Solvent compositions for removing petroleum residue from a substrate and methods of use thereof |
摘要 |
Water-soluble solvent compositions, including from about 10% to about 60% by weight of an aromatic ester; from about 30% to about 60% by weight of an aliphatic ester; from 0% to about 15% by weight of a co-solvent; from 0% to about 20% of one of a cyclic terpene and a terpenoid; from 0% to about 1% by weight of an odor-masking agent; and from 0% to about 20% by weight of a nonionic surfactant, for removing petroleum residue from a substrate, and methods of use thereof. The composition can further comprise water. The composition also can comprise an aqueous solution. The method for removing petroleum residue from a substrate can further comprise recycling the solvent composition by using a countercurrent separation column charged with compressed ammonia and/or carbon dioxide and a spinning band distillation column to separate the solvent composition from the petroleum residue.
