Description of Acetaldehyde Production Process

Acetaldehyde production includes 3 primary process: acetylene hydration, ethylene oxidation, and alcohol oxidation. Helipont currently utilizes the alcohol oxidation process for the production acetaldehyde, because alcohol features a low costs and a wide usage range. It also features a low conversion rate. We use double towers for absorption- one tower for circulation absorption, and the other for a spraying absorption and recycling plant in order to obtain the best consumption.

Flow chart
Main Equipment for Acetaldehyde Plant
  • Evaporator
  • Oxidation tower
  • Absorption tower
Production Process
  • Mix the alcohol material.
  • After removing impurities such as dust via air filter, the outside air enters the evaporator via the roots blower.
  • Mixed alcohol and air react in the evaporator and generate acetaldehyde.
  • Cool down the acetaldehyde and unreacted alcohol.
  • Rectify the acetaldehyde.
