20120285195 | SEPARATION OF GASES - A method of separating a carbon-dioxide-rich liquid stream from a synthesis gas including carbon dioxide and hydrogen, includes carrying out a first cooling step to cool a synthesis gas feed stream using at least one heat exchanger such that a first two-phase mixture is formed. The first two-phase mixture is passed at a first pressure and a first temperature to a first separator and a first separation is carried out to separate the first mixture into a first CCVrich liquid stream and a H2-Hcli gas stream. The H2-rich gas stream is pressurised and a second cooling step is carried out to cool the H2-rich gas stream using at least one heat exchanger such that a second two-phase mixture is formed. The second mixture is passed at a second pressure and a second temperature to a second separator, the second pressure being higher than the first pressure and a second separation is carried out to separate the second mixture into a second CO2-rich liquid stream and a further H2-rich gas stream. Preferred examples further include the step of expanding at least one of the separated H2-rich vapour streams to recover mechanical work and/or to cool the H2-rich stream and subsequently using the expanded H2-rich stream as a coolant in the separation system. | 11-15-2012 |

20100206384 | APPARATUS FOR CHECKING MECHANICAL COMPONENT PARTS WITH OPTICAL DEVICES, AND RELEVANT PROTECTION DEVICE AND METHOD - An apparatus for checking mechanical component parts, such as tools in machine tools, uses optical devices for emitting and receiving a light beam, for example a laser beam, and sensors for detecting the interruption of such light beam. A protection device for at least one of the optical devices includes pneumatic conduits and a nozzle outputting an air stream from a plurality of holes located around the central conduit through which the light beam passes, so generating a tubular shield which embraces the light beam. The protection device further includes a shutter which can be displaced from a rest position, wherein the central conduit is closed and the inside of the protection device is pressurized, to a working position, wherein the nozzle delivers the air stream in the form of a tubular shield. Passing from the rest position to the working position, the shutter assumes an intermediate transit position in which an air blast is outputted through the central conduit for a short time interval. The shutter has cylindrical surfaces and slides inside a shell of the protection device, driven by plane antirotation surfaces, too. | 08-19-2010 |
