Electric motors in continuous or near-continuous service have high energy costs, even at the relatively low electric rates common in much of the chemical industry. Don't squander savings opportunities when considering motor replacement
All materials and processes have multiple hazards. However, it is highly unlikely that any alternative process will be inherently safer with respect to all hazards. So, optimization efforts must focus on identifying the design that gives the best overall combination of desirable characteristics.
