Methanol and Coal To Olefins (MTO / CTO)

Why convert methanol to olefins ?

The methanol or coal to olefins (MTO/CTO) process is produces olefins which can be reacted to produce polyolefins (polymers), in turn are used to make many different plastic materials. The MTO/CTO process is used to produce ethylene and propylene, the two most consumed raw materials in the petrochemical industry. Methanol can first be obtained from coal or natural gas, or it can be synthesized. The MTO/CTO technology is now currently considered as an alternative process to the production of ethylene and propylene from petroleum.

Brazed aluminium heat exchangers (BAHX) used in cryogenic distillation are key equipment to meet the MTO/CTO process requirements in terms of purification of olefins and polyolefins.

Which equipment for this application ?

The cryogenic distillation needed in the MTO/CTO process requires BAHX in order to cool down streams to very low temperatures. They are also used as condensers and re-boilers for distillation columns.

Why Fives ?

Fives provides multi-stream BAHX which can be adapted to all customers' projects, from simple to more complex requests. Fives and its Cryogenics | Energy business line have dedicated teams of design and R&D engineers who can develop tailor-made equipment perfectly adapted to the petrochemical plants using the MTO/CTO technology.
