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.
本发明公开了包括高达 20 wt % 的石蜡抑制聚合物和非聚合酯化合物的组合物,其中组合物在约 0° C 至 -40° C 或约 -20° C 至 -40° C 的温度下流动、在现场条件下进行石油开采、提炼、储存和运输时,这些组合物可用于抑制石蜡沉积,其中的浓缩物可泵送和浇注,不会沉淀,在低至零下 40 摄氏度和高至 60 摄氏度的温度下,在封闭容器内也不会出现高压积聚。
