What should be taken into account during production, conveying and usege
Due to the importance of ethanol for cleaning agents, bioethanol is also currently at the center of attention. But how does the manufacturing work, and what must be taken into account for the use and delivery of the medium?
Ethanol can also be produced from residual matters using biotechnology.
Everybody is talking about electromobility – but renewable mobility is currently being dominated on a much larger scale by biofuels. These are partially gaseous, but mostly liquid fuels that are produced from renewable raw materials. Besides plants grown particularly for the purpose of extracting fuels, these can also be waste, such as scrap wood. Methods for extracting ethanol from different agricultural residual materials are tested on a pilot scale: They avoid the “food or fuel” discussion, for example, by relying on straw as the source material.
Biofuel trumps e-mobility
At the present time, almost 25 million metric tons of biodiesel are produced worldwide from regenerative raw materials every year. This volume is surpassed by bioethanol: On an international level, the fuel reaches over 70 million metric tons in annual production volume. In Germany, ethanol sales amount to 1.2 million metric tons, of which roughly 700,000 metric tons are produced domestically. Depending on the property of the motor and the remaining technology, vehicles can be operated with fuels consisting of 100% bioethanol, or with an additive – the best-known example is E10. Gasoline contains up to 10% bioethanol.
The suitability of machine and infrastructure must be taken into account at all steps of the bioethanol production. Many drivers remember the question that made its rounds with the introduction of E10 in Germany, namely which vehicle could handle the blending. This question made its rounds because the alcohol contained in E10 can trigger a corrosion in components of the fuel supply that are made of aluminum and can also attack plastics, which may be used in hoses and gaskets.
Compatibility must be ensured
What applies to the use as a fuel also applies to the delivery, processing and storage. All machines and installations, in which ethanol is used as a medium, must be suitable for any contact with alcohol – especially in case of higher purity than the 10%, which is customary for fuel. This also applies to pumps: All parts in contact with the medium must tolerate the constant contact. On top of that, it may also be necessary to meet ATEX guidelines under certain circumstances.
Rapeseed is a popular raw material used for the production of bioethanol.
The selection of the corresponding materials handling technology that matches the medium and the production environment can pose challenges, even for experienced users.
