Question 2 (Answer all parts, 48 marks) Figure 1 shows the P&ID for an agitated vacuum filter dryer along with some associated systems. The equipment is to be used to dry a finely divided, combustible, organic solid powder with low toxicity and with a low minimum ignition energy. Previous published studies have shown that the product can be dried safely and in an acceptable time operating with an absolute pressure of 50 mbar and limiting the maximum powder temperature to 40 °C. The particulate material is transferred into the filter dryer in suspension in a medium volatility, highly flammable, non-conductive solvent. The wet filter cake is washed using the same solvent, most of which is removed at the end of the filtration step. Focus your answers on the drying phase of the process. (a) Identify and explain three attributes of the materials being processed which present a hazard in terms of the potential for a fire or explosion.
Agitator motor with variable speed drive; pitched agitator blade can be raised and lowered, rotates clockwise to dig & discharge the filter cake, counter clockwise to smooth the cake surface.
