    摘要： A process for the gasification of a solid carbonaceous feed, the process comprising the steps of: introducing a batch of the solid carbonaceous feed into a sluice vessel, while an internal pressure in the sluice vessel is at a first pressure; introducing at least recycled CO2 into the sluice vessel via one or more gas inlets covered by the solid carbonaceous feed, to pressurize the sluice vessel from the first pressure to a second pressure exceeding the first pressure, during a predetermined time period; closing the one or more gas inlets; opening a feed outlet of the sluice vessel to supply the batch of the solid carbonaceous feed to a feed vessel for feeding the solid carbonaceous feed to a gasification reactor; closing the feed outlet; venting the sluice vessel to reduce the internal pressure to the first pressure; and repeating the process.

    摘要： A method and an apparatus for removing acid compounds (sweetening) and moisture (dehydration) from a hydrocarbon gas, in particular from a natural gas or from a refinery gas fraction or a gas of synthesis, by subsequent absorption operations using a sweetening liquid and a dehydration liquid. The method comprises a step of prearranging a sweetening chamber (51) and a dehydration chamber (52) within a vertical elongated container (50), each chamber defined by an inner partition wall (68) of said vertical elongated container (50), is wherein a gas transfer passageway (14) is provided between an upper outlet port of the sweetening chamber (51) and an inlet port of the dehydration chamber (52); the method also comprises steps of feeding the absorption liquid from the above into the two chambers and of feeding the gas from below into the sweetening chamber. The apparatus and the method according to the invention make it possible to reduce the overall dimensions of the treatment unit with respect to the prior art units, which is particularly relevant for off-shore installations.
