Abstract: 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.

Abstract: An absorbent article is disclosed. The article includes a first portion having at least two target strips located on opposite ends of the first portion, at least one visual sizing indicator positioned on the first portion of the article between the at least two target strips, the visual sizing indicator including indicia for indicating that the article is too large for a wearer, a middle portion contoured inwards such that an hourglass shape is formed, and a second portion having at least two fasteners located on opposite edges of the second portion. The absorbent article is formed of several layers including a moisture-impervious outer layer, an inner layer substantially co-extensive with the outer layer, and a filler interposed between the inner layer and the outer layer.
