Scrubber type Packed bed / tower scrubbers
 
 

Hygrade designs and manufactures packed tower scrubbers, offering a complete in-house service starting with process and mechanical design through manufacture to installation and commissioning.

Gas absorption within packed towers takes place in one of two ways:
• by physical contact and dissolution of gas in water or
• a scrubbing reaction between the gas and a scrubbing reagent.

The performance and efficiency of a packed tower scrubber is generally dependent upon the following factors:
• the packing surface area over which gas/liquid transfer will occur
• the even distribution of the scrubbing liquor throughout the packing
• gas velocity through the packed bed
• the liquor flow rate through the packed bed

Examples of gases removed by these types of scrubber include:
• hydrogen chloride
• ammonia
• oxides of nitrogen
• sulphur dioxide
• phosgene
• chlorine
• hydrogen sulphide
• amines
• bromine
• nitric acid
• methanol
• formaldehydeain
