Columns for absorbing or stripping gases
Aeration Columns. Branch designs and builds custom fabricated mass transfer equipment for gas absorption and removal. The most common types of aeration devices we provide are: •Packed Columns for either absorbing or stripping gases. •Tray Column. In water service applications, air will saturate incoming water as it moves vertically downward through the columns. Volatile gases trapped in the water are released into the air as the water contacts the high surface packing media. Units can... (read more)
