Combined Heat and Power in Chemical RecoveryCosts & Benefits
|Parent Process: Chemical Recovery|
|Energy Savings Potential||
While in conventional power plants only less than 40% of the energy input is converted into electricity – and the rest of the energy is wasted –in cogeneration facilities 80-93% of the energy input is converted into 40-70% heat and 20-45% electricity.
|CO2 Emission Reduction Potential||
The CHP can reduce CO2 release rate by 50% compared to conventional power generation systems (BREF, 2010. p. 542).
The specific investment cost for transforming existing steam back-pressure units into combined cycle cogeneration plants is estimated to be EUR 1000/kW. The achievable savings and the payback time depend mainly on the price of electricity and fuels within the country.
