Efficient use of industrial waste heat
Industrial waste heat is a by-product of many industrial processes and is currently often released into the environment unused. This applies in particular to high-temperature processes with process temperatures of more than 1,000 °C. The costs and CO2 emissions associated with the provision of energy represent a major burden for companies and the environment. In industry, the waste heat is already frequently used for heating other processes and for generating electricity or compressed air through direct recoupling. However, in many processes there is a time lag between the availability of waste heat and the demand for heat or electrical energy.
Diesel Fuel and Heating Oil
Diesel fuel and heating oil, which chemically belong to the middle distillate group, are subject to natural ageing during storage. The addition of alternative and biogenic liquid fuels to mineral oil-based middle distillates can accelerate the aging processes. For example, fatty acid methyl esters from regenerative raw materials promote the increased formation of sediments and acids as well as oxidation. The causes of sedimentation have not yet been fully explained. If fuels produced from different fossil and alternative raw material sources are mixed, effects occur which have not yet been sufficiently investigated.
