Given the Joule-Thomson coefficient for methane equal to 0.5°C/bar, calculate the minimum temperature at which it is advisable to heat the gas at a city gate where it is throttled from 50 to 3 bar (relative pressures). If the inlet temperature is 15°C, and given the heating value for methane Hu= 48500 kJ/kg and its specific heat cP=2.4 kJ/(kg K), calculate the amount of gas that must be burnt (as % of the overall gas flow).
