| titleOfInvention | A method for separating by-products in the process of methanol carbonylation to methyl formate |
| abstract | The invention discloses a method for separating by-products in the process of producing methyl formate by methanol carbonylation, comprising: the product after the methanol carbonylation reaction enters a gas-liquid separation tank (5) to flash CO gas, and the liquid phase undergoes methyl ester rectification The tower (7) separates methanol and methyl ester; part of the bottom of the methyl ester rectification tower (7) is cooled and returned to the dry methanol storage tank (1) for recycling, and the other part enters the thin film evaporator (10) for concentration and separation, and part of the solid Phase and methanol enter the raffinate crystallization tank (11) through gravity flow, and then send it to the decanter centrifuge (12) for solid-liquid separation. The solid salt is discharged from the slag discharge port of the decanter centrifuge (12), and the liquid enters the disc centrifuge. centrifuge (13) for further separation, the liquid after passing through the disc centrifuge (13) is returned to the dry methanol storage tank 1 for recycling, and the solid-liquid salt is discharged from the slag outlet of the disc centrifuge (13). The invention has good desalting effect, high degree of automation, less loss of methanol and low environmental risk. |
