Wet Scrubber for Chemical Plant Gas Emissions from China
A wet scrubber removes harmful gases and particulates from chemical plant flue gases by contacting them with liquid sprays, often using packed towers or venturi designs. It qualifies for HTS 8421.39.0130 as industrial gas cleaning equipment handling corrosive and toxic streams. This system neutralizes pollutants like SO2 and HCl before atmospheric release.

Import Tips
• Submit corrosion resistance material certificates (e.g
• FRP or stainless steel) for chemical compatibility
• Prepare hazardous material handling plans if scrubber contains packed beds with absorbents
• Document scrubbing efficiency data (removal percentages) for environmental regulatory clearance
