Methanol-to-Olefins (MTO) Process

Client：A leading enterprise in the fine chemical industry

Daily Treatment Capacity：300m³

Source of Treatment Solution：

The Methanol-to-Olefins (MTO) process converts methanol into light olefins such as ethylene and propylene through catalytic reactions.
During the stages of quenching, water scrubbing, and stripping, the reaction gas generates aldehyde–ketone condensates mixed with fine catalyst powder.
If not properly removed, these condensates and catalyst particles re-circulate within the reaction system, causing heat exchanger blockages, operational instability, and a decline in conversion efficiency.
The resulting process liquid is characterized by high temperature, high COD (due to large amounts of aldehydes and ketones), and fluctuating oil content, making it difficult to treat using conventional separation technologies.
By adopting the CASAIS Aggregation-Induced Separation process, the plant achieved efficient and stable oil–water separation, effectively preventing catalyst fouling and maintaining system reliability.
The solution provided by CAS-REALNM ensures continuous operation, improved heat exchange performance, and significantly reduced maintenance frequency, supporting stable production of high-purity olefins.

Treatment Effect

Processing comparison：The liquid output remains stable even when there are fluctuations in the liquid input.
