Abstract
Heating of natural gas on the gas-distributive installations is carried out for prevention of creation of gas hydrates in gas pressure controller. There are a few methods of heating of natural gas: complete heating of gas and heating of gas pressure controller. The indicated methods have a row of failings, the delivered from which is possible at the use of vortex tube. Work of vortex tube consists of the simultaneous making of two streams: heated and frappe. The heated stream is used for a serve on a gas pressure controller which shuts out it freezing. Little price, insignificant sizes, absence of motive details helps to use a vortex tube for heating of natural gas on the gasdistributive installations.
