Application of Vortex Technology for Purification of Vinyl Chloride Production Waste

Abstract

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.
