发明名称 PROCESS FOR RECOVERING BY-PRODUCT GASES AT HIGH PRESSURE IN MELAMINE PRODUCTION
摘要 In the process of producing melamine by the thermal decomposition of urea or its derivatives, an improved method for separating the molten material (composed mainly of melamine formed in a pressurized reactor) from the gases (composed mainly of ammonia and carbon dioxide) under nearly the same conditions as prevail in said reactor, and for recovering the by-product gases as pressurized by-product gases, with the crude liquid melamine eliminated therefrom.
