Abstract : This project was a continuation and refinement of a feasibility prototype natural gas liquefier that had been designed, fabricated, and tested under a U.S. Department of Energy (DoE) Small Business Innovation Research (SBIR) contract. Extensive performance testing was conducted to characterize the natural gas liquefier refrigeration capability and to collect data for diagnostic purposes. Analysis of the effectiveness of the regenerator concluded that the current design would require substantial empirical iterations. The final prototype with a design target of 1,000 Watts (W) refrigeration was able to achieve only 400 W of refrigeration, projected to 550 W at a higher charge pressure. Recommendations are made for further testing, analysis, and correlation to achieve a better optimized regenerator design for a second generation prototype natural gas liquefier. jg
