| titleOfInvention | A kind of separation method of methanol to olefins reaction gas |
| abstract | The present invention relates to a kind of separation methods of methanol to olefins reaction gas.This method is using the component of the hydrocarbon containing C4-C5 as light components such as methane in absorbent methanol removal alkene (MTO/DMTO) reaction gas, and methane and light fraction in 30 DEG C or more operation temperature section methanol removal alkene (MTO/DMTO) product gas effectively inhibit water and hydro carbons to form hydrate.In addition, drying process of the invention does not need to be placed on compression unit outlet, it only needs that deethanizer overhead gas is dried, it avoids and compression unit outlet liquid phase lime set is dried, drying process treating capacity is significantly reduced, considerably reduces the consumption and energy consumption of public work nitrogen therewith.Demethanation process is switched to thermal release process and is conducive to heat exchange network optimization by this method, does not need -40 DEG C of cryogens below of investment.With the features such as small investment, material recovery rate is high. |
