Turbo expander conversion of natural gas high-pressure and thermal power to the electric power

Based on the thermodynamic principles this paper deals with isoentropic gas expansion in Turbo Expander as well as power calculation method during such process. An example of calculation for three characteristic conditions is given, and that for Molve Field well area, Molve-East Gas Station area and Zagreb-East Measuring Reducing Station area. Results are given in Tables and also presented graphically and testify feasibility or application the Turbo Expander of corresponding design under specified conditions
