The evaporative emission control canister system has a two-day diurnal breathing loss (DBL) emissions of no more than 20 mg at no more than 210 liters of purge applied after the 40 g/hr butane loading step.
Scrubbing column for cleaning of gas streams
The invention provides a scrubbing column for cleaning gas streams laden with absorbent residues, for example with methanol, and also with solid particles, for example with fuel dust. The gas scrubbing is effected by means of a random packing disposed in the lower region of the scrubbing column and the gas scrubbing of the gas stream laden solely with absorbent residues but not with solid particles by means of a structured packing disposed in the upper region of the scrubbing column. The use of the scrubbing column according to the invention in the integrated plant system between a gasification plant and a plant for gas scrubbing which is operated by the Rectisol process, for example, offers particular advantages with regard to its industrial employability owing to the possible connections described, which bring synergies for efficient operation of the integrated plant system.
Low-pressure drop structure of particle adsorbent bed for adsorption gas separation process
A gas separation unit for the separation of a first gas, carbon dioxide, from a mixture, by using an adsorption/desorption process using a loose particulate sorbent material arranged in at least two stacked layers. The primary heat exchange piping is arranged on the two outer edges of the layer within the cavity extending along a longitudinal direction. Further, an essentially parallel array of secondary heat exchange pipes is provided, the secondary heat exchange pipes extending along a transverse direction. The first diameter of the secondary heat exchange pipes is at least twice as large as the second outer diameter of the secondary heat exchange pipes and the secondary heat exchange pipes are in thermal contact with sheets of metal which extend oscillating between pairwise adjacent secondary heat exchange pipes.
Solvent recovery from sweep gas streams
A method for removing solvent from a solvent containing sweep gas stream obtained from a fertilizer coating process is disclosed. The method can include directly contacting the solvent containing sweep gas stream with an aqueous composition comprising 50% wt/wt to 100% wt/wt of water, condensing at least a portion of the solvent out of the solvent containing sweep gas stream into the aqueous composition to produce a solvent-enriched aqueous composition and a recovered sweep gas stream, and removing the recovered sweep gas stream from the solvent-enriched aqueous composition.
SYSTEM AND METHOD FOR CO2 CAPTURE FROM A FLEET OF CO2 PRODUCING ASSETS
The invention relates to a system and method for CO.sub.2 capture. The system includes a fleet of CO.sub.2 producing assets comprising a fleet of assets having at least two individual assets that produce CO.sub.2 containing gas streams, and a set of modular CO.sub.2 capture units to capture the CO.sub.2 from the CO.sub.2 containing gas streams produced by the fleet of assets, wherein at least one of the individual assets is equipped with not less than two modular CO.sub.2 capture units, and at least one of the modular CO.sub.2 capture units is operated at more than one of the assets during the service life of the modular CO.sub.2 capture unit. The method for CO.sub.2 capture includes providing the fleet of assets and equipping them with a set of modular CO.sub.2 capture units. Advantage over current approaches is performance is optimized across a fleet of assets rather than at an individual site.

METHOD AND DEVICE FOR REDUCING THE INCREASE IN TEMPERATURE AT THE SURFACE OF THE TERRESTRIAL GLOBE, VEHICLE AND STATION FOR IMPLEMENTING SAID METHOD
Disclosed is a method for reducing the increase in temperature at the surface of the earth and the increase in the content of carbon dioxide in the atmosphere due to the fossil fuel and non-fossil fuel combustion operations, remarkable in that it consists in reducing the increase in the temperature of the earth and the increase in the content of carbon dioxide in the atmosphere, which reductions in the temperature of the earth and of the content of carbon dioxide are achieved by reducing the drop in the oxygen content in the atmosphere, which reduction in the drop in the oxygen content includes: producing pure oxygen or producing hydrogen peroxide, and using for fuel combustion the oxygen or hydrogen peroxide to reduce the consumption of oxygen contained in the air during the combustion operations. Also disclosed is the device, the vehicle and the plant for carrying out the method.
