Reduction of Investment Costs by Improvement of Thermodynamic Efficiency in Cryogenic Systems

摘要

Carefully directed investments to reduce the thermodynamic losses in critical subsystems often lead to a reduction of the overall investment costs, This is demonstrated by recent developments in the technology of low temperature refrigeration. By replacing the Joule-Thomson valve by a work extracting expander and other modifications of the cycle, operating costs are reduced by 40% and investment costs by 20%.
