Emission data from EP-cleaned HPDC off-gas

This technique applies to existing installations. It is an end-of-pipe measure, applied in cases where prevention or minimisation of the mist has failed. Prevention and minimisation measures are discussed in Section 4.3.5.1. 

Minimisation of diffuse emissions and legislation on the emission of oil mist (e.g. in Sweden). Example plants 

General practice for older die-casting machines (D, F, B,.. . ) and for all die-casting machines in Italy. 

The capture and treatment of the off-gases of these process stages is generally possible for automated moulding and pouring installations. [29, Batz, 1986] 

Relative emissions (as kg/t of molten metal) increase over the pouring-cooling-shake-out sequence. Exhaust capture efforts will need to take this variation into consideration.
