New method developed for siting line heaters on gas pipelines

In most onshore gas transmission systems, use of a line heater maintains the flowing mixture temperature above the hydrate-formation temperature.A new analytical technique estimates the appropriate location of the line heaters along natural gas pipelines, applying the general energy equation. An example shows that the proposed technique can be a simple, easy-to-use tool for designing the heating system of a gas transmission line.Gas hydrates are beneficial as both an important source of hydrocarbon energy and as a means of storBut hydrates can also be detrimental to pipeline operating systems by depositing hydrate crystals on pipe walls and accumulating as large plugs, leading to blocked ...
