Abstract
A test apparatus for qualifying compositions used to reduce scale deposition in fluid, e.g., wax deposition in crude oil, is disclosed. The test apparatus includes a first reservoir capable of holding a first fluid, and a second rotatable reservoir disposed within the first reservoir, the second reservoir capable of holding a second fluid. The apparatus includes a fluid inlet through which the second fluid enters the second reservoir, and a fluid outlet through which the second fluid exits the second reservoir, wherein a bottom surface of the second rotatable reservoir is configured to be at least partially submerged in the first fluid so that precipitate from the first fluid can be deposited thereon.
