Methanol to olefins and methanol to propylene is a chemical technology to produce light olefins. This technique employs coal to methanol as the raw material and is with the aid of fluidized bed reaction form similar to catalytic cracking unit. Currently, the foreign representative of the MTO process technology mainly: UOP / Hydro, ExxonMobil's technology, and Lurgi of MTP technology. For the above process, we have a deep understanding. And we can provide comprehensive solutions and technology packages.



 The flow chart of MTO olefins separation techniques
 
The advantage of MTO olefins separation technologies:
         Adopt pre-cut & oil absorption technology to replace traditional cryogenic demethanization system, with simple flow, without cryogenic separation units and ethylene refrigeration compressor, few equipment investment and low energy consumption;
         Adopt effective methods of depriving light gas such as nitrogen, oxygen gas, CO and DME, with simple and reliable flow as well as strong adaptation to the component changes of the raw material;
         Adopt advanced technology and reasonable design to ensure the high efficiency of ethylene and propylene in case of low energy consumption;
         Adopt effective measures to prevent coking and scale formation in the system as well as safety precautions so as to ensure the safe and stable operation of the plant for a long period;
         Overall process is integrated and optimized by general units as all units have successful experience on production and operation while with safe and reliable technology and free from the risk of industrialization.
