Claim Text:
1. A fluid comprising a water-in-oil emulsion having an electrical stability of greater than 1000V when determined according to API 13B-2, and comprising an aqueous phase and a reclaimed oil recovered by direct thermal desorption from a peptized substrate comprising a mixture of oil and water and a solid, acid-treated sorbent material, the reclaimed oil comprising: (a) a non-zero total BTEX concentration of less than 1 wt %, determined according to ASTM D-5790 or US EPA 8260; (b) an aniline point of greater than or equal to about 69° C. as determined by ASTM-D611; (c) a kinematic viscosity of equal to or greater than 2 cSt at 40° C. as determined according to ASTM-D445 or ASTM-D88; (d) a non-zero sulfur content; (e) a flash point of greater than or equal to about 100° C., as determined using the Pensky-Martens closed cup analysis according to ASTM D93; (f) a pour point of less than or equal to −15° C., as determined according to ASTM D-92; (g) a specific gravity of 0.82 or greater as determined according to ASTM-D1298 or ASTM-D287; and (h) a non-zero nitrogen content.
