Process Improvement Options Estimated Savings

Scaled exergy input of the alternative extruder and regular extruder plotted against static mixer diameter. 

Alternative to extruder savings between 0.19 and 0.40MJ/kg PE, which gives a loss between 0.07 and 0.28MJ/kg PE compared to 0.47MJ/kg PE. 

Option 1 is not yet technologically viable but option 2 is. In the remainder of this chapter, we will continue to focus on the LDPE process from ethylene only.
