POLYOLEFINS: Condensed Mode Cooling for Ethylene Polymerization: The Influence of the Heat of Sorption

POLYOLEFINS: Condensed Mode Cooling for Ethylene Polymerization: The Influence of the Heat of Sorption

Arash Alizadeh and Timothy F. L. McKenna*

The relative importance of the higher solubility of n-hexane and its associated heat of sorption on the thermal behavior of the polymer particles during gas phase ethylene polymerization is investigated. It is found that if a polymerizing particle begins to heat-up, the partial desorption of a condensable solute in a gaseous state helps to attenuate the temperature rise in the polymer particles, decreasing the risk of local hot spots.
