Storage tank for viscous oil containing easily polymerizable compounds

Abstract

This invention relates to a storage tank for a viscous oil containing easily polymerizable compounds. A storage tank of the present invention for strong viscous oil containing easily polymerizable compounds, comprising a bottom plate 12, a side wall 13, a draw-off pipe 3 and a inlet pipe 2. The bottom plate 12 slopes downward toward the draw-off pipe 3 and an angle of downward inclination of the bottom plate 12 is gradient at least 1/200. It becomes possible by the present inventive storage tank to effectively prevent the polymerization of the easily polymerizable compounds contained in the waste oil within the storage tank and the clogging of a pipe is suppressed considerably.
