One of the important tasks of the Russian economy and ecology is development and realization of energy-saving technologies, allowing the most efficient use of both primary and secondary energy resources. In oil, gas and chemical industries, there are processes, in which the potential energy of pressure of hydrocarbon or waste gases is either lost, either recycled with minimum efficiency. The energy lost should be used for low-temperature purification of waste and prepared gases, thus reducing environmental pollution. One way to solve this problem is to develop a vortex technology based on the Rank-Hilsch effect. By efficiency this method of purification exceeds standard throttling systems. This review presents an analysis of both theoretical and technological aspects of research of the vortex effect. different constructions of vortex tube are considered along with the one of the important conditions of its operation and realization in the industry - regulation of the incoming flow. It is shown that the realization of the regenerative scheme with vortex tubes will improve ecological and economic indicators of the core technology. A critical review of existing theories of the Ranque-Hilsch effect is provided. The article reviews the prospects of development of shock-wave mechanism that allows to explain the excessive cooling capacity of triple-flow vortex tubes used for associated petroleum gas treatment.

The practical aspects related to application of three-flow vortex pipes in the systems of low-temperature separation of associated petroleum gas before its giving in the main pipelines are considered in this paper. The conclusion is drawn that due to the use of these pipes the extinguishing of field torches is becoming rather profitable, improving thereby the ecological situation while developing of oil fields.

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

The settlement assessment of Ranque—Hilsch vortex pipes application for low-temperature purification of vinyl chloride production waste gases has been presented. It is shown that implementation of the recuperative scheme with vortex pipes will allow to improve ecological and economic indicators of the main chemical technology. Bench tests of vortex generators of cold as a part of the industrial unit gave the chance to receive their thermodynamic characteristics on real waste gas and technical nitrogen. It is established that in lack of the recuperative heat exchanger a condensation of vinyl chloride vapors proceeds in vortex pipe itself. Application of a three-line vortex pipe is recommended in case of need. At research of not adiabatic vortex pipe cooled by a coolant, it has been established an experiment divergence with the theory of micro refrigerating cycles. It is offered to explain the arisen contradiction from a position of shock and wave mechanism of Ranque—Hilsch effect developed by authors.
