Decentralised portable containerised plant for the production of biodiesel in Nemsdorf-Göhrendorf

Decentralised portable containerised plant for the production of biodiesel in Nemsdorf-Göhrendorf Agitated vessel PLC Mixing vessel

Decentralised portable containerised plant for the production of biodiesel in Nemsdorf-Göhrendorf The process  Pure batch process, batch-type re-esterification (8 h)  All process steps in succession in a single vessel.  A heatable agitated vessel is the core item of the plant.  Continuous process control through data logging.  Ensures reproducible process.  Plant trouble is detected at any rate.  Process is automatically interrupted.

Staff cost:  Only for management of raw and materials and auxiliaries. Energy consumption:  During 60% of the time no operation of any plant component (settling processes). Maintenance: Only one single vessel  less pumping / reduced no. of valve operation processes  low maintenance cost. Investment cost: Low space requirements through container solution offered  no expensive structural investment cost. Side products: No waste  No expensive disposal.  Raw glycerine and wash water as co-substrate in biogas plant.  complete energetic use of bio raw materials fed.

The decentral re-esterification Producing your own biodiesel - Small-scale plant for the agriculture  The owner/operator is also the producer of raw materials.  Own farming of rapeseeds as regenerative raw material.  Local pressing and storage of rapeseed oil.  Use of presscake in own farm operations.  Use of biodiesel in vehicles of own farm and marketing locally and in the vicinity.  Use of glycerine and wash water as co-substrate in own or nearby biogas plant. -

The decentral re-esterification Producing your own biodiesel - Small-scale plant for the agriculture  Established closed cycles.  Shortens transport chains.  Creates jobs in rural areas.  Ensures that value is created locally.  Creates additional sources of income in agriculture.  Makes the producer more independent of the market.
