| titleOfInvention | A system and method for recovering and refining the by-product methyl formate in the coal-to-ethylene glycol process |
| abstract | The invention relates to a system for recovering and refining the by-product methyl formate in the coal-to-ethylene glycol process, comprising an MN stripping tower, the bottom of the MN stripping tower is connected to the feed inlet in the middle of the MF separation tower through a pipeline, The top of the MF separation tower is communicated with the first condenser, the first reflux tank and the inlet of the middle part of the MN separation tower through pipelines, and the top of the MN separation tower is connected with the second condenser and the second reflux through pipelines. The tanks are connected in sequence, and the bottom of the MN separation tower is connected with the crude MF storage tank through a pipeline. The invention is a high-quality standard methyl formate product, and effectively solves the problem of operational safety caused by high-concentration accumulation of methyl nitrite at the top of a rectification tower in the methyl formate by-product of coal-based ethylene glycol. |
