摘要： A novel method is disclosed for treating a contaminated gas such as a contaminated natural gas or a synthesis product gas from the partial oxidation of petroleum or coal to concentrate and remove hydrogen sulfide at a reduced energy and capital requirement. Hydrogen sulfide in the contaminated stream is absorbed to form a hydrogen sulfide rich solvent which includes co-absorbed carbon dioxide, which is then removed to prevent dilution of the concentrated hydrogen sulfide formed when the solvent is regenerated. The solvent leaving the hydrogen sulfide absorber is heated before entering a high pressure stripper column wherein the co-absorbed carbon dioxide is stripped from the solvent, preferably by stripping with nitrogen or a portion of the product gas, and the carbon dioxide is recycled to the hydrogen sulfide absorber. The CO.sub.2 stripper is operated at a pressure not substantially below the pressure of the hydrogen sulfide absorber, eliminating the need for large compressors required in conventional methods to recycle the carbon dioxide.

摘要： A turbocharged or supercharged internal combustion motive system for utilization of gaseous fuel stored as a liquid wherein the liquefied gaseous fuel is vaporized and warmed at least partially with heat removed from the compressed intake combustion air in the turbocharger or supercharger aftercooler. In a preferred embodiment, the compressed intake combustion air is first cooled in an aftercooler against an ambiently cooled coolant and is subsequently cooled in further aftercooler heat exchange passages against an intermediate coolant which transfers heat removed from the compressed intake combustion air to the liquefied gaseous fuel. Embodiments are disclosed wherein the saturated liquefied gaseous fuel is first subcooled and then pumped to pressures high enough for direct combustion chamber injection and another embodiment discloses vaporization of the saturated liquefied gaseous fuel with compression of the vaporized gas in a compression-type injection system or by low pressure carburetion into the internal combustion engine.

摘要： The present invention relates to an improvement to a process for the removal of acid gases from a feed stream containing acid gases in which the feed gas is cooled and countercurrently contacted with a liquid absorbent in an absorber tower and the spent absorbent is regenerated by distillation wherein dissolved acid gases are stripped from the spent absorbent thereby producing a regenerated liquid absorbent and recycled to the absorber tower.The improvement, which is for the production of a product which is essentially free of sulfur containing compounds and has a reduced concentration of carbon dioxide, comprises the following steps: (a) compressing the acid gas-lean product gas to an elevated pressure and cooling the resultant compressed portion; (b) countercurrently contacting the elevated pressure, cooled, acid gas-lean product gas of step (a) and the regenerated liquid absorbent in a second absorber, thereby producing the product, which is essentially free of sulfur containing compounds and has a reduced concentration of carbon dioxide, at the top of the second absorber and a partially spent absorbent at the bottom of the second absorber, wherein said second absorber is operated at a higher pressure than the operating pressure of said absorber tower; (c) recovering the product, which is sulfur containing compounds and has a reduced concentration of carbon dioxide; and (d) using the partially spent absorbent to contact with the feed gas in the absorber tower.

摘要： An oxygenated organic liquid product and a fuel gas are produced from a portion of synthesis gas comprising hydrogen, carbon monoxide, carbon dioxide, and sulfur-containing compounds in a integrated feed treatment and catalytic reaction system. To prevent catalyst poisoning, the sulfur-containing compounds in the reactor feed are absorbed in a liquid comprising the reactor product, and the resulting sulfur-containing liquid is regenerated by stripping with untreated synthesis gas from the reactor. Stripping offgas is combined with the remaining synthesis gas to provide a fuel gas product. A portion of the regenerated liquid is used as makeup to the absorber and the remainder is withdrawn as a liquid product. The method is particularly useful for integration with a combined cycle coal gasification system utilizing a gas turbine for electric power generation.

摘要： A process is described for the separation of an off-gas from a synthetic fuels production process, such as oil shale retorting, coal gasification, oxygen fireflooding or carbon dioxide miscible flood enhanced oil recovery, into an essentially sulfur-free, light fuel gas and a sulfur containing carbon dioxide gas. The off-gas is contacted with methanol to remove the sulfur containing gases and is then cooled to separate out a light fuel gas from a predominantly carbon dioxide gas. The carbon dioxide gas is again contacted with the same methanol to scrub the latter of sulfur-containing gas and reabsorb the sulfur onto the carbon dioxide gas. The carbon dioxide gas can then be recycled to the synthetic fuels production process with deposition of the sulfur therein or the gas can be delivered for export with downstream sulfur treatment.
