Integrity and Environmental Safety of Gas Networks

The object of research is gas networks. The problem of sustainability of objects of distribution and gas systems is being investigated. The developed software makes it possible to estimate the gas imbalance in complex gas systems of the network type and the volumes of gas emissions into the external environment in case of emergency situations. The software includes all facilities, their information and detailed mathematical models, which provides non-stationary modeling of gas networks and underground gas storages. A feature of the software is the substantiation of the proposed approaches for the guaranteed detection of gas imbalance in closed gas systems based on flow and pressure measurements. The software has been tested in real operating conditions to assess the hermeticity of subsystems of gas transmission systems and emissions during emergency situations at underground gas storage facilities.
