Use of supercritical Y-grade natural gas liquids for a variety of processes and across numerous industrial applications is described herein. The low viscosity, high density, and tunable solvent properties of supercritical Y-grade natural gas liquids are useful for example in enhanced reservoir recovery and treatment, control of chemical reactions and processes, and/or single or two-phase separations.

A blend of aliphatic hydrocarbons and polyglycol ether(s) is used in a process for cleaning railroad tank cars that have been gravity drained of hydrocarbon fluids but may be left with a residuum containing heavy hydrocarbons, paraffin and noxious gas. A simple recirculation system is established between the chemical source, the contaminated railcar, canister filters and back to the chemical source. Contaminates are removed from the cleaning chemical by the filters and there is no water or steam used which might otherwise damage the railcar.

A composition for treating a hard surface. The composition has: (a) at least one adhesion promoter; (b) at least one surfactant selected from the group consisting of: anionic, non-ionic, cationic, amphoteric, zwitterionic, and combinations thereof; (c) mineral oil; (d) water; (e) optionally, at least one solvent; and wherein the composition is self-adhering upon application to a surface to be treated, and wherein the composition provides a wet film to said surface when water passes over said composition and surface.

A purging agent that has excellent purging performance without generation of aggregate is disclosed as a purging agent used in a purging operation where a resin to be processed contains a polar group-containing thermoplastic resin. This purging agent contain a hydrocarbon-based resin, and at least one metal salt among an alkaline metal salt and alkaline earth metal salt, has a water content of 0.15% by weight or less, and includes 0.1 to 20% by weight of the metal salt expressed as the metal relative to the hydrocarbon-based resin.
