  • Publication number: 20150152363
    Abstract: 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.

  • Patent number: 8507421
    Abstract: A process includes adding an effective amount of a calcium lignin sulfonate to a thickened base grease to form a lubricating grease wherein the calcium lignin sulfonate has a molecular weight of at least 10,000 g/mol; the calcium lignin sulfonate has a water content of less than about 0.5 wt %; the effective amount is from about 1 wt % to about 20 wt % based upon the weight of the lubricating grease; the thickened base grease is obtained from a grease forming process or a lubricating paste; and the lubricating grease has a water solubility below about 3 wt %, as determined by a water wash out-test.
