Transient mechanism model of hydrate slurry flow in oil-dominated flowlines

You-qi chuyun, 2021
In the high pressure and low temperature conditions during the production and transportation of deep-sea oil and gas, hydrate is formed easily, which could cause pipeline blockage.

Design of Natural Gas Pipeline

International Journal for Research in Applied Science and Engineering Technology, 2021
India today has an in depth network of underground pipelines used for the transportation and distribution of gas. Large factories, fertilizer factories and other industrial enterprises are the most consumers in PNG and today, however, with the rise in its popularity, it's currently utilized in the domestic sector similarly as a fuel within the ...

Numerical simulation on deposition evolution of natural gas hydrate in pipeline

You-qi chuyun, 2022
The traditional Euler-Euler fluid model is to predict the flow and deposition of two phases by approximating the hydrate particles as a fluid phase, but does not consider the effect of particle formation caused by phase change in the flow process. Herein,

Hydrate formation in natural gas pipelines [PDF]

WIT Transactions on Engineering Sciences, 2011
Gas hydrates pose a problem to the flow assurance programs in the oil and gas industry. This paper highlights the mechanisms of hydrate formation in natural gas pipelines. Computational Fluid Dynamics (CFD) was used to gain insight in to the mechanisms of water vapour condensation and consequent water accumulation in the lowered sections of a gas ...
