Pharmaceutical Powder Screening
The client required a small scale laboratory test apparatus which could screen their manufactured pharmaceutical products for magnitude of explosion effects (i.e. maximum pressure and maximum rate of pressure rise) when ignited as a dust cloud. They also had insufficient powders available for 20ltr sphere testing.
Solution: A Hartmann Bomb apparatus based on a 1.2 litre volume Hartmann tube. Whilst realising that the Hartmann Bomb data must not be applied to Process Plant as a basis for safety, the benefit of this apparatus was that only a very small quantity of sample was required for each test.
Because the client wished to make maximum pressure rate comparisons between their various manufactured products, the equipment supplied provided a very useful screening tool. A high speed data acquisition software and hardware solution was provided together with the dispersion and igniter firing electronics.
