The Dafne Plant is an innovative apparatus with dynamic molecular sieves. It finds its main field of application in the dehydration of gases and has been designed to obtain the dew point of the gases according to standard specifications (for example: - 5 ° C @ 72 Bar): the gas therefore comes to be in the ideal conditions of use and transport while avoiding the formation of unwanted hydrates.
The process uses dynamic molecular sieves (transported fluid bed), of completely innovative engineering. The regeneration phase is carried out with very small quantities of the same preheated gas: no foreign gas molecules are introduced.
The plant has a very competitive construction cost, compared with a so-called traditional plant and completely negligible dimensions.
Adopting it also reduces the entire "blow-down" system and therefore not only constitutes a significant technological leap forward in the field of wellhead treatment but has a significant positive impact on the environment and on the reduction of greenhouse gas emissions as in case of need, the volumes of depressurized gas sent to the emergency torch are much lower. For example, just 33,500 kg / h compared to 134,000 kg / h of traditional glycol systems of equal capacity. This also constitutes a further strong source of savings as it makes it possible to install less high and expensive emergency torches and to reduce the spaces of respect. Lastly, with the use of the Dafne Plant, even near the base of the emergency torch, the thermal radiation produced never reaches dangerous levels for humans (irreversible lesions 5.0 kW / m2 or reversible lesions 3.0 kW / m2).
Dafne Plant is easily convertible into a chemical production plant, with the addition of some elements or with small variations: in this way it is possible to produce methanol or alkanes or other chemicals, while maintaining the main installation structure.
