The Linde Ammonia Concept (LACTM) is a leading edge process for the production of ammonia from natural gas or light hydrocarbons. Based on proven process steps, the LACTM comprises of a hydrogen plant, standard nitrogen plant, and high-efficiency ammonia synthesis.
In the hydrogen plant, the synthesis gas (syngas) is produced through steam reforming and then purified by pressure swing adsorption. High purity nitrogen is delivered from the nitrogen plant and mixed with the syngas upstream of a syngas compressor. Linde’s LACTM is simpler than other traditional ammonia generation processes, leading to investment and operational cost savings. Additional cost benefits can be recognized through the sale of valuable by-products from the nitrogen and hydrogen plant such as oxygen, argon and carbon dioxide. The LACTM has been implemented in capacities from 150 to 1,350 mtpd of ammonia and has proven reliability in large-scale operation.
