Question: What is the function of the deethanizer in the (DMTO) olefin separation unit? It separates ethane and components lighter than ethane from the top of the tower, while the C3 components are obtained at the bottom of the tower! Note: The answer will be announced automatically in two days!
Ethane and the components lighter than ethane are separated from the top of the tower, while the C3 components are obtained at the bottom of the tower
Ethane and the components lighter than ethane are separated from the top of the tower, while the C3 components are obtained at the bottom of the tower
The function of the deethanizer is not only to carry out distillation separation in order to remove the methane and ethane components from the liquid hydrocarbon mixture, but by integrating it with refrigeration separation equipment in the design process, it is possible to increase the yield of propane and simplify the process flow
Ethane and the components lighter than ethane are separated from the top of the tower, while the C3 components are obtained at the bottom of the tower!
The C2 and lighter components are separated from the top of the tower, while the C3 components are obtained at the bottom of the tower.
C3 is separated at the bottom of the tower, while C2 from the top goes to the ethylene tower
It is to separate light components such as ethane and ethylene from mixed hydrocarbons
