Significance of Desorption and Regeneration:

Adopting the way of oxidation or recovery to process the high-volume low-concentration VOCs directly,it not only need large dimensions of equipment,but also high energy consumption, so it's not economic.For this problem,it can use concentration equipment to concentrate low-concentration high-volume waste gas to high-concentration lowv-olume one. Then it enters the subsequent oxidation or recovery unit to be processed to decrease equipment investment and running cost.
