摘要： PURPOSE: Disclosed is a method for simultaneously modernizing the subjects plants by a technically easily method which adds a carbamic acid synthesis and decomposition section to the existing sections, to increase production capacity of each plant and reduce energy consumption at a low investment cost. CONSTITUTION: This method is to add a carbamic acid synthesis and decomposition section to the existing sections of an ammonia and urea production plant. The added sections include means for, e.g. supplying the compressed unrefined ammonia synthesis gas flow containing carbon dioxide, hydrogen and nitrogen to the carbamic acid synthesis section; supplying part of the flow from the ammonia synthesis section, containing ammonia, hydrogen and nitrogen, to the carbamic acid synthesis section; supplying at least part of the flow from the urea recovering section, containing carbamic acid in the aqueous solution, to the carbamic acid decomposition section, and supplying the flow from the decomposition section, containing ammonia vapor and carbon dioxide gas, to the urea synthesis section.
摘要翻译：目的：公开一种通过技术上容易的方法对现有植物进行现代化改造的方法，该方法向现有部分添加氨基甲酸合成和分解部分，以增加每个工厂的生产能力并以低投资成本降低能耗。规定：该方法是向氨和尿素生产装置的现有部分添加氨基甲酸合成和分解部分。添加的部分包括用于例如，将含有二氧化碳，氢气和氮气的压缩的未精炼氨合成气流供应到氨基甲酸合成段; 将来自氨合成部分的含有氨，氢和氮的部分流量供给到氨基甲酸合成部分; 将含有氨基甲酸的尿素回收部的至少一部分流量供给到氨基甲酸分解部，并将含有氨蒸汽和二氧化碳气体的分解部的流体供给到尿素合成部。
