Best Practices for Mitigating Flow Measurement Errors Associated with Hydrate Formation

Operating pipelines at high pressure and low temperature can lead to natural gas hydrate formation, even with modest water content. Hydrate formation is also a growing concern as flow measurement equipment and operators become more accustomed to handling wet gas flow. Hydrate particles can attach to pipe walls, instruments, and other structures within the pipeline, which can then lead to gas measurement errors or instrument failure due to solid particle attachment or high-velocity impacts. Hydrates can also agglomerate and form plugs that can lead to a total flow blockage, which can be a serious safety and operational concern for pipeline operators. This article will discuss the operati
