Nitrogen protection issue for hydrogenation feedstock

2017-04-14View Original

Thread Content

Hydrogenation feedstocks require nitrogen protection to prevent aromatic thiol compounds and olefins in the feed oil from oxidizing upon contact with air, which would lead to the formation of sediments and gums and increase the pressure difference in the reactor. Therefore, is it necessary to install nitrogen seals in the chemical storage tanks (polymerization inhibitors) and water injection tanks of the hydrogenation system?
