Ethylene composites

Using this equation, My. can be calculated for a given ethylene composition at each elution volume similarly, fF(lnM ) and h Vi). The average ethylene composition of the copolymer eluted at F can be determined, and hence the variation in composition as a function of elution volume over the whole range.

The production of ethylene by dehydration of ethanol is a proven technology and was demonstrated and implanented on large scale (Winter, 1976). Braskem started a full-scale plant in Brazil in 2010 (Braskem, 2012). The process consists of a dehydration reactor and several subsequent purification steps in order to obtain polymer-grade ethylene (composition 99.95 wt% ethylene, 0.05 wt% ethane, 5ppm CO and lOppm CO (Kochar et al., 1981)). Figure 4.6 iUustrates the ethanol dehydration process investigated in this study and lists the input data used for process simulation.
