The Linde Ammonia Concept is a state-of-the-art process for the production of ammonia from natural gas or light hydrocarbons. It is based on a combination of proven process steps. A LAC plant mainly comprises a modern hydrogen plant, a standard nitrogen plant and a highly efficient ammonia synthesis.
In the hydrogen plant, the synthesis gas is purified by pressure oscillation adsorption in a single process step. The pure nitrogen supplied from the nitrogen plant is first mixed with the synthesis gas upstream of the synthesis gas compressor. With the exception of a third-party license for the Ammonia Casale NH3 synthesis, all other steps in the process are based on Linde's own technology.
