Patent ID: 8382959

Claim:
A transportable hydrocarbon-recovery unit formed of an evaporation system and a condensation system, the evaporation system comprising: means for supplying a material; means for conveying the material; an inclined rotary cylinder isolated in a cylindrical structure; means for rotating the rotary cylinder within the cylindrical structure; means for heating the rotary cylinder; and means for removing an excess of the material, wherein said evaporation system is arranged over a trailer structure so that it can be moved; the means of supplying material including means of controlling a supply of the material; and said inclined rotary cylinder including internal treatment-chamber means, which includes: a plurality of internal cleaning means, arranged and distributed at equal distances along a length of the rotary cylinder; means for increasing a heat-transfer area of the material, which open and close once for each revolution of the rotary cylinder, to accumulate material and increase the heat-transfer area; and wherein the means for removing excess material includes a body that is substantially cylindrical inside and out and with a discharge chute, and which includes means for increasing hermeticity, with a rotary doorway with associated means for opening and closing same, which opens once for each revolution.
