This invention discloses a low-concentration hydrophobic organic gas separation and recovery tower and a separation and recovery method. The separation and recovery tower utilizes the immiscibility of hydrophobic organic liquids and water, as well as their different densities. Organic liquids with a density less than water float to the surface and are discharged into a separation tank via an overflow port, then discharged and recovered through the bottom outlet of the separation tank.

This not only maintains the condensation effect but also improves the solubility of the gas in the water, allowing the water inside the tower to be recycled for a long time. This achieves highly efficient separation and recovery of organic gases, with a recovery rate of over 90%.
