Tail Gas Treatment Unit for TGTU Process - burnertec.com

A sulfonation plant exhaust gas treatment unit is a critical environmental control system designed to remove hazardous pollutants—primarily Sulfur Dioxide (

cap S cap O sub 2

), Sulfur Trioxide (

cap S cap O sub 3

), acid mists (

cap H sub 2 cap S cap O sub 4

), and organic mist/vapors—before venting to the atmosphere.

The exhaust typically undergoes a multi-stage cleaning process, often employing wet scrubbing technology, to meet strict emission standards for surfactant production (e.g., LABSA, SLES).

Electrostatic Precipitator (ESP) or High-Efficiency Filter:
- Purpose: Removes fine
  $cap S cap O sub 3$
  /
  $cap H sub 2 cap S cap O sub 4$
  mist and organic particles from the gas stream.
- Benefit: Prevents downstream plugging and recovers organic drippings as usable finished product.
Scrubber System (Absorption Column):
- Purpose: The core unit. A packed bed tower where the acidic exhaust gas flows upward against a downward spray of scrubbing liquid.
- Scrubbing Medium: Caustic soda (
  $cap N a cap O cap H$
  ) solution is typically used to neutralize
  $cap S cap O sub 2$
  and
  $cap S cap O sub 3$
  .
- Reaction:
  - $cap S cap O sub 2 plus 2 cap N a cap O cap H right arrow cap N a sub 2 cap S cap O sub 3 plus cap H sub 2 cap O$
  - $cap S cap O sub 3 plus 2 cap N a cap O cap H right arrow cap N a sub 2 cap S cap O sub 4 plus cap H sub 2 cap O$
Gas-Liquid Separator (Mist Eliminator):
- Purpose: Positioned at the top of the scrubber to remove entrained liquid droplets from the cleaned gas before it is discharged.
Exhaust Fan (Blower):
- Purpose: Maintains a negative pressure on the reactor system, drawing the exhaust through the treatment unit.
Circulation Tank & Pump:
- Purpose: Recirculates the caustic solution. The pH is monitored and controlled to ensure efficient removal of acidic gases.
