energy requirements of the system in summer and a significant proportion (60%) in winter with environmentally friendly and CO2-free solar thermal energy.
As part of the project, a total of 500 parabolic trough collectors (approx. 4,500 m2 net area) will be installed worldwide, the largest system of this type, which will concentrate the sun’s rays on absorbers in the middle of the collectors. The hot water 170-180 ° C (PN16) obtained in this way is converted into cold in a two-stage absorption chiller and excess energy is stored in a storage tank (high-temperature storage), so that the energy requirements of the system are covered by solar thermal energy, even during the night or on sunny days can be. As a result, the excess radiation energy is not lost, but is made usable. With the help of a heat exchanger and other components, the energy is transferred to the secondary circuit, which is then responsible for heating the production facility. In summer, an average of 3,000 kW (3,500 kW peak) of usable solar cooling is provided. If the stored solar heat is not sufficient for night-time operation in summer operation, the necessary additional heat is provided by a boiler; this also applies to winter operation. The solar coverage of the thermal energy demand of the Mayr Melnhof Graphia production plant achieved through this project amounts to 80% of electricity consumption in summer and an average of 60% natural gas consumption in winter.

Annual energy savings achieved

Natural gas: 1,615 MWh / a, electricity: 3980 MWh / a

Percentage annual energy savings

When generating cooling: approx. 80%
When generating heat: approx. 60%

In relation to the total energy consumption of all energy consumers (there are other energy consumers besides cold and heat) in the factory: approx. 30.74% / year

Emissions saved annually

3,040 tons of CO2 (equivalent) / year

German Energy Agency

Dena is the centre of expertise for energy efficiency, renewable energy sources and intelligent energy systems. As Agency for Applied Energy Transition we help achieve energy and climate policy objectives by developing solutions and putting them into practice, both nationally and internationally. In order to do this, we bring partners from poli-tics and business together, across sectors. Dena’s shareholders are the Federal Republic of Germany and the KfW Group.

German Energy Solutions Initiative

The transfer of energy expertise, the promotion of foreign trade and the facilitation of international development cooperation are part of the German Energy Solutions Initiative, which is coordinated and financed by the German Federal Ministry for Economic Affairs and Energy. The initiative offers networking and business opportunities in Ger-many and abroad, it showcases reference projects and facilitates capacity building.

Renewable Energy Solutions Programme (RES Programme)

With the RES Programme, the Deutsche Energie-Agentur (dena) – the German Energy Agency – helps German renew-able energy companies enter new markets. The installation of climate-friendly energy technology projects in attrac-tive target markets is accompanied by comprehensive information dissemination, marketing and training pro-grammes. These flagship projects, supported by the Federal Ministry for Economic Affairs and Energy within the German Energy Solutions Initiative, aim to show-case high-quality German renewable energy technology and help participating companies gain a foothold in new markets.
