Innovative Process Solutions
The LIST KneaderReactor technology is being effectively employed for a wide variety of chemical reactions under stoichiometric or nearly stoichiometric conditions. It enables the reaction in the pasty and/or solid phase which has the advantage that the reactants have a much more intensive contact accelerating the perfect reaction.
Reactions, where the product undergoes a phase change from a pasty to a solid state or excessive volumes of foam are generated, can be easily handled in LIST Kneader Reactor. For diffusion limited or heat transfer controlled reactions the residence time of the product is freely adjustable.
The LIST technology, which has virtually almost no limitation regarding the product viscosity, helps to avoid the use of solvents or stripping agents which would require an additional complex and costly separation process downstream of the reactor.
LIST has developed a continuous reaction process for the combined synthesis and vacuum drying of HMM. This reaction is nearly stoichiometric, so much less formaldehyde needs to be handled and recovered.
Most importantly, the final product discharged from the drying stage is a free-flowing powder that is easy to handle and contains very low levels of formaldehyde and water.
