An apparatus and method are provided for use in removal of coatings from airplanes and the like wherein such removal requires the application of a solvent composition for dissolving the coating such as paint, the solvent having a sufficiently high vapor pressure to be present in both a liquid phase and a gaseous vapor phase at stripping temperatures with the solvent in the vapor phase being lighter than the liquid phase and heavier than air, and the apparatus including a portable carriage, positionable beneath the airplane, a receptacle having spaced side walls and carried by the carriage, the side walls extending vertically upwardly, the receptacle further defining a receptacle bottom portion, the receptacle receiving spent solvent in both the liquid and the vapor phases after application of the solvent to the airplane surfaces and dissolution of the paint therein, the side walls directing the received spent solvent in both phases to the receptacle bottom portion such that vapor phase is trapped above the heavier liquid phase by the lighter air thereover, and an exhaust port located above the receptacle bottom portion for removing the vapor phase.

An apparatus for use in the removal of coatings from airplanes, said removal requiring the application of a solvent composition to the surfaces of an airplane for dissolving a coating thereon, said solvent composition having a sufficiently high vapor pressure to be present in both a liquid phase and a gaseous vapor phase at stripping temperatures, said solvent in said vapor phase being lighter than said liquid phase and heavier than air, comprising: a portable carriage positionable beneath said airplane; a receptacle having spaced side walls and carried by said carriage, said side walls extending vertically upwardly, said receptacle further defining a receptacle bottom portion, said receptacle receiving spent solvent in both said liquid and said vapor phases after application of said solvent to said airplane surfaces and dissolution of said paint therein, said side walls directing said received spent solvent in both phases to said receptacle bottom portion such that said vapor phase is trapped above said heavier liquid phase by the lighter air thereover; and an exhaust port located above said receptacle bottom portion for removing said vapor phase. A method for removing paint from airplanes using a solvent for dissolving said paint, said solvent having a sufficiently high vapor pressure to be present in both a liquid and a gaseous vapor phase at stripping temperatures, said solvent in said vapor phase being lighter than said liquid phase and heavier than air, comprising: providing a plurality of portable solvent receiving receptacles; positioning said receptacles beneath said airplane; interconnecting said receptacles at spaced side walls thereof thereby forming a continuous solvent receiving means; stripping said paint from the surfaces of said airplane by applying said solvent thereto; receiving spent solvent in both said liquid and said vapor phases in said continuous solvent receiving means; directing said received spent solvent in both phases to bottom portions defined in said various receptacles such that solvent in said vapor phase is trapped above said heavier liquid phase by the lighter air thereover at said various bottom portions of said interconnected receptacles; and removing said vapor phase from said receptacles through exhaust ports located above said receptacle bottom portions.
