Balancing the Water and Chemical Balances at the Pulp Mill

摘要

The softwood pulp mill processes were simulated by the RAMI simulation program.The chemicals were balanced during simulation runs. The modelled 1,000 ADt/d fiber line consists of modern but proven and effective processes with circulations. The 'Ecologically balanced' kraft pulp mill concept, workname 'RAPEA' is suitable for implementing using computer aided control and on-line analyzers, which makes it possible to control the entire pulp mill if desired from the one station. The fully bleached softwood ECF-pulp can be produced economically and with improved allowed effluent quality.
