| Abstract: | The causes decreasing crude phenol production and recovery have been found, such as big fluctuation of scrubbing operation, low separation efficiency of decomposer column and high phenol content in tail gas, etc. by analyzing crude phenol production and CO2 decomposition. Solutions are given for improvement, such as improving scrubbing operation, adjusting decomposer column process, improving tail gas precipitation and increasing spent lye extraction, etc., so that the crude phenol pro- duction and recovery can be upgraded. |
