Pyrolysis Waste Water to Become Useful

Carbonization processes such as pyrolysis and hydrothermal carbonization (HTC) expected to fulfil important roles in future bio-refinery concepts. However, until now a major problem is: These processes form waste waters that contain various environmental hazardous substances. Researchers in Potsdam/Germany seem to crack it.

Migration with a Vision: How to Update a Whole Refinery in Only Two Weeks

Refinery modernizes safety systems in just two weeks and assures plant availability for the future—In September 2014, the German refinery Heide Refinery used two weeks of planned downtime at its pyrolysis plant to migrate to new safety systems. The technology selection emphasized plant availability and a high level of investment security, while extensive preliminary testing guaranteed a smooth changeover.
