  • Publication number: 20200078728
    Abstract: A raw syngas coming from HT gasification of organic wastes, once cooled in a proper heat recovery boiler or in a quencher is treated in a scrubbing section where, by adding an acidic solution followed by alkaline solution and by a WESP, particulate and chlorine compounds are removed and the syngas is ready for conversion, after its compression. In the conversion step CO is converted into C02 and H2 by adding steam; H2S is reduced to sulphur in a solid form, C02 is removed via cryogenic unit or an amine unit and pure H2 is produced.

  • Patent number: 9802820
    Abstract: The present invention relates to a plant for performing a method for hydrogen production or for performing a method of hydrogen and/or carbon dioxide production from syngas. The method comprises the steps of: (i) providing a gas stream comprising hydrogen and carbon monoxide, (ii) separating at least part of hydrogen from the stream yielding a hydrogen-depleted stream, (iii) subjecting the hydrogen-depleted stream to a water-gas shift reaction, and (iv) separating hydrogen from the stream resulting from step (iii).

  • Patent number: 9776863
    Abstract: The present invention relates to a method for hydrogen production and to a method of hydrogen and/or carbon dioxide production from syngas. The method comprises the steps of: (i) providing a gas stream comprising hydrogen and carbon monoxide, (ii) separating at least part of hydrogen from the stream yielding a hydrogen-depleted stream, (iii) subjecting the hydrogen-depleted stream to a water-gas shift reaction, and (iv) separating hydrogen from the stream resulting from step (iii). The method according to the invention improves the conversion of carbon monoxide in the water gas shift reaction and allows to increase the hydrogen production by 10-15% and to increase the overall energy efficiency of the system by 5-7%. The invention further relates to a plant for hydrogen and/or carbon dioxide production suitable for the method of the invention.

  • Patent number: 9701535
    Abstract: Disclosed is a process for the production of a syngas mixture by catalytic partial oxidation. The syngas mixture is suitable as an intermediate in the production of hydrogen. According to the invention, the syngas is cooled, prior to a water gas shift reaction, with liquid water. This has the advantage of avoiding the problem of metal dusting, and it presents a gas mixture comprising water vapor that is particularly suitable for a water gas shift reaction in the production of hydrogen.

  • Patent number: 9598290
    Abstract: Disclosed is a process for the production of ammonia comprising a step wherein synthesis gas is formed by catalytic partial oxidation. Also disclosed is a process of producing urea, wherein ammonia is formed in a process involving a step of catalytic partial oxidation, and carbon dioxide formed in the same process is reacted with said ammonia so as to form urea.

  • Patent number: 9394219
    Abstract: Method for producing synthesis gas for methanol production The present invention relates to a method for producing synthesis gas from a hydrocarbon containing feed, which synthesis gas is particularly suitable for subsequent use in methanol production. In this method, a hydrocarbon containing feed, particularly natural gas (100), is subjected to catalytic partial oxidation (CPO) (2), followed by the water gas shift (WGS) (4) reaction of a part of the reformed feed. At least part of the shifted feed is then subjected to hydrogen purification, preferably by pressure swing adsorption (PSA) (5) to obtain pure hydrogen (108), which hydrogen is subsequently combined with the remaining parts of the feeds to yield synthesis gas particularly suitable for methanol synthesis. The recombined stream preferably has an R ratio, being the molar ratio (H2?CO2)/(CO+CO2), in the range 1.9-2.2 and preferably about 2.

  • Patent number: 9340494
    Abstract: Disclosed is a process for the production of ammonia comprising a step wherein synthesis gas is formed in two different ways, viz. by catalytic partial oxidation (31) and by steam reforming, and wherein the combined streams of synthesis gas are subjected to a water gas shift reaction (50). Also disclosed is a process of producing urea, wherein ammonia is formed (90) in a process involving said combined streams and wherein carbon dioxide (110) formed in the same process is reacted with said ammonia so as to form urea.

  • Patent number: 9102532
    Abstract: Method for producing synthesis gas for methanol production The present invention relates to a method for producing synthesis gas from a hydrocarbon containing feed, which synthesis gas is particularly suitable for subsequent use in methanol production. In this method, a feed (100) is divided into two streams, wherein one stream is subjected to catalytic partial oxidation (CPO) (2) and the other stream is subjected to steam reforming (5) followed by a water gas shift reaction (51). The two streams are then recombined and can be used further in methanol synthesis (6). The recombined stream preferably has an R ratio, being a molar ratio (H2?C02)/(CO+C02), in the range of 1.9-2.2 and preferably about 2. The invention further relates to a method for producing methanol from a hydrocarbon containing feed, wherein first synthesis gas is obtained according to the method of the invention, which synthesis gas is further used to produce methanol.
