A new algorithm of mass flow rate determination in gas production and transportation systems via pressure measurement

Resumo

The current algorithm for calculating mass flow rate in gas production and transportation systems from outlet pressure measurements is generalized to the case where the inner cross section of the pipe changes with time and is also to be determined in the course of solving the general problem. The generalized algorithm is recommended for identification of gas hydrate formation in the above-mentioned systems. The identification of hydrates in a main gas pipeline in permafrost is considered as an example.
