Abstract: An ethylene recycle method may include: obtaining an overheads stream comprising ethylene in a first gaseous state from an ethylene purification column; heating the overheads stream in a first heat exchanger to produce a heated overheads stream comprising the ethylene in a second gaseous state; compressing the heated overheads stream to yield a compressed ethylene stream comprising the ethylene in a first supercritical state; cooling the compressed ethylene stream to produce a cooled, compressed ethylene stream comprising the ethylene in a first liquid state, wherein the cooling comprises passing the compressed ethylene through the first heat exchanger; reducing the pressure of the cooled, compressed ethylene stream to produce a first recycle stream comprising the ethylene in a second liquid state and optionally a third gaseous state; and introducing the first recycle stream into the ethylene purification column.

Abstract: Methods and systems for analyzing the carbon number distribution of distillation fractions may utilize a fast gas chromatograph. For example, methods may comprise: distilling a hydrocarbon feed to provide a plurality of distillation fractions using a distillation column; obtaining a draw stream from one or more of the plurality of distillation fractions; and analyzing the draw stream with a fast gas chromatograph to directly determine a carbon number distribution of the draw stream, the fast gas chromatograph having a cycle time that is less than a residence time of a specified component of the draw stream within the distillation column, and the fast gas chromatograph being in-line with or in parallel with the draw stream.

Abstract: The present invention concerns a process for oligomerizing an olefin feedstock to form an oligomerization product, and a method of controlling such an oligomerization process. The process comprises oligomerizing propylene to form a Cn olefin, including contacting a feed stream comprising propylene and a recycle fraction with a solid phosphoric acid oligomerization catalyst under effective oligomerization conditions in an oligomerization reactor to produce an oligomerization effluent; and fractionating the oligomerization effluent to obtain a product fraction and the recycle fraction, the product fraction comprising the Cn olefin and the recycle fraction comprising a Cn-3 olefin; wherein the recycle fraction comprises at least 80 wt % of the Cn-3 olefin, based on the weight of the recycle fraction; and wherein n is 9, or 12.

Abstract: Linear alpha olefins (LAOS) may be formed by oligomerization of ethylene in the presence of a Ziegler-type catalyst. The presence of trace water during oligomerization can result in unwanted formation of insoluble higher oligomers or polymer. Methods for limiting the presence of water during ethylene oligomerization reactions may include separating residual ethylene and 1-butene from an LAO product stream to form a higher LAO-enriched stream comprising C6+ LAOs, separating 1-hexene as an overhead stream from the higher-LAO enriched stream using a first distillation column, obtaining separated solvent as a side stream from the first distillation column or as a side stream from a first of one or more downstream distillation columns, and returning the separated solvent to a reactor in a recycled solvent stream. The recycled solvent stream passes through one or more driers before returning to the reactor.
