摘要： A method and system for producing hydrogen using an oxygen transport membrane based reforming system is disclosed. The system of the invention comprises at least two reactors in the form of sets of catalyst containing tubes: a first set of tubes comprising at least one reforming catalyst containing reforming reactor configured to produce a synthesis gas stream, and a second set of tubes comprising a reactively driven and catalyst containing oxygen transport membrane reactor configured to generate and radiate heat to the reforming reactor. The synthesis gas product is further treated in a separate high temperature water gas shift reactor and optionally in a separate low temperature water gas shift reactor. Hydrogen is produced from the resulting hydrogen-enriched gas using hydrogen PSA. A distinctive feature of this OTM configuration is that no portion of the syngas is fed to the OTM reactor, which allows reforming to be conducted in the reforming reactors at much higher pressures. The synthesis gas stream is directed to the water gas shift (WGS) reactor where H2/CO ratio increases from about 4.7 to about 21. Since the WGS reaction is exothermic, the shifted syngas leaves the reactor at a higher temperature, typically about 410°C. This shifted syngas is used to heat the NG feedstock in the NG heater to about 370°C, and then used to preheat boiler feed water (BFW). Syngas leaving the BFW heater is at about 175°C. It is cooled down to about 40°C in a syngas cooler fed by cooling water. The cooled syngas then enters a knock-out drum where water is removed from the bottoms as process condensate and recycled for use within the process.

摘要： This invention relates to methods and systems for reliable ultra-high purity (UHP) helium gas supply and maintaining dedicated onsite inventory. Specifically, the invention employs multiple ISO containers whereby vaporized UHP helium in the standby ISO container(s) is used to build-up pressure in the online ISO container. The thermal shields of the ISO containers can be used to decrease heat leaks into the backup ISO container thereby decreasing helium vaporation rate and the amount of gas needed to be withdrawn in order to maintain the maximum allowable working pressure (MAWP) of the vessel. An even lower supply rate is possible by drawing UHP helium gas using an economizer valve but maintaining liquid in the ISO container. This makes it possible to efficiently manage the supply rate, from low flows to higher flow requirements, and to optimize UHP helium draw rate from the storage vessels. A further advantage is that UHP helium gas sent to the customer is of higher purity since it comes directly from a liquid source. The UHP helium gas can be used in semiconductor manufacturing, e.g., as a carrier gas to introduce precursors into deposition chambers during thin film deposition on the wafers.
摘要翻译：本发明涉及用于可靠的超高纯度（UHP）氦气供应和维护专用现场库存的方法和系统。具体地说，本发明采用多个ISO容器，其中备用ISO容器中的汽化UHP氦被用于在在线ISO容器中建立压力。 ISO容器的隔热罩可用于减少备用ISO容器的热量泄漏，从而降低氦蒸发速率和需要抽出的气体量，以维持容器的最大允许工作压力（MAWP）。通过使用节能阀抽取UHP氦气，但在ISO容器中保持液体，可以实现更低的供应速度。这使得可以有效地管理从低流量到较高流量要求的供应速率，以及优化来自存储容器的UHP氦抽出率。另一个优点是，由于直接来自液体源，发送给客户的UHP氦气具有更高的纯度。 UHP氦气可以用于半导体制造，例如作为载气，以在薄膜沉积在晶片上时将前体引入沉积室。
