20130259789 | REMOVING SULPHUR OXIDES FROM A FLUID STREAM - A process for removing sulphur oxides from a fluid stream, such as flue gas, that comprises a) providing a non-aqueous absorption liquid containing at least one hydrophobic amine, the non-aqueous absorption liquid being incompletely miscible with water: b) treating the fluid stream in an absorption zone with the non-aqueous absorption liquid to transfer at least part of the sulphur oxides into the non-aqueous absorption liquid and to form a sulphur oxide-hydrophobic amine-complex: c) causing the non-aqueous absorption liquid to be in liquid-liquid contact with an aqueous liquid whereby at least part of the sulphur oxide-hydrophobic amine-complex is hydrolyzed to release the hydrophobic amine and sulphurous hydrolysis products, and at least part of the sulphurous hydrolysis products is transferred into the aqueous liquid; d) separating the aqueous liquid from the non-aqueous absorption liquid. The process mitigates absorbent degradation problems caused by sulphur dioxide and oxygen in flue gas. | 10-03-2013 |
20140065040 | PROCESS FOR SEPARATING OFF ACID GASES FROM A WATER-COMPRISING FLUID STREAM - A process for separating off acid gases from a water-comprising fluid stream wherein the water-comprising fluid stream is contacted in an absorption zone with an absorbent, producing a deacidified fluid stream and an acid gas-loaded absorbent; the deacidified fluid stream is contacted in a scrubbing zone with an aqueous scrubbing liquid, producing a deaminated, deacidified fluid stream and an amine-loaded scrubbing liquid which is cooled, producing an absorber top condensate; the loaded absorbent is passed into a desorption zone producing a regenerated absorbent and desorbed acid gases; the regenerated absorbent is returned to the absorption zone in order to form an absorbent circuit, to which the amine-loaded scrubbing liquid and the absorber top condensate are introduced; and the desorbed acid gases are conducted through an enrichment zone and the acid gases exiting at the top of the enrichment zone are cooled, producing a desorber top condensate. | 03-06-2014 |

20100000834 | Drivetrain with a main drive shaft and drivetrain for a motor vehicle with a drive shaft extending, in particular, out of an engine block - In order to be able to design a connection between a drive side and a transmission side, in particular a damper side, in a drivetrain between a main driveshaft and a torsional vibration damper to be structurally stronger while at the same time having a small installation volume, the invention proposes a drivetrain with a main driveshaft and a torsional vibration damper, wherein the main driveshaft and the torsional vibration damper rotate substantially about a common rotational axis and are connected by means of a connection, wherein the connection can be released in a non-destructible fashion and/or is self-connecting, and wherein a wall is arranged axially between the driveshaft and the torsional vibration damper, which wall is sealed off against the drivetrain by means of a seal, and the drivetrain is characterized in that the connection is arranged radially further remote from the common rotational axis than the seal and than the main driveshaft. | 01-07-2010 |
20110061493 | TRANSMISSION, PARTICULARLY DUAL-CLUTCH TRANSMISSION - The aim of the invention is to be able to make transmissions, in particular dual-clutch transmissions, more stable and compact, especially in respect of a variable moment load. The aim is achieved by a transmission comprising two coaxial transmission input shafts, two countershafts on which gear wheels designed as idlers are rotatably mounted, gear wheels that are arranged in a rotationally fixed and axially successive manner on the two transmission input shafts, are designed as fixed gears, and indirectly or directly mesh with the idlers and thus define different gears, coupling devices which are mounted in a rotationally fixed and axially movable manner on the two countershafts and are to be axially moved by means of adjusting mechanisms in order to connect one respective idler in a rotationally fixed manner to the respective countershaft, and one respective output gear which is mounted on the two countershafts and meshes with teeth of an output member. A reverse gear is defined by an intermediate shaft on which a fixed intermediate shaft gear that immediately meshes with one of the idlers as well as a second fixed intermediate shaft gear that immediately meshes with one of the fixed gears defining the first gear are arranged in a rotationally fixed manner. In the axial sequence of gears, the fixed gear defining the first gear and the reverse gear is arranged on the axially outer side. | 03-17-2011 |
