Chapter 20

Gas Hydrate Control

Abstract

Water and hydrocarbon fluids can form hydrate and block oil and gas pipelines, resulting in restrictions to oil and gas transportation through pipelines. Mitigating hydrate formation in pipelines is one of the most important issues in flow assurance. This chapter describes hydrate forming conditions and methods employed in the petroleum industry to effectively mitigate gas hydrate problems in pipeline operations. These methods include water removal, chemical inhibition, thermal insulation, heating, and system depressurization. This chapter also provides guidelines to maintaining pipeline flow efficiency.
