H2S gas often appears in oil and gas field development. To understand its presence in the water treatment process， the H2S variation trends in produced water after treated by flotation process are discussed. The H2S content variation in vapor and water phases of compact flotation unit （CFU） is simulated by HYSYS， considering different factors such as pressure， temperature and floatation gas quantity. It leads to a certain understanding about the existence of the H2S gas in water treatment systems.
