Abstract: A hand-held multi-dose dispensing apparatus (10) comprising a metering chamber (20) having an axis (21), an end portion (22) at one axial end of the chamber (20) and a side body portion (23) extending from the axial end portion (22), a piston arrangement (30) movable with a piston stroke along the axis of the metering chamber (20) with a seal portion (34) of the piston arrangement (30) being slidably engageable with an inside surface of a side portion (23) of the metering chamber, an inlet (27) for fluid to enter the metering chamber (20), and an outlet (31, 32) for fluid to be dispensed from the metering chamber (20), wherein the inlet (27) is provided on the side body portion (23) of the metering chamber and, in use, during a first portion of the piston stroke, the inlet (27) is in fluid communication with the metering chamber (20) and during a second portion of the piston stroke, the seal portion (34) of the piston arrangement (30) blocks the inlet (27) preventing fluid from passing from the inlet (27) into the metering chamber (20). This dispensing apparatus (10) reduces variations in the shot weight dispensed, by the metering of the fluid commencing at the point at which the piston enters the second portion of its stroke blocking off the inlet.

Abstract: A feed stream, comprising hydrogen sulphide (H2S), carbon dioxide (CO2), hydrogen (H2) and, optionally, carbon monoxide (CO), is separated into at least a CO2 product stream and an H2 or H2 and CO product stream. The stream is separated using a pressure swing adsorption system, an H2S removal system and a further separation system, which systems are used in series to separate the stream. The method has particular application in the separation of a sour (i.e. sulphur containing) syngas, as for example produced from the gasification of solid or heavy liquid carbonaceous feedstock.

Abstract: A feed gas comprising CO2, H2S and H2 is treated to produce an H2-enriched product and an H2S-lean, CO2 product. The feed gas is separated to provide the H2-enriched product and a stream of sour gas. The stream of sour gas is divided into two parts, one of which is processed in an H2S removal system to form one or more streams of sweetened gas, and the other of which bypasses the H2S removal system, the stream(s) of sweetened gas and the sour gas bypassing the H2S removal system then being recombined to form the H2S-lean, CO2 product gas. The division of the sour gas between being sent to and bypassing the H2S removal system is adjusted responsive to changes in the H2S content of the sour gas, so as to dampen or cancel the effects of said changes on the H2S content of the H2S-lean, CO2 product gas.

Abstract: Carbon monoxide (CO) may be removed from flue gas generated by oxyfuel combustion of a hydrocarbon or carbonaceous fuel, by contacting the flue gas, or a CO-containing gas derived therefrom, at a first elevated temperature, e.g. at least 80° C., and at a first elevated pressure, e.g. at least 2 bar (0.2 MPa), with at least one catalyst bed comprising a CO-oxidation catalyst in the presence of oxygen (O2) to convert CO to carbon dioxide and produce carbon dioxide-enriched gas. The carbon dioxide produced from the CO may be recovered from the carbon dioxide-enriched gas using conventional carbon dioxide recovery techniques. NO in the flue gas may also be oxidized to nitrogen dioxide (NO2) and removed using conventional NO2 removal techniques, or may be reduced in the presence of a reducing gas to nitrogen (N2) which does not have to be removed from the gas.

Abstract: NO2 may be removed from a carbon dioxide feed gas comprising NOx and at least one “non-condensable” gas as contaminants by passing the feed gas at a first elevated pressure through a first adsorption system that selectively adsorbs at least NO2 to produce at least substantially NO2-free carbon dioxide gas. The adsorption system is at least partially regenerated using a carbon dioxide-rich gas recovered from the substantially NO2-free carbon dioxide gas after purification. The invention has particular application in removing NOx and water from flue gas generated by oxyfuel combustion.

Abstract: An improved control scheme is set forth for an adsorption process that removes water and carbon dioxide (CO2) from a feed gas using a hybrid of both temperature swing (i.e. TSA) and pressure swing (PSA) to regenerate the adsorbent. The control scheme comprises adjusting the quantity of heat to be provided by the regeneration gas as a function of temperature data taken within a strategic portion of the water selective adsorbent zone. The strategic portion corresponds to the location for the desired transition from regeneration by temperature swing, to regeneration by pressure swing. In a preferred embodiment of the present invention, said quantity of regeneration heat is also adjusted as a function of the water content of the feed gas.
