What is it about?

The paper proposes a novel thermoacoustic cooler that utilizes a bypass expansion configuration for distributed-temperature heat loads. This technique enables the cooler to carry out multiple refrigeration processes, achieving cooling at different temperatures across various areas. This approach allows for the cascade processes of natural gas liquefaction, ultimately leading to improved efficiency.

Why is it important?

Natural gas is a popular choice for reducing carbon emissions because it produces fewer greenhouse gases and is very efficient. This has led to an increased interest in compact and reliable ways to turn natural gas into a liquid, making it easier to store and transport. However, traditional methods for liquefying natural gas are often too big for small-scale operations. Thermoacoustic technology offers a promising solution to this problem because it has a simple design, is very stable and reliable, and is environmentally friendly.


This publication provides a simple and reliable new cascade refrigeration process that will exert a positive impact on a wide range of liquefied gas processes, especially the precooling process.
