Abstract: In the high pressure polymerization of ethylene homopolymers or copolymers, conditions in the high pressure recycle system may lead to the build-up of low molecular weight oligomers and waxes. Sequentially draining knock-out pots, located downstream of a high pressure separator, at regular intervals can reduce the build-up of low molecular weight oligomers and waxes during the high pressure polymerization of alpha olefins.

Abstract: In accordance with the present invention, there is provided a food container assembly that includes a plurality of pre-packaged rigid containers, each containing an amount of food, that are vertically stacked within a tubular receptacle having oxygen (and optionally moisture) barrier properties. Each container (1) includes: (i) a bowl (11) having a closed bottom (14), an inner surface (17) defining a bowl interior (20), and an upper rim (23) defining an open top (26); (ii) a sleeve (29) having an outer surface (32) and a lower edge (35), and extending downwardly from upper rim (23) of bowl (11); (iii) an amount of food (44) residing within bowl interior (20); and (iv) a removable polymer film (47) sealingly engaging upper rim (23) of bowl (11), thereby sealing open top (26) of bowl (11) and containing food (44) within bowl interior (20). The plurality of containers (1) are arranged in a vertical stack (e.g., 2 or 3) having an outer edge (53).
