PROCESS FOR THE PREPARATION OF ETHYLENE GLYCOL |
| 摘要 |
The invention provides a process for the production of ethylene glycol from ethylene. An ethylene glycol stream comprises inorganic chloride contaminants and the process comprises steps of converting the inorganic chloride contaminants to 2-chloroethanol by reaction with ethylene oxide in one or more dehydration columns, and removing 2-chloroethanol in a waste water stream. |
