Coal Dust Suppression

Patented dust control and anti-oxidant solutions from mine to power plant

CoalPlus* is an engineering blend of anti-oxidants, binders and foam suppression technology designed to mitigate unique handling issues associated with use of sub-bituminous coals and other reactive solid fuels. CoalPlus treatment is typically applied at mine sites to reap maximum benefit from mine loadout to power plant delivery.

Veolia’s CoalPlus* Treatment Program

Veolia has developed a unique program of patented anti-oxidants, dust control binders and high-performance foam application systems to “body feed” the anti-oxidants and binders to PRB and other subbituminous coals at the mine site  – prior to loading into the rail cars or barges. 

Veolia’s CoalPlus technology retards the oxidation and weathering of low rank coals, which in turn reduces hot spots, smoker and spontaneous combustion at mines, coal terminals and at generating stations.

Binding Agents

DusTreat* Binding Agents

DusTreat binding agents are patented dust control technologies designed to reduce fugitive dust emissions and inhibit the surface oxidation of low rank coals.

DusTreat binding agents combine the functionality of a long-term residual dust control binder, with an anti-oxidant capability. DusTreat binders prevent dusting by two mechanisms – by agglomerating the fine particles as a binder and by reducing the weathering of the coal. 

DusTreat Binding Agents Features & Benefits

  • Reduces dusting during loading, unloading, stack-out and reclamation
  • Reduces in-transit coal losses from rail cars – may eliminate need for car topper treatments
  • Retards the oxidation and weathering of low rank coals, such as Powder River Basin (PRB) coals
  • Significantly reduces hot spots, smokers and spontaneous combustion at generating stations and coal terminals
  • Reduces BTU or calorific losses during storage at coal yards and terminals

Foaming Agents

DusTreat* Foaming Agents

The DusTreat foaming agents are formulated to produce resilient, low surface tension foam to control fugitive dust throughout the mine, terminal, or power plant material handling system. In addition, when combined with DusTreat Binding agents they control dust on active storage piles and during reclaim operations.

DusTreat foaming agents offer the best available technology by providing effective dust control while minimizing moisture addition to the coal or other solid fuel. 

DusTreat Foaming Agents Features & Benefits 

  • Provides residual control of fugitive emissions while minimizing moisture addition
  • Produces high expansion foam with most plant waters
  • Reduces maintenance and housekeeping costs
  • Reduces explosion hazards and improve working conditions
  • Improves worker health by reducing respirable dust emissions
  • Environmentally safe
