Separations System for Recovering Hydrocarbons from Synthesis of Polyethylene Polymers
The present disclosure provides for a separations system for separating ethylene, 2-methylbutane and at least one unsubstituted (C6-C12) hydrocarbon in a multi-component condensate mixture. The separations system includes a feed conduit in fluid communication with a source of the multi-component condensate mixture, a stripper column in fluid communication with the feed conduit, where the stripper column separates the multi-component condensate mixture into a heavies component mixture with at least one unsubstituted (C6-C12) hydrocarbon, and a top mixture having a medium component (s) that include at least the 2-methylbutane and a light component (s) that include at least the ethylene. The separations system further includes a flash drum that separates the top mixture into the medium component (s) and the light component (s). The separations system does not include a distillation column disposed between the source of the multi-component condensate mixture and the flash drum.
Integrated perchloroethylene decomposition reactor design for C4 and C5-6 isomerization units
Processes incorporating a common organic chloride decomposition reactor and chloride treater to be used by both the C.sub.4 and C.sub.5-6 isomerization reaction zones are described. A portion of the C.sub.4 isomerization reaction zone off gas is routed to the C.sub.4 HCl absorber, which provides about 85% of the HCl requirement for the C.sub.4 isomerization reaction zone. A small amount of the C.sub.5-6 isomerization reaction zone off gas is mixed with the C.sub.4 isomerization reaction zone off gas portion going to the C.sub.4 HCl absorber.

Isomerization and catalytic activation of pentane-enriched hydrocarbon mixtures
The present disclosure relates to processes that catalytically convert a hydrocarbon feed stream predominantly comprising both isopentane and n-pentane to yield upgraded hydrocarbon products that are suitable for use either as a blend component of liquid transportation fuels or as an intermediate in the production of other value-added chemicals. The hydrocarbon feed stream is isomerized in a first reaction zone to convert at least a portion of the n-pentane to isopentane, followed by catalytic-activation of the isomerization effluent in a second reaction zone with an activation catalyst to produce an activation effluent. The process increases the conversion of the hydrocarbon feed stream to olefins and aromatics, while minimizing the production of C1-C4 light paraffins. Certain embodiments provide for further upgrading of at least a portion of the activation effluent by either oligomerization or alkylation.
