Abstract: A process for preparing an olefin stream for oligomerization comprises fractionating an olefin stream to provide a light gas stream and a olefin rich stream. Oxygenates are absorbed from the olefin rich stream into a water wash stream to provide an oxygenate rich water wash stream and a washed olefin stream. Oxygenates are then adsorbed from the washed olefin rich stream, so the deoxygenated stream can then be oligomerized.

Abstract: A process for removing butenes from C4-hydrocarbon streams containing butanes and butenes involves extractive distillation with a suitable solvent. The process also involves heat integration, which allows utilization of the heat of the solvent for heating and/or at least partly evaporating various streams.

Abstract: A process is presented for the production of butadienes. The process includes the separation of oxygenates from the product stream from an oxidative dehydrogenation reactor. The process includes quenching the product stream and solvent and oxygenates from the product stream. The oxygenates are stripped from the solvent with an inert gas to reduce the energy consumption of the process, and the solvent is recycled and reused in the process.

Abstract: The invention generally relates to processes for reducing fouling in amine systems and to equipment useful in such processes. Such amine systems are useful for removing one or more acidic gases such as CO2 or H2S from olefin containing hydrocarbon streams. The invention generally relates to minimizing residence time of foulant and foulant precursors at the relatively high temperature found in the amine regenerator and/or to purging the foulant and foulant precursors from the regenerator system. This is accomplished by operating the regenerator column as a stripper (no reflux) and re-routing reflux liquid containing foulant or foulant precursors to a processing location that is less prone to fouling or, optionally, by replacing the reflux liquid with fresh make-up amine or water.

Abstract: A method of making light olefins is described. The method involves producing an alkyne in a pyrolysis process. The alkyne is catalytically hydrogenated in a hydrogenation zone to produce a product stream containing a light olefin. A byproduct stream from the pyrolysis process comprises carbon oxide and hydrogen. The byproduct stream is treated to convert the carbon oxide and the hydrogen to an oxygenated product in a carbon oxide conversion zone, which can then be converted to an olefin in an oxygenate to olefin process.

Abstract: The invention describes a method for separating hydrocarbons in an installation for generating hydrocarbons from a hydrocarbon-containing charge by cleavage. The product gas of the cleavage, which contains gaseous hydrocarbons, is compressed, dried, and supplied as charge material into a separation stage (a front end C3/C4 separation). The front end C3/C4 separation comprises a C4 absorber and a depropanizer. A hydrocarbon fraction consisting of hydrocarbons having a maximum of 3 carbon atoms is obtained as a gaseous overhead product of the C4 absorber. A liquid hydrocarbon fraction consisting of hydrocarbons having at least 4 carbon atoms is obtained as a bottom product of the depropanizer. The front end C3/C4 separation comprises an additional process technological C2/C4 separation stage is arranged between the C4 absorber and the depropanizer.

Abstract: A method for removal of an organic amine from a hydrocarbon stream includes mixing the hydrocarbon stream including the amine with an aqueous inorganic acid in a volumetric ratio of hydrocarbon stream: aqueous inorganic acid of greater than 1.5:1 to 5:1, phase separating a hydrocarbon phase and an aqueous phase, removing the hydrocarbon phase, mixing the aqueous phase with an aqueous alkaline solution, phase separating the aqueous phase and an organic phase, and removing the organic phase. The aqueous inorganic acid has a concentration of greater than or equal to 30 weight percent. The disclosed method results in improved phase separation time during an amine removal process.
