Liquefied gas pipeline transportation
Thread Content
Liquefied gas is transported in liquid form; are there any examples of pipeline transportation over long distances (about 20 kilometers)? At the same time, is it necessary to return the gas phase as well? If no gas-phase return line is provided, what are some reasonable measures for making use of it? I hope experts can provide some guidance! Thank you!
Just pull out the bottom of the tank and pump it; I don’t understand what happens with the gas phase – where does that gas phase come from? We have a propane pipeline here that is about 5 km long, leading to the ethylene plant; it involves pumping, and insulation for the pipeline is sufficient. Check valves and safety valves are installed before it connects to the main pipe of the receiving unit. As for the 20KM version, I really haven’t seen it. By the way, long-distance pipelines need to be inspected daily.
Thank you for the reminder; I will make sure to increase my daily inspections of the lines.
It is sufficient to control the back pressure of the pipeline; as long as it is not lower than the saturated vapor pressure of the liquefied gas, the substance will remain in liquid state. This also reduces corrosion in the pipeline, and of course, proper insulation measures must be taken.

Are there any regulatory requirements regarding which substances can be transported over long distances via pipelines? ? For example, can propylene oxide be transported over long distances? ?
