The auxiliary source of heat is disposed within the oxygen transport membrane based reforming system proximate to the reforming reactors and comprises an auxiliary oxygen transport membrane reactor or a ceramic burner. 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.

摘要： The present invention provides for a pressure swing adsorption (PSA) process for the substantial removal of H2O and CO2 from a synthesis gas to obtain a multicomponent product gas substantially free of H2O and CO2 with high recovery of the product gas. Further, the present invention provides an integrated process that achieves sufficiently high H2 and CO recoveries such that compression and recycling of the syngas purification PSA tailgas is not necessary to be economically advantageous compared to the conventional processes.

摘要： A process and method for producing liquid fuel product from hydrogen and carbon monoxide containing streams produced by gasifying solid carbonaceous feedstock and steam reforming of light fossil fuels. The gasifier syngas is treated to preferentially remove at least 99% of sulfur containing impurities and less than 50%> of the CO 2 to produce a treated gasifier syngas and a CO 2 enriched gas.

摘要： A method and system for producing a synthesis gas in an oxygen transport membrane based reforming system that utilizes a combined feed stream (200) having a steam to carbon ratio between about 1.6 and 3.0 and a temperature between about 500 °C and 750 °C wherein the oxygen transport membrane based reforming system and associated synthesis production process equipment are substantially free of carbon formation and metal dusting corrosion. The combined feed stream is comprised a pre-reformed hydrocarbon feed (195), superheated steam (180), and a reaction product stream (198) created by the reaction of a hydrogen containing stream (163) reacted with the permeated oxygen at the permeate side of the oxygen transport membrane elements (120).

摘要： The present invention relates to a cold box cycle which allows for independent control of the heat supplied for reboilers associated with the separation columns. More specifically, the invention relates to the tight control of the hydrogen removal separation, thus avoiding the possibility of excess reboiling in this separation. Optimal reboiling also results in a lower temperature of the hydrogen depleted liquid from this separation. As this stream is used to provide a portion of the cooling at the cold end of the primary heat exchanger, lower temperatures facilitate cooling of the incoming syngas feed, reducing carbon monoxide (CO) losses into the crude hydrogen stream from the high pressure separator. Lower CO in the crude hydrogen allows for smaller hydrogen purification equipment.
摘要翻译：本发明涉及冷箱循环，其允许独立控制与分离塔相关的再沸器供应的热量。更具体地说，本发明涉及对脱氢分离的严格控制，从而避免了在该分离中过量再沸腾的可能性。最佳的再沸腾也导致来自该分离的贫氢液体的较低温度。由于该物流用于在主热交换器的冷端提供一部分冷却，较低的温度有助于冷却进入的合成气进料，减少从高压分离器进入粗氢气流的一氧化碳（CO）损失。粗氢气中的低CO允许使用更小的氢气净化设备。

摘要： A method and system for producing methanol that employs both an oxygen transport membrane (OTM) based reforming system together with a more traditional steam methane reforming (SMR) and/or autothermal (ATR) synthesis gas production system is disclosed. The dual mode system and method for producing the synthesis gas in a methanol production process optimizes the efficiency and productivity of the methanol plant by using the OTM based reforming system as an independent source of synthesis gas. The disclosed methods and systems are configurable either as a retrofit to existing methanol production facilities or as an integrated package into newly constructed methanol production facilities.
