The method of convective heat transfer in order to prevent the formation of solid gas hydrate plugs in the pipeline

摘要

1. A method for convective heat transfer to prevent formation of solid gas hydrate plugs in the underground pipeline in the case of transporting natural gas by pipeline, comprising the supply of thermal energy to it in order to maintain the required minimum positive temperature preventing gas-hydrate from ehnergotehnologicheskoj installation gaseous fuel by the tubular water cooler characterized in that the water pipe radiator, consisting of two parallel and adjacent meth llicheskih pipes is much smaller than the diameter of the pipeline and connected together at the end in the form of a semiellipse, feed pipe heated by a 50% aqueous solution of antifreeze and outlet of the other tube-cooled 50% aqueous antifreeze solution is located inside the bottom of the pipeline with external thermal insulation and waterproofing obolochkoy.2. The method of claim. 1, characterized in that to facilitate and simplify installation and dismantling, significantly reducing the corrosion of the water pipe of the radiator in the case of land transportation of natural gas through the heat sink mounted externally of the pipeline and is secured by means of metal clamps close to the bottom of the pipeline at its outer insulating and waterproofing membrane.
