  7. 3B - Diesel GmbH www.3b-diesel.de email: d.kieser@3b-diesel.de Decentralised portable containerised plant for the production of biodieselinNemsdorf-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.

  8. 3B - Diesel GmbH www.3b-diesel.de email: d.kieser@3b-diesel.de 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.

  12. 3B - Diesel GmbH www.3b-diesel.de email: d.kieser@3b-diesel.de • 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. -

  13. 3B - Diesel GmbH www.3b-diesel.de email: d.kieser@3b-diesel.de • 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 independentof the market.
