RECOVERY METHOD FOR LIQUID CHEMICAL PRODUCT IN CHEMICAL PRODUCT MANUFACTURING APPARATUS

The present invention provides a process for recovering liquid chemical products, in which the residual liquid chemical products remaining in respective handling devices in a chemical production facility can be efficiently and safely recovered therefrom without leakage thereof out of the system. In the process for recovering liquid chemical products in a chemical production facility according to the present invention, the chemical products are withdrawn from the handling devices through bottom discharge pipes (14), (15), (16) and (17) thereof, directly collected by the gravity thereof into a common inclined collection pipe (13) located at a position lower than the bottom discharge pipes and connected to the bottom discharge pipes, and then delivered by the gravity thereof through the inclined collection pipe (13) to a recovery tank (1) located at a position lower than the inclined collection pipe and connected to a lower end of the inclined collection pipe.
