Abstract
Compositions and methods for cleaning a surface are generally provided. In some embodiments, a fluid comprising a solvent and a second component is provided. In some cases, the solvent is a terpene. The fluid generally has a flash point of at least about 140 ° F. In some cases, second component comprises an unsaturated alkyl ester at least 10 carbons in length. In certain embodiments, the method comprises contacting a surface with the fluid to remove heavy oil and/or asphaltenes from the surface.
Claims29
A fluid comprising:
- a terpene;
- and
- a second component comprising a structure as in Formula (I):
- wherein each Q1 and Q2 are the same or different and are selected from the group consisting of optionally substituted alkylenes, optionally substituted alkenylenes, optionally substituted alkynylenes, optionally substituted heteroalkylenes, optionally substituted arylenes, and optionally substituted heteroarylenes, wherein the second component has a degree of unsaturation between 0-17;
- wherein m is 4-33, n is 1-10, and m+n is 9-34;
- wherein the fluid comprises X wt % of the second component versus the total fluid weight, wherein X is between about 50 and about 99;
- wherein the fluid comprises (100-X) wt % of the terpene versus the total fluid weight;
- and
- wherein the fluid has a flash point of at least about 140° F.
