Systems and methods for integrated glycerol carbonate and/or urea production are provided. This disclosure pertains to development of a process for production of glycerol carbonate and/or urea from ammonia, carbon dioxide and glycerol. The process integrates glycerol carbonate production into a urea production process. The urea produced in the production facility may be used to produce glycerol carbonate by reacting urea with glycerol. The ammonia generated by glycerol carbonate production may be recycled back to urea production. Unreacted urea from the glycerol carbonate production may be separated and recycled to the urea product stream. The systems and methods can reduce the cost for urea production and increase product value of the excessive glycerol produced from other chemical plants. 用于整合生产碳酸甘油酯和/或尿素的系统和方法。本公开涉及由氨、二氧化碳和甘油生产碳酸甘油酯和/或尿素的方法的开发。该方法将碳酸甘油酯生产整合到尿素生产过程中。在生产设备中生产的尿素可用于通过使尿素与甘油反应来生产碳酸甘油酯。由碳酸甘油酯生产而生成的氨可以再循环回尿素生产中。来自碳酸甘油酯生产的未反应的尿素可以被分离并再循环至尿素产物流。该系统和方法可以降低尿素生产的成本并增加从其他化工厂生产的过量甘油的产品价值。
