An analytical study of TEG loss in a natural gas purification plant based on high-pressure droplet angular scattering

Guangyao Lin, Fei Hu, Zhen Liu, Zhongli Ji et autres

In the process of purifying natural gas, natural gas dehydration plants use triethylene glycol (TEG) as a solvent for absorption. However, the loss of TEGs in the form of droplets can pollute pipelines and create a technological challenge. Using the geometric optical …
