Simulation Tools and Advanced Process Control

An increasing amount of incorporated polar comonomers such as vinylacetate leads to reduced crystallinity combined with improved low-temperature properties, improved toughness and flexibility, improved impact strength, and reduced flexural modulus (stiffness). Typical applications for EVA grades include footwear, films, hot melt adhesives, and wire and cable. The improved low temperature properties are utilized in, for example, deep-freeze bags. 

Compared to other polymer production processes and even among polyolefin processes, the high-pressure LDPE production technology is highly suitable for 

the radical polymerization kinetics is well known and has been extensively studied in the past and continuously updated. The kinetics of oxygen and peroxide initiation are relatively easy to be determined experimentally. 

In this chapter, the focus is on practical model applications in an industry aimingto increase production rates, narrow specification ranges, accelerate grade transitions, reduce specific operating costs, and improve scale-up. 

Various commercial software packages are used industrially that ease the computational burden.
