    Abstract: 本发明涉及制备尿素的方法和设备,尤其是在尿素反应器中在约125巴至约350巴的压力下在尿素合成溶液中由从二氧化碳和氨制备的氨基甲酸铵得到尿素。反应器带有一个水平放置的冷凝区域,并含有一个热交换器。根据本发明的方法,将NH3和CO2输入反应器中,并大部分吸收在尿素合成溶液中。在冷凝过程中形成的大部分热量通过热交换器排出。在反应器中尿素合成溶液的停留时间优选这样选择从而制备至少约85%的理论上可得到量的尿素。随后,尿素合成溶液可加工成尿素溶液或固体尿素。

    Abstract: A method of producing a low-molecular luminous material dispersant having: inserting a coat agent in gas phase and an inner gas into a vacuum atmosphere, wherein the coat agent has a strong affinity for a solvent when the coat agent is in liquid phase; heating and vaporizing a low-molecular luminous material in the vacuum atmosphere so as to obtain a mix gas comprising the low-molecular luminous material and inner gas; cooling the mix gas so as to obtain a coat agent in liquid phase; and recovering the coat agent in liquid phase and adding the coat agent in liquid phase into the solvent so as to obtain the low-molecular luminous material dispersant.
