We prioritize safety in every aspect of our plant design and operation, ensuring the highest standards are met to protect both personnel and the environment. Therefore, the fasil® process has a high degree of inherent safety.

Safety

Key benefits demonstrating the high degree of inherent safety of the fasil® process are:

  • No hot oil is used, only water/steam is used as cooling media which mitigates fire risks
  • No oxygen is present in the absorber, as all oxygen is consumed in the reactions
  • The fasil® process operates above the upper flammable limit, giving a wide range of safe operation

Operating points

Power failure

The fasil® process operates in the fuel rich region, giving it a wide range of safe operation. The metal oxide process operates in the narrow fuel lean region.
In the event of a power failure, the supply of process air is lost. Without intervention, the fasil® process moves in a safe direction away from the flammable region. The metal oxide process requires intervention to prevent entering the flammable region.
Safety is therefore in favour of the fasil® process.

Technology

Two competing technologies

Dynea has a long history with formaldehyde production. The history starts in Norway in 1947, when the first fasil® plant using a crystalline silver catalyst was established. As the company growed, so did the number of formaldehyde plants. Alongside this growth, the technology was continuously developed further. Some major improvements were accomplished in the end of the 90's.
In pursuit of having the best available formaldehyde process technology, in 1987 Dynea purchased formaldehyde technology utilizing the metal-oxide catalyst from Reichold USA. Dynea further developed the technology in the early 90's, and multiple plants based on the metal-oxide technology were established.

Having formaldehyde plants based on two different process technologies in operation, the question arose which technology was the best technology for future plants. In the year 2000, Dynea did a detailed operational analysis to select the superior technology, focusing of safety and OPEX.
The fasil® process based on crystalline silver catalyst won this comparison, having a high level of inherent safety and the lowest total operational cost. Dynea has ever since exclusively used fasil® technology for new plants.
