A rotary feeder having a stationary, cylindrical housing having disposed therein a number of injection nozzles, and within which rotate a plurality of vanes about a central axis, wherein pairs of adjacent vanes of the plurality of vanes define wedge volumes, wherein the housing extends a width along the central axis, wherein each of the vanes has a length along the central axis, and wherein the injection nozzles are positioned across the width of the housing, such that a spray pattern of a gas injected via the number of injection nozzles spans substantially the entire length of the vanes.

Rotary feeder with cleaning nozzles

A rotary feeder comprising a stationary, cylindrical housing having disposed therein a number of injection nozzles, and within which rotate a plurality of vanes about a central axis, wherein the housing extends a width along the central axis, wherein each of the vanes has a length along the central axis, and wherein the injection nozzles are positioned across the width of the housing, such that a spray pattern of a gas injected via the number of injection nozzles spans substantially the entire length of the vanes. A system comprising and a method utilizing such a rotary feeder are also provided herein.

A fractionation system for a polymerization reactor includes a membrane separation system designed to separate light components, such as unreacted monomer and inerts, from diluent. The membrane separation system may employ one or more membrane modules designed to separate hydrocarbons based on size, solubility, or combinations thereof. The fractionation system also may include a heavies fractionation column designed to separate heavy components, such as unreacted comonomer and oligomers, from the diluent.
