Description
本發明係關於一種超臨界萃取的進料方法;特別關於一種在依靠液態萃取劑源與萃取槽之間的壓力差及液位差將液態萃取劑灌入萃取槽中的超臨界萃取的進料方法。 The invention relates to a feeding method for supercritical extraction; in particular, it relates to a feeding method for supercritical extraction that relies on the pressure difference and liquid level difference between the liquid extraction agent source and the extraction tank to pour the liquid extraction agent into the extraction tank. method.
超臨界萃取技術的應用範圍很廣,舉如:萃取香草植物中的精油、胺基酸、咖啡鹹、白米脫脂、蠶絲脫膠、清洗、去污等等。 Supercritical extraction technology has a wide range of applications, such as: extracting essential oils from vanilla plants, amino acids, coffee salt, white rice defatting, silk degumming, cleaning, decontamination, etc.
在習用的超臨界萃取方法中,為了確保萃取槽內具有足夠的壓力,大多以加壓泵將液態萃取劑打入萃取槽內或用壓縮機將氣態萃取劑加壓冷卻液化後再加熱為超臨界萃取劑進入萃取槽內。但是以加壓泵將液態萃取劑打入萃取槽內的方式,或以壓縮冷卻液化萃取劑的方法,不但會增加設備成本,而且會增加操作步驟,造成許多困擾。 In the conventional supercritical extraction method, in order to ensure sufficient pressure in the extraction tank, a pressurized pump is mostly used to drive the liquid extractant into the extraction tank or a compressor is used to pressurize, cool, and liquefy the gaseous extractant and then heat it into a supercritical extraction tank. The critical extractant enters the extraction tank. However, using a pressurized pump to drive the liquid extractant into the extraction tank, or compressing and cooling the liquefied extractant, will not only increase the equipment cost, but also increase the operating steps, causing a lot of trouble.
基本上,習用的超臨界萃取方法約可分為靜態萃取法和動態萃取法二種。 Basically, commonly used supercritical extraction methods can be roughly divided into two types: static extraction methods and dynamic extraction methods.
習用靜態萃取法是先將原料放入萃取槽後封蓋,再將液態萃取劑用加壓泵打入萃取槽內,之後再將液態萃取劑加熱成為超臨界態萃取劑,並靜置一段時間進行 萃取步驟,產生萃取液及萃餘物殘渣,之後將萃取液排出經氣化分離法,使氣態萃取劑發散,並取得萃取物。 The conventional static extraction method is to first put the raw materials into the extraction tank and then seal the lid, then pump the liquid extractant into the extraction tank with a pressurized pump, and then heat the liquid extractant to become a supercritical extraction agent and let it stand for a period of time. conduct In the extraction step, an extraction liquid and an extraction residue are produced, and then the extraction liquid is discharged through a gasification separation method to disperse the gaseous extractant and obtain the extract.
但是,習用靜態萃取法大都是將萃取液中的萃取劑氣化後排放到大氣中,很浪費萃取劑,否則就需要用壓縮機將氣態萃取劑壓縮冷凝為液體後才能儲藏備用。 However, the conventional static extraction method mostly vaporizes the extractant in the extraction liquid and discharges it into the atmosphere, which is a waste of extractant. Otherwise, a compressor needs to be used to compress and condense the gaseous extractant into a liquid before it can be stored for later use.
習用動態萃取法是先將原料放入萃取槽後封蓋,再將氣態萃取劑用壓縮機壓縮後打入冷凝器冷凝為液態萃取劑,之後再將液態萃取劑加熱為超臨界態萃取劑,隨即使超臨界態萃取劑流入萃取槽內進行萃取步驟,產生萃取液及萃餘物殘渣,最後將萃取液排入氣化分離塔,將萃取劑氣化為氣態萃取劑與液態萃取物分離而取得萃取物,並將氣態萃取劑經壓縮機壓縮之後,再經冷凝器冷凝為液態萃取劑,再加熱超臨界化,如上繼續循環萃取作業。習用動態萃取法的萃取效率比習用靜態萃取法高,但需要壓縮機及冷凝器等設備,設備費高,操作較為複雜,且有耗費電力及機械耗損等問題。 The conventional dynamic extraction method is to first put the raw materials into the extraction tank and then seal it, then compress the gaseous extractant with a compressor and put it into a condenser to condense it into a liquid extractant, and then heat the liquid extractant into a supercritical state extraction agent. Then the supercritical extraction agent flows into the extraction tank for the extraction step, producing an extraction liquid and an extraction residue. Finally, the extraction liquid is discharged into the gasification separation tower, and the extraction agent is vaporized into a gaseous extraction agent and the liquid extract is separated. The extract is obtained, and the gaseous extractant is compressed by a compressor, and then condensed into a liquid extractant through a condenser, and then heated to become supercritical, and the extraction cycle continues as above. The extraction efficiency of the conventional dynamic extraction method is higher than that of the conventional static extraction method, but it requires equipment such as compressors and condensers. The equipment cost is high, the operation is complicated, and there are problems such as power consumption and mechanical loss.
發明人有鑑於此,積極研究,發現依靠液態萃取劑源與萃取槽之間的壓力差及液位差,或以控制溫度造成萃取劑源與萃取槽間的壓力差,就可以依照所需要液態萃取劑輸送萃取槽內,進而改善習用的超臨界萃取方法的缺點,終於發展出本發明。 In view of this, the inventor actively researched and found that relying on the pressure difference and liquid level difference between the liquid extraction agent source and the extraction tank, or controlling the temperature to cause a pressure difference between the extraction agent source and the extraction tank, the liquid can be produced according to the required The extraction agent is transported into the extraction tank, thereby improving the shortcomings of the conventional supercritical extraction method, and finally the present invention was developed.

Examples thereof will be described in detail below.
圖2為配合超臨界萃取的進料方法的超臨界萃取的進料裝置100。超臨界萃取的進料裝置100的基本結構包括有一液態萃取劑源1、一萃取槽2及一萃取液槽3。例如液態萃取劑源1與萃取槽2等各結構之間可設有控制閥或手動閥(圖中未示)以控制兩者是否相連通。
Figure 2 shows a supercritical
步驟a)為準備步驟,準備一液態萃取劑源1、一原料101、一萃取槽2及一萃取液槽3。液態萃取劑源1中存放液態萃取劑11(在圖2~3中,為了方便示意,各元件之間連接的管線僅以一線條表示,且指向液態萃取劑源1、1a、萃取槽2、2a的11、11a、22、22a等元件編號係指在存放在其中的萃取劑、萃取液),液態萃取劑源1連接萃取槽2,並設有一第一開關(圖中未示),第一開關可控制液態萃取劑源是否連通萃取槽。萃取劑11為各種可超臨界化的物質,例如二氧化碳等。在本發明中,萃取劑11在不同的進程中可能為液體、超臨界流體或氣體,為敘述操作步驟方便,故分別稱為液態萃取劑、超臨界態萃取劑或氣態萃取劑。液態萃取劑源1可以是一存有液態萃取劑的鋼瓶或鋼槽,或是回收液態萃取劑的結構,或其他可以提供儲存液態萃取劑的結構。液態萃取劑源1內具有預定壓力及預定溫度,通常為常溫及其飽和蒸汽壓;依據設定的萃取操作條件的估算將預定量的液態萃取劑灌入該萃取槽中。萃取槽2上設有加熱及冷卻機構(圖中未示)及溫度控制器
(TIC,Temperature Indicator Controller)21,溫度控制器21可以控制加熱及冷卻機構對萃取槽2加熱及冷卻,進而達到萃取劑超臨界化或方便液態萃取劑從萃取劑源灌入萃取槽。如圖2所示,原料101為被萃取物。
Step a) is a preparation step, preparing a liquid
茲舉例說明使液態萃取劑源1與萃取槽2之間形成壓力差及/或液位差的技術手段:1.通常在常溫下萃取劑源1內的壓力為萃取劑的飽和蒸汽壓,而空萃取槽內為常壓,因此兩槽之間產生壓差。2.形成該壓力差的方法很多,例如在步驟b)之後,透過冷卻機構降低萃取槽內的溫度也可以降低萃取槽的壓力,使兩槽之間形成壓力差,進而使萃取劑源的液態萃取劑繼續灌入萃取槽中。3.將萃取劑源置於相對高於萃取槽的位置,使該液態萃取劑源與該萃取槽之間形成液位差,以便使萃取劑源的液態萃取劑能夠灌入萃取槽中。另外,液態萃取劑源1須倒立或將一液態萃取劑取出管線(圖中未示)深入該萃取劑源底部以利輸出該液態萃取劑。
Here is an example to illustrate the technical means of forming a pressure difference and/or a liquid level difference between the liquid
步驟b)為填料步驟,將該原料101放入該萃取槽中並封蓋。
Step b) is the filling step. Put the
步驟c)為填充萃取劑步驟,將該液態萃取劑源的定量液態萃取劑灌入該萃取槽中;該液態萃取劑源內具有預定壓力及預定溫度;依靠該液態萃取劑源與該萃取槽之間的壓力差及液位差將該液態萃取劑灌入該萃取槽中。在此步驟是將定量的液態萃取劑灌入萃取槽中,萃取劑之定量可依所需的萃取溫度及壓力而調整,例如在將液 態萃取劑灌入萃取槽時,萃取槽內的壓力會快速的上升至一第一壓力範圍,該壓力即為在該溫度下該液態萃取劑的飽和蒸汽壓。 Step c) is the step of filling the extraction agent, pouring a quantitative amount of the liquid extraction agent from the liquid extraction agent source into the extraction tank; the liquid extraction agent source has a predetermined pressure and a predetermined temperature; relying on the liquid extraction agent source and the extraction tank The pressure difference and liquid level difference between them pour the liquid extraction agent into the extraction tank. In this step, a quantitative amount of liquid extraction agent is poured into the extraction tank. The quantitative amount of the extraction agent can be adjusted according to the required extraction temperature and pressure. For example, when adding liquid When the liquid extractant is poured into the extraction tank, the pressure in the extraction tank will quickly rise to a first pressure range, and this pressure is the saturated vapor pressure of the liquid extractant at that temperature.
步驟d)為萃取步驟,將該萃取槽內的溫度提升至一第一溫度範圍,藉以使該液態萃取劑成為超臨界態萃取劑,以進行萃取程序。第一溫度範圍為超過萃取劑的臨界溫度。此外,在加熱提高萃取槽內的溫度的過程中,還會提高萃取槽內的壓力,使萃取槽內的壓力達到萃取劑的臨界壓力以上,以使液態萃取劑變為超臨界態萃取劑。在液態萃取劑轉變為超臨界態萃取劑後,其密度和黏度將隨之降低,使超臨界態萃取劑容易滲入原料中進行萃取工作。此外,提高萃取槽內的溫度,不但會使萃取槽內的液態萃取劑氣化而提高壓力,還可因壓力提高而使萃取劑更容易滲入原料中進行萃取工作。 Step d) is an extraction step, in which the temperature in the extraction tank is raised to a first temperature range, so that the liquid extraction agent becomes a supercritical extraction agent to perform the extraction process. The first temperature range is above the critical temperature of the extraction agent. In addition, during the process of heating to increase the temperature in the extraction tank, the pressure in the extraction tank will also be increased, causing the pressure in the extraction tank to reach above the critical pressure of the extraction agent, so that the liquid extraction agent becomes a supercritical extraction agent. After the liquid extraction agent is transformed into a supercritical extraction agent, its density and viscosity will decrease accordingly, making it easier for the supercritical extraction agent to penetrate into the raw material for extraction. In addition, increasing the temperature in the extraction tank will not only vaporize the liquid extraction agent in the extraction tank and increase the pressure, but also make it easier for the extraction agent to penetrate into the raw materials for extraction due to the increase in pressure.
步驟e)為萃取物帶出步驟,將該萃取槽內的溫度降低至一第二溫度範圍,藉以使該超臨界態萃取劑成為液態萃取劑,並藉以將萃取液從原料內帶出。第二溫度範圍低於萃取劑的超臨界溫度。藉由冷卻降低萃取槽內的溫度及壓力,使超臨界態萃取劑變為液態萃取劑,藉以將萃取液22從原料內帶出。
Step e) is the step of taking out the extract. The temperature in the extraction tank is lowered to a second temperature range, so that the supercritical extraction agent becomes a liquid extraction agent, and the extraction liquid is taken out from the raw material. The second temperature range is below the supercritical temperature of the extraction agent. The temperature and pressure in the extraction tank are reduced by cooling, so that the supercritical extraction agent becomes a liquid extraction agent, thereby bringing the
步驟f)為萃取液排出步驟,將萃取液22排到萃取液槽。
Step f) is the extraction liquid discharge step, and the
步驟g)為萃取液分離步驟,將萃取液分離為萃取劑及萃取物。將萃取液分離為萃取劑及萃取物的分離手
段4有很多方法,可方便將萃取液分離為萃取劑11及萃取物103。
Step g) is an extraction liquid separation step, which separates the extraction liquid into an extraction agent and an extract. A separation process that separates the extract into extractant and extract
There are many methods in
步驟h)為萃餘物殘渣清除步驟,從該萃取槽中取出萃餘物殘渣。 Step h) is the step of removing the raffinate residue, which is to take out the raffinate residue from the extraction tank.
藉由上述的超臨界萃取的進料方法,本發明可以依靠液態萃取劑源與萃取槽之間的壓力差及液位差將液態萃取劑灌入萃取槽,與習用的採用加壓泵灌入萃取劑的萃取方法相較下,不需要利用例如壓縮機等設備就能夠達到超臨界萃取的目的,因此可以節省成本。 Through the above-mentioned supercritical extraction feeding method, the present invention can rely on the pressure difference and liquid level difference between the liquid extraction agent source and the extraction tank to pour the liquid extraction agent into the extraction tank, unlike the conventional use of a pressurized pump to pour the liquid extraction agent into the extraction tank. Compared with the extraction method of extraction agent, supercritical extraction can be achieved without using equipment such as a compressor, so it can save costs.
