FIELD: chemistry.SUBSTANCE: installation comprises: sources of synthesis-gas and olefins, connected to reactor via purification devices, successively connected by means of pipelines with reactor input gas-liquid separator and evaporator, collector of bottom residue of which is connected with reverse pipeline of liquid recycle, with output of aldehydes from evaporator being collected with rectification column via collector-separator, as well as unit for discharge of waste catalyst and heavy reaction products. Installation is provided with sensor of liquid level, installed in collector of bottom residue; device for preparation of fresh catalyst solution, connected with reverse pipeline of liquid recycle and made in form of mixer with dosing device of catalyst components, with unit for discharge of waste catalyst and heavy reaction products being made in from of successively connected pump with device of its switching on and off, meter of liquid flow, device for distilling aldehydes from waste catalyst solution and connected with meter of liquid flow and dosing device of catalyst components of actuator, with output for aldehydes from device for their distillation from waste catalyst solution being connected with mixer of device for preparation of fresh catalyst solution, and sensor of liquid level is located with device of pump switching on and off.EFFECT: realisation of hydroformylation on claimed installation makes it possible to provide constant optimal quantity of heavy reaction products, optimal composition and quantity of catalyst solution.1 dwg, 1 ex |
