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.
