What do you think about TEG regeneration alternatives (i.e. Drizo, Coldfinger, etc.)in terms of advantages and disadvantages vs. the stripping gas common method employed?
I think they have licenses for all the different TEG process and as such I am sure they could point you in the right direction with pros and cons for each one
I think you will find that each system has its advantageous and disadvantageous and therefore the selection will depend on you detailed process requirments/cost analysis/environmental issues etc
Unless you are looking for a 100 Deg F dew point depression, there is no need for patent medicines on TEG units. A simple Stahl Column will get the extra drying needed for a large dew point depression. QB Johnson is a packager in Oklahoma City that ships units world wide.
If you are in an enviromentally sensitive area, don't forget the BTEX.
