Abstract: A method for retrofitting an existing steam methane reformer (SMR) for ammonia cracking is provided. In this embodiment, the existing SMR can include a pre-reformer, a desulfurization unit, a furnace, waste heat recovery sections, a water gas shift reactor, a pressure swing adsorption (PSA) unit, wherein the furnace has a plurality of SMR tubes and a plurality of burners. In certain embodiments, the method can include the steps of: providing the existing SMR; taking the desulfurization unit offline such that no fluid flows through the desulfurization during operation; taking the pre-reformer offline such that no fluid flows through the pre-reformer during operation; and adding means for providing a gaseous ammonia stream to the SMR tubes.

Abstract: Systems and methods for reducing or eliminating corrosion of components of a reactor system, including a supercritical water gasification system, are described. The reactor system may include various system components, such as one or more pre-heaters, heat exchangers and reactor vessels. The system components may be configured to receive a reactor fluid corrosive to an inner surface thereof and to separately receive a protective fluid that has a higher density and is substantially immiscible with the reactor fluid. A rotating element may be configured to generate a rotational force that forces at least a portion of the protective fluid to flow in a layer between the reactor fluid and at least a portion of the inner surface, the layer operating to reduce corrosion by forming a barrier between the reactor fluid and at least a portion of the inner surface.
