尽管长期的研究，天然气工业中的Ranque效应仍然是未知的。缺乏工业运行数据。没有发现关于天然气发电厂由于朗克效应而达到高温的信息。本文对逆流涡流管内高压天然气的温度分离进行了实验研究。设计了一种工业涡流管，并将其应用于低温分离装置中。结果表明，焦耳-汤姆逊效应对温度分离过程有显著影响，在分析操作数据时应考虑焦耳-汤姆逊效应。在所研究的条件下，只有在非常小的热流质量分数下才能看到显著的加热效应。为了避免液体负载问题，游离气体冷凝物和水应在涡流管之前或直接从其主体中移除。压比的增加导致较大的温差。在几乎所有的冷流质量分数范围内，冷流温降都大于焦耳-汤姆逊效应。在实验中实现了导致郎克效应效率降低的喷射型流动。然而，这种流动也可用于闪蒸石油气的利用。
Despite long period of study, Ranque effect remains unexplored in natural gas industry. There is a lack of industrial operation data. No information was found about achieving high temperatures due to Ranque effect on natural gas plants. In present experimental research, temperature separation in high pressure natural gas stream within a counter flow vortex tube was investigated. An industrial vortex tube was designed and implemented into low-temperature separation plant. It was found that Joule-Thomson effect has significant influence on temperature separation process and should be taken into account when analyzing operation data. Noticeable heating effect under investigated conditions could be seen only at very small hot stream mass fractions. To avoid liquid loading problems free gas condensate and water should be removed before the vortex tube or directly from its body. The increase of pressure ratio leads to higher temperature differences. Cold stream temperature drop is higher than Joule-Thomson effect on almost all range of cold stream mass fractions. The ejecting type of flow was achieved in experiments that causes the reduction of Ranque effect efficiency. However, such flow could also be useful for utilization of flashed petroleum gases.
