Patent number: 10940427Abstract: Disclosed is a process for the regeneration of an adsorber. For the regeneration a liquid stream (S2) is applied which is obtained by hydrogenation of a stream (S1) comprising at least one alkane and least one olefin. The stream (S2) comprises one alkane and a reduced amount of at least one olefin compared to the amount in the stream (S1). Then the stream (S2) is converted from the liquid into the gaseous phase and the adsorber is regenerated by contact with the gaseous stream (S2).Type: GrantFiled: October 9, 2014Date of Patent: March 9, 2021Inventors: Hans-Guenter Wagner, Christoph Bayer, Lothar Karrer, Heinz Ruetter, Patrik Pietz, Sven Crone, Markus Eggersmann, Kam Wing Wong

Patent number: 10894921Abstract: Disclosed is a process for the regeneration of an adsorber (A1). The adsorber (A1) is regenerated by contact with a gaseous stream (S2) and the outflow of the adsorber (A1) comprising condensate of stream (S2) and organic composition (OC1) collected in a device. After regeneration of the adsorber (A1) the stream (S2) in the adsorber (A1) is replaced completely or at least partially by the content of the device. Then the adsorber (A1) is fed with organic composition comprising at least one olefin, at least one alkane and at least one compound containing oxygen and/or sulfur.Type: GrantFiled: October 9, 2014Date of Patent: January 19, 2021Assignee: BASF SEInventors: Hans-Guenter Wagner, Christoph Bayer, Lothar Karrer, Sven Crone, Markus Eggersmann, Kam Wing Wong, Patrik Pietz, Heinz Ruetter

Patent number: 10807018Abstract: Disclosed is a process for the purification of an organic composition (OC1) by adsorption using an assembly containing at least two adsorbers. The organic composition (OC1) comprising at least one alkane, at least one olefin and at least one compound containing oxygen and/or sulphur is fed into a first adsorber (A1) of the assembly in order to obtain an organic composition (OC2) comprising at least one alkane, at least one olefin and a reduced amount of at least one compound containing oxygen and/or sulphur compared to the respective amount in organic composition (OC1). Hydrogenation of the organic composition (OC2) provides a stream (S2) comprising at least one alkane and a reduced amount of at least one olefin compared to the respective amount in organic composition (OC2) obtained after feeding into the first adsorber (A1). A second adsorber (A2) of the assembly is regenerated by contact with stream (S2).Type: GrantFiled: October 9, 2014Date of Patent: October 20, 2020Assignee: BASF SEInventors: Hans-Guenter Wagner, Christoph Bayer, Lothar Karrer, Markus Eggersmann, Sven Crone, Kam Wing Wong, Heinz Ruetter, Patrik Pietz

Patent number: 10137400Abstract: The invention relates to a process for the regeneration of an adsorber. For the regeneration a liquid stream (S2) comprising at least one alkane is converted from liquid phase into gaseous phase. Then the adsorber is regenerated and heated by contact with gaseous stream (S2) up to 230 to 270° C. Subsequently, the adsorber is cooled first by contact with gaseous stream (S2) to a temperature of 90 to 150° C. followed by cooling with liquid stream (S2) to a temperature below 80° C. The outflow of the adsorber (S2*) during the cooling with gaseous stream (S2) and optionally the outflow of the adsorber (S2*) during cooling with liquid stream (S2) is recycled in at least one of these steps.Type: GrantFiled: October 9, 2014Date of Patent: November 27, 2018Assignee: BASF SEInventors: Hans-Guenter Wagner, Christoph Bayer, Lothar Karrer, Heinz Ruetter, Patrik Pietz, Sven Crone, Markus Eggersmann, Kam Wing Wong
