What technologies are people using for VOC treatment in atmospheric pressure tank farms? Welcome to share your insights and guidance...
The main approach depends on the substance stored in the tank; for substances with high boiling points, recovery combined with activated carbon is used, while for those with low boiling points, activated carbon alone is sufficient
This is mainly determined by the recovery properties of the material in the storage tank and the **allowed atmospheric emission concentration； Generally, for applications with low processing volumes or modest requirements regarding emission control, activated carbon can be used ； For those with a foul odor or **low concentrations required for atmospheric emission control, RTO or catalytic combustion is generally used for treatment.
Furthermore, within this buffer tank, the flow rate will gradually decrease (if there is no condensation or absorption, it can be assumed that the residence time equals the residence time of the gas in the remaining volume of the tank minus the residence time of that same amount of gas in the pipeline based on the flow rate)
The preferred solution for controlling VOCs in storage tanks is the internal floating disk, as it covers 95% of the surface area where vaporization occurs. Our company recommends improving the design of these internal floating disks as well as the sealing techniques, so that existing storage tanks can achieve controlled emissions; through such technical upgrades, organized emission can be ensured. It basically meets the national standard emission values. I specialize in such renovation projects; feel free to contact me if you have any questions. 15122269996
Our company will develop corrective measures based on the specific conditions of the storage tank on site. Through technical upgrades, activated carbon and oil vapor recovery, as well as combustion methods, all **help to reduce operating costs.
