OWI develops new measuring method
14 February 2020 –
In a current research project, the OWI Oel-Waerme-Institut wants to develop a new measuring method with which the process of manufacturing lubricating greases can be accelerated and thus become more cost-effective. The quality of lubricating greases depends to a large extent on the manufacturing process in which the grease constituents base oil and thickener should be homogeneously mixed. Determining the homogeneous distribution of the thickener during the development process is complex and expensive. With the new measuring method to be developed, the “time-to-market” and “cost-to-market” in the manufacturing process of the grease formulation should be reduced and the operational reliability of the grease in the later application should be ensured.
Newsletter offers overview of interim results
6 February 2020 –
In the EU project REDIFUEL the production of a renewable diesel biofuel is being researched, which is compatible (drop-in capable) with conventional fuels in any mixture ratio. After more than a year of research work, the current REDIFUEL newsletter offers an overview of the initial results. One of the numerous intermediate steps on the way to a drop-in capable product was the design of a distillation process to set a standard flash point of the REDIFUEL. The desired fuel must meet the quality requirements of standard EN 590 for diesel fuels with a flash point of at least 55 °C. To achieve this, an intermediate product must be distilled. This intermediate product contains, among other things, long-chain paraffins which lower the flash point and must therefore be separated in a distillation process. This process must be designed to avoid the separation of short-chain alcohols, which have a similar boiling range as long-chain paraffins, in order to maximize product yield.
Residual and waste materials as raw material basis
4 February 2020 – The use of biogenic residual and waste materials for the production of alternative heating oil could make the operation of oil heating systems more sustainable and climate-friendly. Secondary raw materials such as tall oil, grease separator residues or used frying oils could be used for this purpose. Through the production processes of hydrogenation and isomerisation, they acquire chemical-physical properties that are very similar to those of heating oil according to DIN 51603-1. This results in good combustion properties of these hydrogenated bio-oils, which enable their use in existing oil heating systems.
New Future Fuels blog provides information on renewable energy sources
30 January 2020 – The energy mix of the future will also include renewable fuels. But what is the potential of these energy sources, what is the state of research and development, where is the first practical experience already available and what opportunities does a global market – for example for Power-to-X – offer? These and many other questions are addressed in the recently launched futurefuels.blog.
09 January 2020 – The Zuse community continues to grow. With the accession of the OWI Oel-Waerme-Institut gGmbH from Herzogenrath near Aachen, the nationwide association of non-profit research institutes now unites 75 members, seven of them in Aachen and a total of twelve in North Rhine-Westphalia. The membership certificate was officially handed over on January 8 by Dr. Friedrich-Wilhelm Bolle from the Presidium of the Zuse Community. The OWI is a research institute that works on the further development of conventional and alternative fuels and innovative efficiency technologies in cooperation with partners from industry and research.
“Residue2Heat” workshop presented research results
20 December 2019 – In a public workshop held in mid-December 2019, the partners in the EU research project “Residue2Heat”, including the Oel-Waerme-Institute, presented the results of their research and development work. The aim of the project was to use different types of biomass residues for domestic heat production. The biomass residues are converted into fast pyrolysis bio-oil (FPBO), which is a 2nd generation biogenic fuel suitable for combustion in domestic heating systems. When FPBO is used, depending on the raw material used, between 77 and 95 % lower greenhouse gas emissions can be expected compared to conventional fuel oil.
New insights into the service life of metallic furnace components
12 December 2019 – A realistic service life calculation of components can help making the operation of industrial furnaces even more economical in the future. In a joint research project the Oel-Waerme-Institut, the Institut für Industrieofenbau und Wärmetechnik (IOB) of the RWTH Aachen and the Institut für Werkstoffkunde (IfW) of the Technische Universität Darmstadt have gained new important insights into this and implemented them in the development of a method for calculating service lifes. Manufacturers of industrial furnaces may use the research results for a more reliable design of furnace components. Plant operators will be able to more accurately determine the remaining service life of the components and thus to develop strategies for optimized furnace operation under economic aspects such as production throughput, service life and failure probability.
Invitation to an European Workshop
05 December 2019 – The consortium of the European research project “Residue2Heat” cordially invites interested experts to participate in an international workshop on the topic “Generation of space heating with renewable rapid pyrolysis bio-oil”. The workshop is the closing event of the research project “Residue2Heat – Renewable residential heating with fast pyrolysis bio-oil”, which was carried out within the framework of the EU research programme HORIZON 2020. It will take place on 11 December 2019 at the RWTH International Academy in Aachen.
Non-engine test procedure further developed
21 Oktober 2019 – Within the framework of a research project, the OWI Oel-Waerme-Institut gGmbH and the Institute for Energy Process Engineering and Chemical Engineering (IEC) of the Technische Universität Bergakademie Freiberg have gained important insights into the further development of a non-engine injector test rig including test cycle towards a fast, reliable and cost-effective test procedure for fuels and additives. The test bench is used to investigate and clarify malfunctions of diesel injectors caused by the formation of Internal Diesel Injector Deposits (IDID).
Greenhouse gas-neutral fuels
27 September 2019 – 150 experts from science and industry discussed the future of renewable fuels at the 3rd Technology Forum “New Liquid Energy Sources” on 26 September in Hamburg. In addition to presenting various production paths, the focus was on the future use of Future Fuels in mobility and heat supply.
