Advantages of pre-lifting of dry gas
Thread Content
What are the advantages of using dry gas lift? What impact does it have on the reaction? I hope you can all give me some guidance
Dry gas is generally a better choice as the lifting medium, as its main advantages include reducing steam consumption and preventing hydrothermal deactivation of the catalyst; moreover, the hydrogen in dry gas can effectively lower the olefin content in gasoline. The downside is that it increases the load on the air compressor; if the compressor’s load is insufficient, it is best not to use it.
Currently, dry pre-heating is used for catalysis; that is, steam is employed at the beginning of operation, while dry gas is used once normal production begins. The first advantage is energy savings and reduced consumption； The second advantage is: reducing catalyst damage ； The third advantage is: catalyst sulfidation is more effective than steam treatment.
