用于通过反升华以升高的压力提取二氧化碳的方法和系统
摘要：
一种通过反升华从气流中去除CO2的方法，包括以下步骤：a)将包含CO2的气流引入结霜容器；b)将所述结霜容器中的该气流的至少一部分的温度降低到固体CO2通过反升华而沉积的温度；c)从结霜容器中排放减少了CO2的气流；以及d)回收沉积的固体CO2；其中步骤b)中的气流的压力高于大气压力。一种用于从气流中去除CO2的反升华系统，包括：构造成以便接收气流的结霜容器(101)，所述结霜容器包括低温制冷装置(107)，其构造成用于将所述结霜容器中的气流的至少一部分的温度降低到固体CO2通过反升华而沉积所处的温度；以及压缩机(108)，其构造成以便提高供给到结霜容器的气流的气压。
摘要（英）：

A method for removal of CO2 from a gas stream by anti-sublimation comprises the steps of: a) introducing a gas stream containing CO2 into a frosting vessel; b) reducing the temperature of at least a portion of the gas stream in said frosting vessel to a temperature at which solid CO2 is deposited by anti-sublimation; and c) discharging the gas stream depleted of CO2 from the frosting vessel; and d) recovering the deposited solid CO2; wherein the pressure of the gas stream in step b) is higher than atmospheric pressure. An anti-sublimation system for removal of CO2 from a gas stream, comprising: a frosting vessel (101) configured to receive the gas stream, said frosting vessel comprising a low temperature refrigeration device (107) configured for reducing the temperature of at least a portion of a gas stream in said frosting vessel to a temperature at which solid CO2 is deposited by anti-sublimation; and a compressor (108) configured to increase the gas pressure of the gas stream which is fed to the frosting vessel.
