The HME Ammonia Synthesis Enhancement is a simple process modification enhancing synthesis productivity by reducing energy consumption and/or increasing plant capacity as compared to conventional alternatives. In this paper, it is presented as an attractive alternative to low temperature ammonia separation in low pressure plants.
Some HME performance sensitivities and their implications on the design of a unit are studied. Typical HME enhancement economics is summarized in comparison with a typical conventional alternative. This indicates a potential 25% reduction in refrigeration power consumption, paying out the HME unit in a relatively short time. The application of the HME enhancement is expected to promote synthesis at lower pressures.
