Abstract
An increased energy supply is required in connection with a planned expansion of Braviken paper mill. An operational study in which data relating to the flows in the plant were compiled, and the possibility of increasing efficiency was investigated with the aid of pinch analysis. Futhermore, alternative technologies for combined heat and power production, and environmental requirements and consequences were investigated. The pinch analysis shows that in two operational cases there is a theoretical potential for increased energy production of at most about 9.5 and 11.7 MW{sub th} respectively. The efficiency increases correspond to 20-25% of the steam produced in the steam power plant. The analysis shows that with expanded paper production an industry plant with a new LPG-fired gas turbine, a new waste heat boiler, a new solid fuel boiler (CFB), a new fuel drier as well as an existing steam turbine, some 150 GWh{sub el} per year could be produced at a cost of 200 SEK per MWh{sub el}. The production of electricity in the steam and gas turbine is then limited to 5840 h per year since the marginal cost of operating the turbines during the summer months is too high. However, other parts of the CHP-plant

Emissions of sulphur and nitric oxides are low compared with emissions from other manufacturers of TMP/newsprint. Calculations in respect of the various CHP alternatives are given in the report. The total emissions of sulphur, nitric oxides and dust from the production of electricity and heat by the CHP-plant will be lower than those from the reference cases producing only heat. By investing in an expansion of paper production Holmen can obtain an interesting price for the heat and produce electricity at a competitive cost in relation to other forms of electricity production. Prospects similar to those at Braviken could also exist where other pulp and paper manufacturers are concerned.}
