Method for removing accumulated liquid in subsea gas pipelines

M.E. Harbizade - Azerbaijan State Oil and Industry University

During the development of gas-condensate fields, the disruption of phase equilibrium and primarily changes in pressure, temperature, and gas humidity cause the formation of gas hydrates in transmission lines. As the route of subsea gas pipelines passes through various terrains, these parameters vary within a wider range, making the development of preventive measures to avoid possible complications of significant importance.
The article investigates the issues of preventing hydrate formation in the subsea gas pipeline of the Umid field. In order to prevent hydrate formation in the gas pipeline, a new method for removing liquid mass has been proposed and calculations have been carried out. The effectiveness of this method has been confirmed through conducting various tests. The proposed approach can ensure continuous and safe operation of the gas pipeline.
