柴油燃料淨化裝置

柴油被用於許多行業。其消費者包括船舶、曳引機、收割機、卡車、柴油火車等。許多企業試圖購買大批量的柴油，以保證自己免受季節性價格波動的影響，並通過使用石油產品的倉庫庫存來避免過度支付。
在長期儲存過程中，並非所有類型的柴油燃料都具有所需的穩定性。柴油會發生氧化、進水和形成樹脂物質。因此，柴油燃料會變黑並失去其操作性能。然，這樣的燃料是不能使用的，因為它將損害發動機的壽命，因為在發動機燃料供應裝置中會有樹脂沉積物，以及燃燒室、排氣閥和噴嘴壁上的煙塵結塊，水會使高壓燃料泵無法工作。因此，這種柴油燃料在注入柴油機和發電裝置之前應進行淨化與再生。

柴油燃料的淨化

長期儲存後的柴油有多種方法可以淨化：沉澱、過濾、離心。這些方法適合去除機械雜質和水；但是，它們不能恢復燃料的原始顏色和氣味，也不能降低硫含量。這時需要使用天然來源的特殊吸附劑進行額外淨化。

CMM-6RL裝置中的柴油燃料的再生

在CMM-6RL裝置中實施了吸附式柴油燃料淨化技術。該裝置由六個再生圓柱組成，每個圓柱都充滿了具有良好吸收性的吸附劑。當通過這些柱子時，吸附劑從燃料中捕獲不飽和和芳香烴、瀝青樹脂物質、硫、氮和含酸化合物。柴油被澄清，重新獲得其化學結構和操作性能。
吸附劑飽和後，СMM-6RL裝置切換到重新活化模式。在這種模式下，吸附劑的性能得到恢復，之後吸附劑被重新用於柴油燃料的淨化。

柴油燃料再生的CMM-6RL裝置操作特點

CMM-6RL裝置的主要特點是可以在不重再生圓柱中取出吸附劑的情況下進行重新活化。如果使用過的吸附劑應在具有類似預期用途的其它設備中處置，GlobeCore 技術可確保通過燃燒回收吸附劑，並重複使用其再生柴油燃料（至少 300 次再活化）。

操作週期的持續時間和耗電量

1. 油再生（持續時間-6 h，消耗功率-1.5 kW/h）。
2. 吸附劑的重新活化：

• 準備工作（持續時間-1 h，消耗功率-6.25 kW/h）。
• 吸附劑點燃（持續時間-1 h，消耗功率-17.5 kW/h）。
• 吸附劑燃燒（持續時間-15 h，消耗功率-25.5 kW/h）。
• 填充（持續時間-0.5 h，消耗功率-6.5 kW/h）。

優勢

• 操作方便。該裝置通過雙扣式快速接頭快速連接到清潔和骯髒的油槽；油的淨化過程通過玻璃視窗進行可看見的監控；在再生圓柱的底部有一個服務艙口，用於維護和清洗。
• 該裝置可以在自動模式下運轉。選擇所需的操作模式，通過顯示單元助記符號的觸控螢幕來控制轉動裝置。為了啟用控制按鈕，操作員只需觸摸它們。
• 吸附劑無需從裝置中取出即可回收，冷卻後可立即用於下一個再生循環。在最後一次的活化結束時，吸附劑可以作為建築骨料或在農業中用來鬆動緊實的土壤。
• 在設備運轉過程中，不會出現向環境中排放有害氣體的情況。該裝置配備了一個用於中和燃燒產物的雙級系統，該系統由一個碳過濾器和一個催化轉化器組成。

Diesel fuel is used in many industries. Its consumers include ships, tractors, harvesters, trucks, diesel trains, etc. Many enterprises try to purchase large batches of diesel fuel in order to insure themselves against seasonal price fluctuations and to avoid overpaying through the use of warehouse inventory of the petroleum product.

During long-term storage, not all types of diesel fuels feature the required stability. Diesel fuel undergoes oxidation, water ingress, and formation of resinous substances. As a result, the fuel turns dark and loses its operational properties. Such fuel cannot be used, because it will impair the engine operation due to resinous deposits in the engine fuel supply devices, as well as soot caking on the walls of combustion chambers, exhaust valves, and nozzles, and water will render the high pressure fuel pump inoperative. Therefore, such fuel should be prepared before feeding into diesel engines and power plants.

Diesel fuel polishing

Various methods are used to purify diesel fuel after long-term storage: settling, filtration, centrifugation. These methods are suitable for removing the mechanical impurities and water; however, they are unable to restore the original color and smell of the fuel, as well as to reduce the sulfur content. This requires using additional purification by means of special adsorbents of natural origin.

CMM-6RL unit for dark diesel fuel polishing

The technology for adsorptive dark diesel fuel polishing is implemented in CMM-6RL unit. The unit consists of six columns each of which is filled with an adsorbent having good absorptive properties. When passing through the columns, the adsorbent captures unsaturated and aromatic hydrocarbons, asphalt-resin substances, sulfur-, nitrogen- and acid-containing compounds from the fuel. Diesel fuel is clarified, regains its group composition and operational properties.

After saturation of the adsorbent, СMM-6RL unit switches to the reactivation mode. In this mode, the adsorbent properties are reclaimed after which the adsorbent is reused for diesel fuel polishing.

Operation features of CMM-6RL unit for diesel fuel polishing

The main feature of CMM-6RL unit is the possibility to reactivate the adsorbent without removing it from the regeneration columns. If the used adsorbent should be disposed of in other equipment of a similar intended purpose, GlobeCore technology ensures reclamation of the adsorbent by burning, as well as repeated use thereof for diesel fuel polishing (at least 300 reactivations).

Duration of operating cycles and power consumption

CMM-6RL unit for diesel fuels polishing sequentially operates in the following modes:

1. Fuel polishing (duration — 6 h, power consumption — 1.5 kW/h);
2. Adsorbent reactivation:

• preparation (duration — 1 h, power consumption — 6.25 kW/h);
• adsorbent ignition (duration — 1 h, power consumption — 17.5 kW/h);
• adsorbent combustion (duration — 15 h, power consumption — 25.5 kW/h);
• refilling (duration — 0.5 h, power consumption — 6.5 kW/h).

Advantages

• Convenience of operation. The unit is quickly connected to tanks for clean and dirty oil through camlock quick couplings; the oil purification process is visually monitored by means of sight glasses; a service hatch is provided at the bottom of the columns for their maintenance and cleaning.
• The unit can operate in automatic mode. The required operating mode is selected, and the actuators are controlled from the touch panel which displays a mnemonic diagram of the unit. In order to enable the control buttons, the operator just needs to touch them.
• The adsorbent is reclaimed without being removed from the unit and can be used for the next regeneration cycle immediately after cooling. At the end of the last reactivation, the adsorbent can be used as a construction aggregate or in agriculture to loosen compact soils.
• There occur no harmful emissions into the environment during the unit operation. The unit is equipped with a two-stage system for neutralization of combustion products which consists of a carbon filter and a catalytic converter.
