Latest Patents
Doerr holds a patent for a "Continuous process for the recovery of caprolactam." This innovative process allows for the continuous recovery of caprolactam from solid polycaprolactam waste through depolymerization or from liquid polycaprolactam extraction water. The process generates a caprolactam water vapor mixture, which is then upgraded in a distillation zone. A minor portion of this mixture is condensed and recycled, while the major portion is compressed, mixed with fresh steam, and passed to either the extraction zone or depolymerization reaction.
