Modeling of Gaseodynamic Processes at a Pressure Reduction Point with the Use of a Volumetric Expander−Generator Set to Assure Safe Recycling of the Energy of Compressed Natural Gas

Resumo

A variant of a modified design of a pressure reduction point with built-in volumetric expander−generator set is considered. A mathematical model of the dynamics of the processes associated with expander−generator sets by means of which the influence of the sets on the gaseodynamics of the reduction points may be estimated is developed. The results confirm that safe recycling of compressed natural gas energy is possible in the course of pressure reduction even with high degree of irregularity of gas consumption.
