| titleOfInvention | Treatment device for rectifying still liquid in process of producing propionaldehyde through ethylene hydroformylation |
| abstract | The utility model provides a treatment device of rectifying still liquid in a process for producing propionaldehyde by ethylene hydroformylation, which comprises an input pump, a buffer tank, a preheating tank, a distillation tower, a condenser, a reflux tank, a lead-out pump, a sand filter and an oil-water separator, wherein the input pump is connected to the inlet of the buffer tank, the outlet of the buffer tank is connected with the preheating tank, the outlet of the preheating tank is connected with the inlet of the distillation tower, the gas-phase outlet of the distillation tower is connected with the inlet of the condenser, the outlet of the condenser is connected with the reflux tank, the outlet of the reflux tank is connected with the lead-out pump, the bottom of the distillation tower is connected with the oil-water separator, the oil-phase outlet of the oil-water separator is connected with the sand filter, the design solves the problem that the rectifying still liquid is inconvenient to separate and extract harmful organic matters in the prior process of producing propionaldehyde by ethylene hydroformylation, and the utility model has reasonable structure, so that the harmful organic matters in the rectifying still liquid are classified and extracted to achieve harmless discharge. |
