    Abstract: Disclosed herein are graphene quantum dot tagged paraffin suppressants such as graphene tagged paraffin inhibitors and paraffin dispersants and methods of making and using thereof. The graphene quantum dots are covalently bound to residues of paraffin inhibitors or dispersed with paraffin dispersants to form tagged paraffin suppressants active in inhibiting paraffin crystallization or dispersing crystalized paraffin wax in crude oils and compositions comprising crude oils. The dots can be tailored to fluoresce at wavelengths with minimized correspondence to the natural fluorescence of crude oils, enabling the measurement of the concentration of the paraffin suppressants in crude oils or compositions comprising crude oils. The tagged suppressants are used to trace the dispersion and disposition of the paraffin suppressants in oils and compositions comprising them, for example within crude-oil recovery, production, processing, or conveyance and transportation, by in situ sampling the oil or composition and measuring the fluorescence of the sampled material.

    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.

    IPC: C09K8/524

    Abstract: Disclosed are compositions including up to 20 wt % of a paraffin inhibiting polymer and a non-polymeric ester compound, wherein the compositions flow at a temperature between about 0° C. and −40° C., or between about −20° C. and −40° C. The non-polymeric ester compounds are liquids at 20° C. and atmospheric pressure, and have boiling points over 100° C., in many cases over 200° C. The compositions are useful to inhibit paraffin deposition during petroleum recovery, refining, storing, and transporting under field conditions, wherein the concentrates are pumpable and pourable, do not precipitate, and do not exhibit high pressure buildup inside enclosed containers at temperatures as low as −40° C. and as high as 60° C.

    Abstract: Disclosed are compositions including up to 20 wt % of a paraffin inhibiting polymer, a refined petroleum distillate and one or more low Log P molecules, 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 low Log P molecules are non-polymeric, have a Log P of less than 1, are liquids at 20° C. (1 atm), and have boiling points over 60° C., in many cases over 100° 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.
