| titleOfInvention | METHOD FOR PROCESSING LIQUID FLOW AFTER HYDROFORMING |
| abstract | 1. A method of processing a liquid stream leaving a hydroformylation reaction that contains an aldehyde, high boiling point by-products of a hydroformylation reaction, a homogeneously dissolved rhodium complex catalyst, an unreacted olefinically unsaturated compound, synthesis gas and volatile by-products, in which a) a liquid stream is throttled after hydroformylation in the expansion tank, and there is a separation into the liquid phase and the gas phase, b) the liquid phase obtained in the expansion tank according to give to the separation device, in which there is separation into a liquid phase, which mainly contains high-boiling by-products of the hydroformylation reaction, a homogeneously dissolved rhodium complex catalyst and a small amount of aldehyde, and a gas phase that contains the vast majority of the aldehyde; and c) a liquid rhodium-containing stream is taken from the separation device, characterized in that the liquid rhodium-containing stream selected from the separation device is passed through a filter, and the solids separated therefrom are removed from the process, while the obtained filtrate is returned to the hydroformylation reaction. 2. The method according to claim 1, characterized in that part of the selected from the separation device liquid rhodium-containing output stream is removed from the process, and the other part is passed through a filter. The method according to claim 1 or 2, characterized in that the separation device operates at a temperature of up to 160 ° C, preferably from 100 to 140 ° C. The method according to claim 1 or 2, characterized in that the partial pressure of carbon monoxide is set in the gas phase of the expansion tank |
