| Abstract: | The fast circulation phenomenon appeared in esterification reactor of DuPont esterification process was expounded and analyzed.It was explained that the occurence of fast circulation was due to the critical situation of process condition.The change of PTA raw material and process parameters lead to the fast circulation phenomenon.The probability of fast circulation can be reduced by optimizing the process parameters according to the raw material. |
