MeOH 4

• Com bustion:

H2 + 1/ 2O2 = H2O Hrx = -242 kJ/ mol

• Reform ing and W ater Gas Shift:

Gas from prim.ref. Oxygen + H2O Burner

Secondary Reformer

• Reform ing and W ater Gas Shift:

CH4 + H2O = CO + 3H2 Hrx = 206 kJ/ mol CO + H2O = CO2 + H2 Hrx = -42 kJ/ mol

• Energy:

Heat is recovered in a Waste Heat Boiler (Steam)

• Catalysts:

Synthesis gas + H2O MeOH 5

Methanol Synthesis

• Chem ical Reactions:

CO + 2H2 = CH3OH Hrx = ?? kJ/ mol CO2 + 3H2 = CH3OH + H2O Hrx = ?? kJ/ mol

• Heat of Form ation Data:

CO : H0

f = -111 kJ/ mol

CO2 : H0

f = -393 kJ/ mol

H2 : H0

f = 0 kJ/ mol

MeOH 6

CH3OH : H0

f = -201 kJ/ mol

H2O : H0

f = -242 kJ/ mol

Answer: -90 kJ/mol and -50 kJ/mol  Exothermic Reaction

• Stabilizer:

Distillation Section with 3 Columns

Removes lighter Components in raw Methanol before Distillation

• HP Column:

45 % of the Distillation

• LP Column:
• LP Column:

Completes the Purification
