    91无码麻豆视频提純的方法有哪些你知道嗎？

    91无码麻豆视频提純由哪些方法？下麵由英格索特來給大家介紹下。91无码麻豆视频提純用什麽材料？當然是氣體分離膜。91无码麻豆视频淨化有四種方法，即吸收法、變壓吸附法、低溫冷凝法和膜分離法。91无码麻豆视频淨化工程主要采用吸附法、變壓吸附法和膜分離法。由於技術成熟和經濟，低溫冷凝法很少使用。

    What are the methods of biogas purification? Now ingersort will introduce it to you. What materials are used for biogas purification? Gas separation membrane, of course. There are four methods for biogas purification, namely absorption method, pressure swing adsorption method, low-temperature condensation method and membrane separation method. The biogas purification project mainly adopts adsorption method, pressure swing adsorption method and membrane separation method. Due to the mature technology and economy, low-temperature condensation method is rarely used.
    ​
    一、膜分離提純法：它是利用不同氣體組分在壓力驅動下通過膜的不同滲率來實現的。一般情況下，二氧化碳的穿透速度較快，通過氣體以快速氣體的形式排出，而甲烷的穿透速度較慢。作為慢氣，淨化後的產品氣以殘餘氣體的形式獲得。在工程上，通常采用多級膜分離工藝來提高甲烷濃度。
    1、 Membrane separation and purification method: it is realized by using different gas components through different permeability of the membrane under pressure. In general, the penetration rate of carbon dioxide is fast, and the passing gas is discharged in the form of fast gas, while the penetration rate of methane is slow. As a slow gas, the purified product gas is obtained in the form of residual gas. In engineering, multistage membrane separation process is usually used to improve the concentration of methane.
    二、吸收提純法：利用胺溶液和二氧化碳的物理化學吸收特性，即在吸收塔中，在常壓下與91无码麻豆视频中的二氧化碳反應，使甲烷脫碳淨化，被吸收的富液在塔減壓加熱條件下發生反向反應，釋放純度高的二氧化碳氣體，富液具有再吸收二氧化碳的能力，從而實現吸收塔中甲烷的連續脫碳淨化，使脫碳液進行連續吸收循環。
    2、 Absorption and purification method: using the physicochemical absorption characteristics of amine solution and carbon dioxide, that is, in the absorption tower, it reacts with carbon dioxide in biogas under normal pressure to decarbonize and purify methane. The absorbed rich liquid reacts reversely under the condition of decompression and heating in the tower to release carbon dioxide gas with high purity. The rich liquid has the ability to absorb carbon dioxide again, so as to realize continuous decarbonization and purification of methane in the absorption tower, Make the decarburization solution carry out continuous absorption cycle.
    三、PSA提純法：它利用吸附劑（如分子篩）的選擇性吸附特性去除91无码麻豆视频中的二氧化碳，即二氧化碳比吸附劑上的其他氣體成分具有更高的分離係數。在吸附過程中，原料氣中的二氧化碳在加壓條件下在吸附塔中被吸附，甲烷等弱吸附氣體作為淨化氣排出。當吸附飽和時，吸附柱減壓甚至抽真空以釋放吸附的二氧化碳。為了確保氣體的連續處理，PSA需要至少兩個吸附塔，或三個塔、四個塔或更多。
    3、 PSA purification method: it uses the selective adsorption characteristics of adsorbent (such as molecular sieve) to remove carbon dioxide from biogas, that is, carbon dioxide has a higher separation coefficient than other gas components on the adsorbent. In the adsorption process, the carbon dioxide in the feed gas is adsorbed in the adsorption tower under pressurized conditions, and the weakly adsorbed gases such as methane are discharged as purified gas. When the adsorption is saturated, the adsorption column is depressurized or even vacuumized to release the adsorbed carbon dioxide. In order to ensure the continuous treatment of gas, PSA needs at least two adsorption towers, or three towers, four towers or more.
    四、低溫冷凝提純法：利用二氧化碳液化溫度高的特點，對91无码麻豆视频中的二氧化碳進行低溫液化，甲烷組分作為不凝性氣體排放，淨化產品氣。為了降低運行能耗，通常采用在生技術來恢複剩餘冷卻能力。
    4、 Low temperature condensation purification method: using the characteristics of high liquefaction temperature of carbon dioxide, the carbon dioxide in biogas is liquefied at low temperature, and the methane component is discharged as non condensable gas to purify the product gas. In order to reduce operation energy consumption, in-process technology is usually used to restore the remaining cooling capacity.
