Can a absorption refrigeration system be used to cryogenic purposes?

07 October 2024 0 7K Report

Hello,

I am considering feasibility of utilizing absorption refrigeration systems for cryogenic LPG recovery. My goal is chilling the sweet natural gas to -60 c to increase LPG recovery. I would also like to know if there any suggestion other than water/ammonia for fluid pair's.
