<p>The present invention relates to the techniques for processing natural gas and is intended for heating expanding natural gas without any artificial heating and using the heat from the surrounding medium. This invention is characterised in that the heat is introduced into the gas flow through a heat exchanger from the surrounding medium, the flow being however previously and additionally cooled as it is fed through a spiral tube. The cold flow is then fed into a heat exchanger for external heat exchange, and is further mixed with the hot flow of the spiral tube.</p> |
