FIELD: gas industry; power engineering; refrigerating engineering; plants for utilization of potential energy of gas pressure. SUBSTANCE: proposed plant includes turbo- expander, electric generator mounted on one shaft with turbo-expander and vortex tube whose inlet is connected to line supplying gas to turbo- expander; vortex tube has hot gas flow outlet which is connected to turbo- expander for heating its working surfaces and cold gas flow outlet connected to low-pressure line after turbo-expander; plant is also provided with cooling chamber connected with turbo-expander by means of low-pressure line through separator mounted between them. EFFECT: avoidance of icing of working surfaces and choking of heat exchangers. 2 dwg |
