簡介
CMM-6RL
以吸附劑為基礎的低粘度船舶燃料淨化是可在GlobeCore的CMM-6RL裝置中實現的。該裝置由6個填充有天然吸附劑的再生圓柱所組成。
燃料被輸送泵送通過這些再生圓柱中,吸附劑捕捉有害的雜質,並由於其有效的吸附能力而將其保留在其顆粒中。在該裝置的出口處,我們得到澄清的低粘度船舶燃料,其硫含量降低,完全可以用於船用柴油發動機廠,並符合現行的環境法規。
燃油費用佔航行中的大部分運營成本。低粘度船舶燃料最常被用於中、高速柴油機廠。它類似於汽車柴油燃料,但也有一些區別:
到目前為止,低粘度船舶燃料的使用沒有面臨任何限制;然而,近年來緊收的環境保護法迫使河川和海洋船隊改用低硫含量的燃料。這種燃料的價格非常高,為了節省開支,使用便宜的船舶燃料,需要首先通過減少環境中不需要的雜質(包括硫)的含量來生產製造。
低粘度船舶燃料的生產方法
過濾、重力誘導和離心淨化被用於低粘度船用燃料的初步製程方。這些方法更側重於去除燃料中的機械雜質和水,但對對環境更有害的雜質的含量消除影響不大。為了解決這一任務,最好使用吸附劑對低粘度船用燃料進行淨化和澄清。
在CMM-6RL裝置中進行低粘度船舶燃料再生
以吸附劑為基礎的低粘度船舶燃料淨化是可在GlobeCore的CMM-6RL裝置中實現的。該裝置由6個填充有天然吸附劑的再生圓柱所組成。
燃料被輸送泵送通過這些再生圓柱中,吸附劑捕捉有害的雜質,並由於其有效的吸附能力而將其保留在其顆粒中。在該裝置的出口處,我們得到澄清的低粘度船舶燃料,其硫含量降低,完全可以用於船用柴油發動機廠,並符合現行的環境法規。
CMM-6RL裝置的操作特點
吸附法淨化燃料油的缺點包括需要儲存和處理使用過的吸附劑。 GlobeCore設備不存在這個問題,因為吸附劑的特性是通過燃燒來回收的,不重再生圓柱中取出吸附劑的情況下進行重新活化。在重新活化和冷卻之後,吸附劑可以重新用於低粘度船舶燃料的淨化和澄清。

Fuel expenses account for the majority of operating costs in navigation. Low-viscosity marine fuel is most often used in medium- and high-speed diesel engine plants. It resembles automotive diesel fuel, but has some differences:
Thus far, the use of low-viscosity marine fuel has faced no restrictions; however, tightened environmental laws compel river and marine fleets to switch to fuels with a low sulfur content. The price of such fuels is very high and in order to save money, cheaper marine fuels are used and require to be first prepared by reducing the content of environmentally unwanted impurities, including sulfur.
Methods for preparation of low-viscosity marine fuel
Filtration, gravity-induced and centrifugal purification are used in preliminary preparation of low-viscosity marine fuel. These methods are focused rather on removal of mechanical impurities and water from the fuel, but have little effect on the content of impurities that are more harmful to the environment.
In order to address this task, it is advisable to use purification and clarification of low-viscosity marine fuel by means of adsorbents.
Low-viscosity marine fuel polishing in CMM-6RL unit
Adsorbent-based low-viscosity marine fuels polishing are implemented in CMM-6RL unit from GlobeCore. This unit consists of 6 columns filled with natural adsorbent.
The fuel is pumped through the columns, and the adsorbent captures harmful impurities and retains them in its granules due to its well-developed absorptive abilities. At the outlet of the unit, we obtain clarified low-viscosity marine fuel with a reduced sulfur content which will be completely ready for use in marine diesel engine plants and which is compliant with environmental law regulations.
Operation features of CMM-6RL unit
The disadvantages of the adsorptive method for purification of oils and fuels include the need to stockpile and dispose of the used adsorbent. GlobeCore equipment does not have this problem, because the properties of the adsorbent are reclaimed by burning it without removing from the columns. After reactivation and cooling, the adsorbent can be reused for purification and clarification of low-viscosity marine fuel.
Duration of operating cycles and power consumption
CMM-6RL unit for purification and clarification of low-viscosity marine fuels sequentially operates in the following modes:
