Abstract: A synchronizing device is provided for synchronizing a first rotatable part with a second rotatable part adjacent to the first rotatable part. The synchronizing device includes a first part provided with an engaging sleeve and a second part provided with a synchronizer ring. The synchronizing device has at least one positioning resilient member which is arranged to act upon the synchronizer ring and the second part, in order to allow a design with few parts and also to resynchronize the synchronizing ring with the second part. A transmission including such a synchronizing device is also provided.

Abstract: Recovery of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid using a low energy process. The crude ethanol product is separated in a column to produce a distillate stream comprising acetaldehyde and a residue stream comprising ethanol, acetic acid, ethyl acetate and water. The ethanol product is recovered from the residue stream.

Abstract: Ethanol production from the hydrogenation of acetic acid requires energy to drive the hydrogenation reaction and the purification of the crude ethanol product. Heat integration process to recover heat from one part of the production process to be used within the process improves efficiencies and reduces costs.

Abstract: Recovery of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid. Separation and purification processes of crude ethanol product are employed to allow recovery of ethanol and remove impurities. In addition, the process involves separating the crude ethanol product using an extractive distillation column that employs an extraction agent, such as a recycled stream comprising water.

Abstract: Recovery of alcohol, in particular ethanol, from a crude product obtained from the hydrogenation of a feed stream comprising a carbonylation stock selected from the group consisting of acetic acid, and acetic acid and an ester thereof. The hydrogenation reaction produces a reactor product that is dehydrated to produce a dried product stream that comprises less water than the feed stream. This controls the additional water fed to the hydrogenation unit.

Abstract: A process for producing ethanol comprising the steps of hydrogenating an acetic acid feed stream to form a crude ethanol product and separating at least a portion of the crude ethanol product to form an ethanol stream and at least one vent stream. The vent stream comprises non-condensable gases at least one volatile organic. The process further comprises the step of scrubbing the vent stream with at least two different solvents to recover the volatile organics. The vent stream may also comprise entrained ethanol, which may also be recovered.

Abstract: An improved apparatus and method of producing acetic acid includes condensing overhead vapor to provide reflux to the light ends column as well as condensing vapor from a central portion of the light ends column to increase capacity. Throughput or load on the light ends column is substantially reduced without compromising product quality.
