At the same time, in some cases, stripping is also used to remove light components in the liquid. For example, in the oil refining industry, steam is often used as a stripping agent to remove light components in oil products. Therefore, stripping can be used in combination with absorption or alone. The sewage stripping tower is mainly used to remove solutes such as sulfides in sewage. Some low-temperature media will be generated during the operation of the sewage stripping tower.
