Site Selection And Plant Layout For Acetone Production

The continuing need for acetone production led to the scale-up of the Weizmann process to a 7,000 gallon scale at a plant in the Naval Cordite site in Holton Heath, Dorset, in early 1916. This move was not immediately successful as seven out of ten fermentations were failures and discharged onto the neighbouring heath – much to the ...
