    Abstract: A method of operating a dump tank of a polymer production process by transferring all or a portion of a content of a polymerization reactor into the dump tank, wherein the reactor contents comprise solid polymer, and liquid and gaseous non-product components, and removing at least a portion of the liquid and gaseous non-product components from the dump tank by: reducing a pressure of the dump tank, subjecting the solid polymer to a first cleaning stage comprising heating the solid polymer by introducing a first heated treatment gas into the dump tank, and subjecting the solid polymer to a second cleaning stage comprising purging the solid polymer by introducing a second heated treatment gas into the dump tank.

    Abstract: A distributor element comprising: at least three plates, each plate comprising openings, each of the levels between adjacent plates having walls extending from one side of one plate onto an adjacent side of an adjacent plate to define a channel, the channels fluid-tightly connecting all of the openings between adjacent plates, in each of the levels between the walls, one or more hollow spaces being formed, each of the plates comprising at least one aperture not being fluid-tightly connected with the openings of an adjacent plate by a channel, in each level between the at least one aperture of the adjacent plate at least two fluid paths extend in the one or more hollow spaces, all of the at least two fluid paths of each level having a substantially same length, and a number of fluid paths increasing at least for 75% of the plates from level to level.
