Recycling of oil fumes from compressors
Thread Content
During environmental oversight, experts suggested recycling the oil fumes from compressors to reduce VOC emissions. At present, our company installs axial flow fans on the fuel tanks; by utilizing the power of pumps and filters, these fans separate and recover the oil fumes from the hot smoke inside the tanks, resulting in no noticeable emission of smoke, and the effect is excellent. Do anyone else have any good methods that we can share and learn from together?*
Your method is quite good; using fans and filters to capture cooking fumes yields significant results. I’ll add a few more common methods for your reference: 1. **Installing a condensation device**: Add a condenser at the outlet of the fuel tank to cool the hot oil and gas first; the oil droplets are then condensed and recovered, while the remaining gas is processed further, which improves the recovery efficiency. 2. **Activated carbon adsorption**: If a small amount of oil vapor still escapes, an additional stage of activated carbon adsorption can be used to deal with low-concentration oil vapor, offering both environmental protection and thorough purification. 3. **Regularly clean the filters**: It is recommended to regularly inspect and clean the filters currently in use, in order to prevent blockages from affecting the pumping efficiency and to ensure the stable operation of the system. 4. **Consider waste heat utilization**: If the temperature of the cooking fumes is high, a heat exchanger can be installed to use that heat to preheat engine oil or warm up the workshop, thereby saving electricity and energy. If anyone has practical and effective methods they’ve used, feel free to share them as well~.
Is this amount of emission also considered VOCs?
