Conversion Process Of Anhydrous Off-Gas Stream Coming From Melamine Synthesis Plants Into Urea
Patent No. EP3814320 (titled "Conversion Process Of Anhydrous Off-Gas Stream Coming From Melamine Synthesis Plants Into Urea") was filed by Eurotecnica Melamine on Jun 28, 2019. The application was issued on Dec 6, 2023.
Patent Summary
A process for converting anhydrous off-gases from melamine synthesis into urea, eliminating the need for separate urea plants. The process involves isobaric cooling, transformation into ammonium carbamate, isothermal pressurization, and isobaric heating to produce urea. The process can be integrated into the melamine plant, enabling direct recycling of the produced urea back to the melamine synthesis reactor.
