Upgrading of Lignite to Clean Coal Briquettes

Target

• Smokeless briquettes
• Invcreasing the heating value
• Drying
• Reducing of sulphur
• Preparing for briquetting
• Getting smaller amounts of (heating) oils

Products Permanent gas: for self-heating of process (autotherm) Condensate oil: different qualities after destillation or refining Condensate water: Solids: briquettes

(heat for app. 2-3 h)

Advantages DGE Basic Technology

• continuous process for highest quality and stability
• no critical emissions
• producing of sulphur reduced coke
• lower amounts of process gas than conventional cokery technologies
• relativ small plants for decentral operation near outlying mines
• same plant for lignite processing, waste disposal, tyres disposal, oil contaminated soil cleaning

Needed Pre Treatment

• Drying: 10% WC is requiered
• Crushing: max. grain size 10mm
• Sorting: not needed

Post Treatment by Partners

• Briquetting
• Destillation or refining of oil condensate
• Cleaning by fermentation of condensate water
