| titleOfInvention | Method for recovery of glyphosate solvent and by-products |
| abstract | The invention relates to a method for recovering glyphosate solvent and by-products. The methanol vapor is used as a heat source for the reboiler of a light component refining tower and the reboiler of a methanol refining tower after being pressurized to increase the energy grade. The use of heat replaces the use of low-pressure or medium-pressure steam, and the device does not need to consume raw steam during normal operation, which greatly reduces the energy consumption of the process and achieves the purpose of energy saving and consumption reduction. The condensation temperature of the light component is increased, so that the top discharge of the pre-rectification tower and the light component refining tower can be cooled by cooling water, avoiding the use of higher-cost frozen brine, reducing the production cost and improving the process efficiency. Economical; and the method has strong separation ability for each component, high recovery rate, high purity and good quality of methanol and by-products methylal and methyl chloride, and can be applied in industry. |
