Question: What is the purpose of installing a water washing section in the alkali washing tower of an olefin plant? It is to prevent alkali solution from entering the system, as liquid alkali can cause \"alkali embrittlement\" in the compressor impellers.
The purpose of installing a water washing section in the alkali scrubber tower of the olefin plant is to remove oxides using purified water.
Enter the water scrubber tower to remove the entrained oxides
To prevent alkali solutions from entering the system, liquid alkali can cause \"alkaline embrittlement\" in the compressor impeller”
Washing towers are used to remove oxidized compounds, such as methanol, dimethyl ether, ethanol, propanal, and propionaldehyde
Answer: Wash away the residual alkali left after the alkaline cleaning； Prevent alkaline solutions from entering the system, as liquid alkali can cause \"alkaline embrittlement\" in the compressor impeller.
