Silver Catalyst Process Formaldehyde Plant

Currently, the silver catalyst process is the most common formaldehyde process, accounting for about 70% of the various formaldehyde production devices all over the world. According to Helipont’s experience, the improvement for this process is primarily divided into the following two types:

Production Process
  • Multifunctional Evaporator Formaldehyde Plant

    The multi-functional evaporator process is the newest silver catalyst formaldehyde production process, and was independently researched and developed by the Helipont team. This patented process uses two specially designed absorption towers capable of producing 37-55% formaldehyde.
