Abstract:
Production of High-Purity Liquid Ammonia
Phase I will determine the feasibility of using an innovative combination of molecular
sieves in the gas phase and then in water solution for the purification of refrigeration-grade
ammonia. The purified product will then be compressed to the liquid phase with an
oil-less compressor. This will result in a high-purity grade of liquid ammonia that
surpasses the requirement of the current shuttle-grade of anhydrous ammonia (fluid
specification SE-S-0073). This project will build a laboratory processing unit and
verify its ability to produce high-purity liquid ammonia from refrigeration-grade
material. Information gained from Phase I will be used in Phase II to build a pilot-plant-scale
production unit at the Kennedy Space Center, sized to meet the current requirements
of 3000 lb per year.
The firm will be able to market their design for the production of high-purity liquid
ammonia. Applications of the design could include small metal-finishing shops.
