二氧化碳回收工厂(CBU)是以各种燃料如柴油、重油、煤油、天然气通过燃烧、洗涤、吸收、解析、分离等工艺技术完成的。系统采用集中控制，确证系统安全、稳定，所有仪器、仪表都预装在壳块内，便于运输 、减少现场安装、调试时间。

  二氧化碳回收工厂产量：25-1000 kg/hr，其他产量另行设计。

  系统是基于MEA冷却吸收和加热解析原理，烟气首先通过碱液清洗冷却，去除二氧化硫，再通过烟气风机将烟气进入MEA吸收塔进行吸收，残余气体排放到大气，此时吸收塔MEA吸收二氧化碳变成富液通过贫富换热器进行能量回收，然后进入解析塔后解析出二氧化碳，解析塔内MEA释放二氧化碳后就成贫液，通过贫液泵进入贫富换热器进行能量回收，贫液冷却又回到吸收塔进行吸收，完成循环。

  从解析塔释放出的二氧化碳气体通过二氧化碳冷却器冷却，进入高锰酸钾塔进行净化，净化后的二氧化碳气体被二级二氧化碳压缩机压缩到16bar，进行脱水干燥到露点-60℃，再通过活性炭吸附异味，然后通过二氧化碳管式换热器冷却到-30℃，进行液化。

  匹配二氧化碳管式换热器液化冷冻机以R22为冷冻剂，自动控制二氧化碳液化温度。

  液态二氧化碳通过深冷液化进入绝热二氧化碳储罐储存。

CO2 Generating Plant (CBU) is based on combustion of various fossil fuels such as diesel oil, heavy oil, kerosene or natural gas. Through appropriate combustion, scrubbing, absorbing, stripping and separation technology.The plants are supplied with a control panel, which ensures continuous trouble-free operation. All instruments installed on the skids are wired to junction boxes prior to shipment and thus reducing installation and commissioning time on site.CO2 Generating Plant Standard Sizes: 25-1000 kg/hr-other sizes available on request.

The plant is based on combustion in the MEA heater unit. By means of washing with soda lye in a flue gas，Scrubber the flue gas is cooled and any sulphur dioxide is removed. From the flue gas scrubber, the flue gas is led through the absorber by means of an exhauster where the CO2 content of the flue gas is absorbed in a MEA (Monoethanolamine) solution. The gas residue is exhausted. The CO2 rich MEA solution is preheated in the rich/lean solution heat exchanger before it is pumped to the stripper where by further heating CO2 is released. The stripped lean MEA solution is led from the stripper through the rich/lean solution heat exchanger and the MEA cooler back to the absorber.

The CO2 gas is cooled in a gas cooler cleaned in a potassium permanganate(PPM) scrubber and led to theCO2 compressor, which compresses the gas in two stages to approx. 16 bar(g).To allow condensation the CO2 gas is dried in a dehydrator to a dew point of abt. -60℃. The CO2 is then passed through a carbon filter for removal of odors.The purified and dried gas is condensed in a multitube heat exchanger at a temperature of about-30℃.

The matching refrigeration plant is equipped with an freon compressor. The refrigeration plant maintains the correct operating pressure in the CO2 condenser.

The liquid deep-cooled CO2 is led to an insulated CO2 storage tank.
