    Abstract: A containment for crude oil that inhibits paraffin deposition thereon is described. One to twenty coatings of a composition including a polyacrylate are applied to a crude oil contact surface of a crude oil containment; the polyacrylate includes at least about 50 mole % acrylic acid residues or the conjugate base thereof. The coating compositions are suitably delivered from a water dispersion, solution, or emulsion and dried before applying a subsequent coating. Each of the one to twenty coatings are formed from the same or from different polyacrylate coating compositions. The coated containment surfaces inhibit deposition of at least 10 wt % and as much as 90 wt % of paraffin solids from a crude oil compared to the same crude oil contact in the absence of the one to twenty coatings. The coatings inhibit paraffin deposition at temperatures between about 60° C. and −40° C.

    Abstract: Disclosed are compositions including up to 20 wt % of a paraffin inhibiting polymer and one or more non-polymeric glycol ether compounds, wherein the compositions are stable and flow at a temperature between about 0° C. and −40° C., in many cases between about −20 C. and −40° C. The glycol ether compounds are non-polymeric, are liquids at 20° C. (1 atm) and have boiling points over 100° C., in many cases over 200° C. The compositions are useful paraffin inhibitor concentrates for use in the petroleum industry wherein the concentrates are stable, pumpable, and pourable at temperatures as low as −40° C. and as high as 60° C.
