Are these "solvent extraction processes"? Are thermocompressors or steam jet ejectors even needed for these processes?

If so where exactly do they come into play? A schematic would be extremely helpful.

Thanks!

Sulfinol is the solvent used for acid gas removal - mainly for natural gas plants. It is comprised of physical solvent component (Sulfolane), chemical solvent (MDEA or DIPA amines), and water. See attached process schematics.

As a conventional absorber-regenerator type of unit, it does not employ jet ejectors.

What if it wasn't a conventional absorber-regenerator type unit? Are there other types of units that may require a jet ejector?

I have seen that jet ejectors can be used for solvent extraction purposes in general, but I am having a hard time figuring out exactly where they come into play and which solvent extraction processes they are used for. Are there any other chemicals that require solvent extraction for their production that would need a jet ejector?

sarah,

The manufacture of PET polyester requires vacuum generation using multi-stage steam ejectors. For large capacity plants, the ejectors are quite big with medium pressure (150 psig) steam consumption of the order of 2000-3000 lb/h.

For various applications of steam ejectors see the following links:
