For owners of oil heating systems who want to contribute to climate protection with renewable energies, greenhouse gas-reduced paraffinic heating oils are an option in addition to the integration of solar energy. But can a fresh, purely paraffinic heating oil be refueled on top of a residual quantity of mineral oil-based heating oil that has been stored for years?
In a current project, OWI Science4Fuels gGmbH and the Institute of Plastics Processing are investigating the compatibility of paraffinic fuels with plastics commonly used for tanks and fuel-carrying fittings of oil heating systems. In particular, the focus is on the effect in existing consumption plants for heating oil. The interaction with the tank materials polyethylene (PE) and polyamide (PA), with protective film made of polyvinyl chloride (PVC), with seals made of elastomers and with other polymers used in fittings is investigated.
Many owners of new and older oil-fired heating systems would like to heat in a climate-friendly way. In a current research project, OWI Science for Fuels gGmbH and the Chair of Analytical Chemistry at the Institute of Chemistry at the University of Rostock are investigating what proportions of new low-greenhouse gas alternative fuels can be safely added to older heating systems.
