| Abstract: | Natural gas hydrates is that natural gas and water under certain pressure and the temperature forms the crystal enveloped shape solid state compound. Long -distance natural gas transportation pipeline always have high pressure which cause to hydrates easily. Hydrates may lead to the pipeline, meter and separate equipment block, which is harmful to the long distance transportation. The article summarizes the hydrates formation principle and condition in pipelines, and its physics and chemistry prevention method at present. |
