At the base of the ATR, the remaining methane reacts endothermically
with the steam over a fixed catalyst bed. This reforming process may be
summarized as follows:

10. The most important advantages :
- Very low production cost.
- High syngas conversion efficiency at the same overall conversion.
- High energy efficiency:
- Large single-train capacity:

11. 3- Lurgi's Mega-Methanol Technology for MTP:
The term "Mega-Methanol" refers to plants with a capacity of more than one million
metric tons per year. To achieve such a large capacity in a single-train plant a special
process design is required. For this reason Lurgi focused on the most efficient
integration of syngas generation and methanol synthesis into the most economical and
reliable technology for the new generation of future methanol plants.

13. Requirements & Conditions:
• Pressure (1.3-1.6 Para),
• Moderate steam addition (0.5-1.0 kg per kg of methanol)
• Low reactor inlet temperatures (400-450°C).
• Catalyst has to be regenerated after a cycle of approx. 400-700 hours of
operation.

14. Health and Safety Considerations
Heath and safety comparison
• Propylene is the only reactive
product
• Reactant and products have high
level of flammability
• None of the products nor reactant
have special hazard.

15. Health and Safety Considerations
Personal Protective Equipment (PPE)
• Coverall
• Safety glasses
• Safety boots
• Gloves
• Helmet
Plant Design Safety:
• Gas Detectors
• Fire Prevention Equipment
• Fire Fighting Equipment

16. Environmental Considerations
• The main concern associated with releases of Propene is that, as a VOC, it may be
involved in the formation of Ozone.
• It is not considered likely that Propene pollution has major effects on the global
environment.
• Methanol occurs naturally in the environment as a result of various biological
processes in vegetation microorganisms, and other living species.
• Methanol is completely miscible in water.
