摘要:
A first contaminant selected from oxygen and carbon monoxide is removed from impure liquid carbon dioxide using a mass transfer separation column system which is reboiled by indirect heat exchange against crude carbon dioxide fluid, the impure liquid carbon dioxide having a greater concentration of carbon dioxide than the crude carbon dioxide fluid. The invention has particular application in the recovery of carbon dioxide from flue gas generated in an oxyfuel combustion process or waste gas from a hydrogen PSA process. Advantages include reducing the level of the first contaminant to not more than 1000 ppm.
摘要:
A fluid-filled structure, such as a bladder, is disclosed. The bladder has a first surface and an opposite second surface that are peripherally joined to define various edges. The bladder encloses a fluid between the first surface and the second surface. A portion of the edges may have a concave configuration, or the edges may have both concave and convex configurations. A shape of the bladder may be a tessellation pattern so that a plurality of the bladder may be efficiently.
摘要:
A method of controlling engine operation in a vehicle in response to a misfire of one of a plurality of engine cylinders fueled through fuel injectors. The vehicle includes a fuel vapor storage canister. The method includes disabling at least one of the fuel injectors, using an open loop to control fuel delivery by the injectors to the cylinders, and disabling purging of the canister. The disabling and using steps are performed while the misfire continues.
