Example 2.4 Selection of system boundaries and organisation of the solution. The diagram shows the main steps in a process for producing a polymer. From the following data, calculate the stream flows for a production rate of 10,000 kg/h. Reactor, yield on polymer 100 per cent slurry polymerisation 20 per cent monomer/water conversion 90 per cent catalyst 1 kg/1000 kg monomer short stopping agent 0.5 kg/1000 kg unreacted monomer Filter, wash water approx. 1 kg/1 kg polymer Recovery column, yield 98 per cent (percentage recovered) Dryer, feed ~5 per cent water, product specification 0.5 per cent H2O Polymer losses in filter and dryer per cent Short stop Monomer water catalyst fo Polymer Filter Dryer Reactor Recycle monomer Recovery column Effluent
