To obtain such a detailed comparison, one needs to find fellow sailors with relevant resources; it’s generally not easy to get access to information that comprehensive.
To find this kind of information, one needs to look for the feasibility study report for the MTO project……
There is not much difference among MTO technologies; UOP’s MTO has a relatively wide E/P range, typically between 0.6 and 1.4. However, it is still necessary to decide in advance whether more propylene or ethylene should be produced, while for other cases the E/P value is 1–1.1.
1. There is little difference in MTO technologies; UOP’s MTO has a wider E/P range, typically between 0.6 and 1.4, but it is still necessary to decide before design whether to prioritize the production of propylene or ethylene, with other options having an E/P value of 1–1.1. 2. OCC is primarily used for the cracking of C4 hydrocarbons to produce propylene, while OCP is used for cracking C4 hydrocarbons to produce both propylene and ethylene. OCU involves the reaction of ethylene and C4 olefins to produce propylene. DMTO-2 adds an additional C4 reaction and regeneration system, enabling the co-production of propylene and ethylene from C4–C6 hydrocarbons. However, in terms of product distribution and market economy model, OCP and DMTO-2 are more competitive. It is not convenient to disclose the specific figures here
