Helipont provides a number of metal oxide processes for the production of formaldehyde, with formaldehyde manufacturing equipment to match these processes, as well as offer plant layout and upgrade solutions.

• Methanol pre-evaporator
• Absorption tower

• Send compressed air to the methanol pre-evaporator.
• Send gaseous methanol and air through the reactor that contains the catalyst for a reaction.
• Condense the formaldehyde gas from the reactor into a formaldehyde liquid.

Annotation: For more information on our production processes, please do not hesitate to contact us.

Compare the metal oxide process and silver catalyst process on the economic front (assume 100,000 tons).

• Equipment: The metal oxide process requires a larger upfront investment in order to produce the same 55% formaldehyde solution.
• Steam output: metal oxide process, 800 kg/MT（2.0Mpa), while silver catalyst process 550 kg/MT（0.6Mpa). Assuming the steam unit price is $22/ton, metal oxide processes save $550,000/year.
• Methanol consumption: metal oxide processes save 20kg/TPA of methanol. Assuming the unit price of methanol is $430/t, metal oxide processes save $860,000/year.
• Service life of the metal oxide processing equipment is more than 50 years, which is almost 3 times longer than equipment used in the silver catalyst process. This means that using the metal oxide process saves up to $15,000/year in operation costs.
• Catalyst cost: The metal oxide process costs $260,000/year, while silver regeneration costs $20,000/year. Thus, the silver regeneration process costs $240,000 less per year
• Power consumption cost: metal oxide processes are higher than a silver catalyst process by about $440,000/year. (metal oxide process 70kwh/t, silver catalyst process 26kwh/t, electricity unit price $0.1/kwh)
• Using the metal oxide process saves about $740,000/year.
