Heat Recovery from De-inking EffluentCosts & Benefits
|Parent Process: Recovered Fiber Pulping|
|Energy Savings Potential||
For a mill in the US having effluent streams at 49 °C and flow rate of 2.7 m3/min, the installation of a heat exchanger to recover heat and generate warm filtered shower for the mill's paper machines is estimated to reduce boiler fuel consumption by 39 000 GJ/y.
|CO2 Emission Reduction Potential|
Fuels savings for the boiler are estimated at $125,000/y. Capital costs had been $375,000 with a payback period of around 3 years.
