One of the important tasks for the Russia’s economy and ecology is development and realization of energy and&#x0D;resource saving technologies, allowing the most efficient use of both primary and secondary resources. In oil, gas and&#x0D;chemical industries are widely used processes, in which the potential energy of hydrocarbon or waste gases pressure&#x0D;is either loosing, either recycling with minimum efficiency. The loosing energy should be used for low-temperature&#x0D;purification of waste and prepared gases, thus reducing environmental pollution. One way to solve this problem is&#x0D;to use a vortex technology based on the Rank-Hilsch vortex effect. By efficiency this purification method exceeds&#x0D;manifold standard throttling systems. In this review an analysis related to both theoretical and technological aspects&#x0D;of vortex effect research has been presented. Vortex tubes’ different constructions have been considered along with&#x0D;the incoming flow regulation as the one of the important conditions for these tubes’ operation and realization in&#x0D;the industry. It has been shown that the realization of the regenerative scheme with vortex tubes will improve the&#x0D;core technology’s ecological and economic indicators. A critical review of existing theories related to the Ranque-&#x0D;Hilsch effect has been presented. The development prospects of vortex effect’s shock-wave mechanism allowing&#x0D;explain the excessive cooling capacity of triple-flow vortex tubes used for associated petroleum gas preparation for&#x0D;transportation have been considered.
