酿酒厂CO₂回收设备

  酒精CO2回收设备(RBU)是酿酒发酵通过若干化学过程富集的CO2。

  CO2回收设备通过适当清洗、洗涤，过滤与分离技术达到高质量的CO2。

  CO2生产设备配有控制面板，确保无故障运行。所有的仪器仪表安装在壳块内，便于运输，减少现场安装、调试时间。

  酿酒CO2生产设备生产能力：145公斤/小时，285公斤/小时，500公斤/小时，1000公斤/小时——其它生产能力根据要求另行提供。

  在酒精发酵过程释放的CO2气体中含有大量的杂质，首先通过除沫器进行清除泡沫，除沫器之后是三道洗涤器。

  原料气经过洗涤器后CO2气体中的酒精和气溶胶被去除，水被输送到除沫器循环利用。CO2气体通过高锰酸钾洗涤器去除NOx，紧接着又一次洗涤，余下的杂质通过水去除。

  CO2气体通过两级无油CO2压缩机配有进/出冷却器被压缩到约16bar。CO2压缩机通过气囊体积控制。

  被压缩的CO2气体通过双联活性炭过滤器去除异味和挥发性化合物成分。活性炭过滤器是由蒸汽或热空气再生。两个过滤器并联保证无间断运行过程中再生。

  将压缩后的CO2气体在干燥器内干燥到露点-60℃，干燥器通过从CO2冷凝器来的惰性气体也就是相当于不凝结气体冲净系统通过电加热自动再生。

  被净化的和干燥的CO2气体通过列管换热器在温度-30℃下进行液化。同时配套氨冷或氟油润滑压缩机组。保持CO2冷凝器正确的操作压力。
  液态深冷CO2被送到CO2储罐。

CO2 Recovery Plants (RBU) are based on recovery from alcohol distillery.CO2 can be recovered from distillery fermenting processes as well as from a number of  chemical processes with emission of CO2-rich gases.

Through appropriate washing, scrubbing, filtration and separation technology the CO2 Recovery Plants for distillery process meet the strictest CO2 quality requirements.

The plant is supplied with a control panel which ensures continuous trouble free operation of the plant. All instruments installed on the skids are wired to junction boxes prior to shipment and thus reducing installa-tion and commissioning time on site.

CO2 Recovery Plant for Distillery Process Standard Sizes:
145 kg/hr, 285 kg/hr, 500 kg/hr and 1000 kg/hr other sizes available on requesment

The CO2 gas developed in the distillery fermentation process contains a lot of impurities. First step is to let the CO2 pass a foam trap where it is cleaned for foam. The foam trap is followed by 3 scrubbers.

Raw gas scrubber where the CO2 gas is cleaned for alcohols and aerosoles by means of water, which is reused in the foam trap. The CO2 steams into a permanganate scrubber for removal of NOx, followed by an after scrubber, where the remaining main impurities are removed by means of water.

The CO2 gas is compressed to approx. 16 bar by means of a two-stage oil-free CO2 compressor which is equipped with inter- and after coolers. The engaged capacity of the CO2 compressor is controlled according to the filling of the CO2 accumulation balloon.

The compressed CO2 gas is filtered in a double activated carbon filter which removes odors and volatile compounds. The activated carbon filters are regenerated by means of steam or hot air. A parallel connection of two filters enables an interruption free operation of the plant during regeneration.

To allow condensation the CO2 gas is dried in a dehydrator to a dew point of abt. -60℃.The dehydrator is electrically heated and automatically regenerated by inert gas from the CO2 condenser and thereby acts as a purging system for non-condensable gases.

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 ammonia or freon oil lubricated 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.
