1. Chemical Industry

Raschig ring is used to treat acid-containing waste gas (such as sulfuric acid and nitric acid exhaust gas) in absorption towers and scrubbers, and absorb acidic substances through gas-liquid contact.

Typical case: Washing and recycling of hydrogen chloride gas in the chlor-alkali industry.

2. Environmental protection field

Flue gas purification in waste incineration plant: The ceramic raschig ring filler layer can effectively remove particulate matter and acid gas (such as SO₂, HCl) in the flue gas.

Flue gas desulfurization in the metallurgical industry: It is used as a gas-liquid contact medium in the wet desulfurization tower to promote SO₂absorption.

3. Other industrial scenarios

Gas purification: remove impurities such as tar and naphthalene from the gas.

E-commerce waste gas treatment: purify the exhaust gas of corrosive gases such as fluorine and chlorine.
