Methanol plant, energy balance

Adopting 4,770 kcal/kg for the low heat value of methanol and considering the case of a Winkler type gasifier, the energy balance of the plant would be as shown in Table III ... 

Energy Balance of Methanol from Wood Plant... 

A 300 MW IGCC power plant with electricity and methanol cogeneration has been proposed where 88 % of the carbon introduced by the coal can be extracted as CO2 with an acceptable amount of energy and investment cost which is partially utilized in combination with H2 from an external carbon-free source for methanol production. The overall balance for a 354 MW power plant (234 MW for the gas turbine and 120 MW for the steam generator) is an input of 2300 t of coal, 780 t of hydrogen, and 5500 t of CO2 (as intermediate product) per day to achieve a daily output of 3800 t of methanol and a total net power output of 310 MW [44].
