Methanol is currently produced on an industrial scale exclusively by catalytic conversion of synthesis gas according to the principles of the low-pressure (LP) methanol process (5-10 MPa).
The main advantages of the low-pressure processes are lower investment and production costs, improved operational reliability, and greater flexibility in the choice of plant size. All commercial methanol processes employ a synthesis loop.
This configuration overcomes equilibrium conversion limitations at typical catalyst operating conditions. A recycle system that gives high overall conversions is feasible because product methanol and water can be removed from the loop by condensation.
The makeup synthesis gas is compressed, mixed with recycled gas, and preheated against the converter effluent gas before entering the converter. The converter effluent is first used to heat the saturator water or boiler feedwater before being returned to the loop interchanger and then on to a cooler, which condenses the crude methanol-water mixture. Noncondensable gases are disengaged in a catchpot for recycle. A purge is taken from this recycle to remove excess hydrogen, methane, and other inerts. The crude methanol mixture is sent forward to the distillation section for the final purification.
By high-pressure catalytic synthesis from carbon monoxide and hydrogen; partial oxidation of natural gas hydrocarbons; several processes for making methanol by gasification of wood, peat, and lignite have been developed but have not yet proved out commercially.
Isolation and Evacuation: As an immediate precautionary measure, isolate spill or leak area for at least 50 meters (150 feet) in all directions.
SPILL: Increase, in the downwind direction, as necessary, the isolation distance shown above.
FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions.
Spillage Disposal: Evacuate danger area! Consult an expert! Remove all ignition sources. Ventilation. Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT wash away into sewer. Collect leaking and spilled liquid in covered containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Wash away remainder with plenty of water. Store and dispose of according to local regulations.
Cleanup Methods: Personal precautions, protective equipment and emergency procedures: Wear respiratory protection. Avoid breathing vapors, mist or gas. Ensure adequate ventilation. Remove all sources of ignition. Evacuate personnel to safe areas. Beware of vapors accumulating to form explosive concentrations. Vapors can accumulate in low areas.
