摘要: The Sanchez–Lacombe equation of state (SL EoS) was used to estimate the concentration ethylene and different induced condensing agents (ICAs) in polyethylene, effects adding an ICA on parameters such as reactor temperature, production rate, particle size were discussed. A simple continuous stirred tank (CSTR)-like model validated from data, results reveal that serious errors will be found prediction temperature rate if interaction between is not taken into account. It also shown can lead increased rates at cost decreased catalyst mileage.
