Homemade liquid nitrogen generator Joule Thomson throttle (2013)
I determined that there was no good tutorial on how the average person can liquefy nitrogen or air. A few references to cryocoolers, which use an internal helium Stirling engine to create a cold head exist, and I even saw one person use this as a means to liquefy nitrogen, allowing the gas to condenses as it passes over the head.
The tutorial will cover all the steps necessary for one to duplicate my work and build a nitrogen gas liquefier. Each page covers a different topic necessary for the process, including temperature measurements, the compressor, precooler, cooler, throttle and reservoir. I successfully liquefied air in sufficient quantities and I plan to show you how this can be done for the home builder.
