Abstract: A process for the separation of an aldehyde and a second component from a feed stream (3a, 3b, 3c) comprising the aldehyde and the second component, said process comprising: providing the feed stream to one or both of a first separation vessel (1) operating at a first pressure and a second separation vessel (2) operating at a second pressure wherein said second pressure (2) is greater than said first pressure; operating said first separation vessel (1) and said second separation vessel (2) such that separation occurs; recovering an aldehyde product stream (4) from at or near the bottom of the first separation vessel (1), said aldehyde product stream (4) having a concentration of aldehyde which is higher than that in the feed stream (3a, 3b, 3c); recovering a second component stream (8) from at or near the top of the second separation vessel (2), said second component stream having a concentration of second component which is higher than in the feed stream (3a, 3b, 3c); removing a first recycle stream (5, 6) f

Abstract: The present invention relate to processes for converting olefins to alcohols, ethers, or combinations thereof that are suitable for use as a gasoline additive. In one embodiment, the process comprises (a) receiving a feed stream, wherein the feed stream comprises one or more olefins having 2 to 5 carbon atoms in an amount of up to 80% by weight based on the weight of the feed stream; (b) hydroformylating the feed stream in the presence of a catalyst to convert at least 80% of the olefins from the feed stream to oxygenates; (c) separating a product stream from step (b) into an oxygenate stream and a stream comprising unreacted olefins, inerts, the catalyst, and the remaining oxygenates; and (d) treating the oxygenate stream to convert a plurality of the oxygenates into at least one of an alcohol, an ether, or combinations thereof is suitable for use as a gasoline additive.

Abstract: A process for the distillation of an aldehyde mixture comprising a straight-chain aldehyde and a branched-chain aldehyde is described in which the process comprises: supplying a feed comprising the aldehyde mixture to a first separation vessel; operating said first separation vessel at a first temperature and a first pressure such that separation occurs; recovering a first stream comprising the straight-chain aldehyde from said first separation vessel and supplying said first stream to a second separation vessel; operating said second separation vessel at a second temperature and a second pressure such that separation occurs; recovering a product stream comprising the straight-chain aldehyde and a second stream comprising high-boiling components from said second separation vessel, and supplying said second stream to a third separation vessel; operating said third separation vessel at a third temperature and a third pressure such that separation occurs; and recovering a third stream comprising the aldehyde mix

Abstract: A process for the production of one or more product fuels, particularly product motor fuels comprising: recovering a stream comprising olefin from one or more processing units within an oil refinery; feeding said olefin stream to a hydroformylation zone within the refinery; contacting said olefin stream with carbon monoxide and hydrogen in the presence of a hydroformylation catalyst and operating said hydroformylation zone under hydroformylation conditions such that at least a portion of the olefin is converted to an aldehyde having an additional carbon atom to the olefin; recovering a stream comprising said aldehyde from the hydroformylation zone and passing said aldehyde stream to a hydrogenation zone operated under hydrogenation conditions such that at least a portion of the aldehyde is converted to the corresponding alcohol; and recovering a stream comprising alcohol and forwarding the alcohol to one or more product fuel pools, preferably product motor fuel pools within the refinery.

Abstract: A process for production of dialkyl succinate from bio-succinic acid feedstock where solid bio-succinic acid is fed to a reactor to react with alkanol by autocatalytic esterification. Products from the reactor including unreacted succinic acid, mono alkyl ester, dialkyl ester, alkanol, water and impurities are sent to a reaction distillation column for esterification of succinic acid and further esterification of mono alkyl ester with upflowing alkanol. The bottoms products from the reaction distillation column including residual succinic acid, mono alkyl ester, dialkyl ester, impurities and alkanol are sent to a bottoms stream separation zone where di-alkyl ester is separated from alkanol, succinic acid, mono alkyl ester and impurities. The tops products from the reaction distillation column including alkanol, water and organic components are sent to a top stream distillation zone where alkanol is separated from water and organic components. The organic components are recycled to the reaction zone column.

Abstract: A process for the production of dialkyl succinate from a bio-succinic acid feedstock commencing by feeding bio-succinic acid to a reaction distillation column to enable esterification of the succinic acid. The feedstock is passed co-currently with upflowing alkanol such that an esterification reaction occurs. An overhead vapor stream is removed from the reaction distillation column comprising di-ester, alkanol, water of esterification and organic components. The vapor stream is sent to an alkanol separation column where alkanol is separated from the water of esterification and organic components. A side draw is removed from the alkanol separation column comprising partially immiscible organic and aqueous phases. The side draw is passed to a phase separation apparatus where the partially immiscible organic and aqueous phases are separated. The organic phase is passed to a column where the dialkyl succinate is recovered from residual water and other organic components.
