Fluids treated by Barriquand heat exchangers

Fluids treated by Barriquand heat exchangers
Barriquand proposes different heat exchanger solutions for fiber-laden fluids, according to the type of fluid and the space available.
  • Filtrate/filtrate
  • Black liquor: Barriquand heat exchangers recover energy from the black liquor (produced by the burning of fibers) for re-use.
  • Back water: Barriquand heat exchangers are used to heat and cool the paper wash waters in order to reach the setpoint temperature. 
  • Effluents: Paper mills must comply with legislation that requires their waste water to be treated in a purification plant before being discharged into the natural environment at a temperature below 30°C.
  • The operator can save money by recovering heat from the effluents before discharge (even below 30°C).

Other exchanger applications in pulp and paper industry

  • Heat exchangers on utility fluids
  • Production of hot water
  • Fuel heaters (natural gas, heavy fuel oil)
  • Kettle (evaporator-condenser, heat transfer oil, superheated water, etc.)
  • Heat exchangers for waste water treatment plant
