Coal-drying technology

RWE researched and developed an efficient lignite drying technology, called WTA™ technology, which dries lignite from more than 65% to 10% moisture. The first commercial-sized WTA drying plant with evaporation heat recovery was commissioned in 2009 at RWE’s Niederaußem power plant.

Our WTA-related services include:

Opportunity studies
Laboratory scale tests
Industrial scale-drying tests
Basic design of WTA plants

In addition, we support the RWE-approved suppliers during detail engineering, construction and commissioning of WTA plants and in training of operating staff.

Ash reduction technology

Dry ash separation technology has become a real alternative to regular (wet) coal washing for specific cases. Our services comprise the following:

Opportunity and feasibility studies
Complete flow sheet development
Troubleshooting and optimising in/of processing plants
Laboratory and pilot plant tests
