In low pressure natural gas distribution networks altitude affect can have an impact in regular operations: pressure increases with the density of the natural gas at high altitudes and decreases at lower ones, which can take the operating pressure out of the standard and safety limits. A typical solution has been to separate the network into two or more independent parts leading to a reduced impact of the altitude effect in each section. This is a drastic solution that does not solve the problem and sometimes cannot be applied.
This paper presents a solution based on the dynamic pressure regulation that can be used profitably in these situations
