酒精CO2回收設備(RBU)是釀酒發(fā)酵通過若干化學過程富集的CO2。

  CO2回收設備通過適當清洗、洗滌，過濾與分離技術達到高質(zhì)量的CO2。

  CO2生產(chǎn)設備配有控制面板，確保無故障運行。所有的儀器儀表安裝在殼塊內(nèi)，便于運輸，減少現(xiàn)場安裝、調(diào)試時間。

  釀酒CO2生產(chǎn)設備生產(chǎn)能力：145公斤/小時，285公斤/小時，500公斤/小時，1000公斤/小時——其它生產(chǎn)能力根據(jù)要求另行提供。

  在酒精發(fā)酵過程釋放的CO2氣體中含有大量的雜質(zhì)，首先通過除沫器進行清除泡沫，除沫器之后是三道洗滌器。

  原料氣經(jīng)過洗滌器后CO2氣體中的酒精和氣溶膠被去除，水被輸送到除沫器循環(huán)利用。CO2氣體通過高錳酸鉀洗滌器去除NOx，緊接著又一次洗滌，余下的雜質(zhì)通過水去除。

  CO2氣體通過兩級無油CO2壓縮機配有進/出冷卻器被壓縮到約16bar。CO2壓縮機通過氣囊體積控制。

  被壓縮的CO2氣體通過雙聯(lián)活性炭過濾器去除異味和揮發(fā)性化合物成分。活性炭過濾器是由蒸汽或熱空氣再生。兩個過濾器并聯(lián)保證無間斷運行過程中再生。

  將壓縮后的CO2氣體在干燥器內(nèi)干燥到露點-60℃，干燥器通過從CO2冷凝器來的惰性氣體也就是相當于不凝結氣體沖凈系統(tǒng)通過電加熱自動再生。

  被凈化的和干燥的CO2氣體通過列管換熱器在溫度-30℃下進行液化。同時配套氨冷或氟油潤滑壓縮機組。保持CO2冷凝器正確的操作壓力。
  液態(tài)深冷CO2被送到CO2儲罐。

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.
