  • Patent number: 9169404
    Abstract: The present invention relates to a specific aqueous separation liquid and to a process for removing paint overspray from a paint spray booth comprising: i) directing a gas stream through a paint spray booth; ii) contacting paint overspray with the gas stream flowing through the paint booth thereby forming a paint loaded gas stream containing paint particles or droplets dispersed therein, iii) forming a flowing substantially continuous liquid film of the aqueous separation liquid on a surface positioned within the flow path of the gas stream; iv) directing the paint loaded gas stream to said surface, in order to bring the gas stream in contact with the flowing substantially continuous film of the aqueous separation liquid, thereby transferring paint particles or droplets from the gas stream into the separation liquid to form a first paint loaded separation liquid; and v) removing the first paint loaded separation liquid and the gas stream having a reduced paint load.
