Produced water is chemically very complex. The process of producing and processing produced water causes changes in temperature and pressure. The addition of treating chemicals, along with the presence of coproduced gas, oil, and likely solids, changes the produced-water properties and behavior.
Many times, relative humidity can be misleading. For example, a temperature of 30 and a dew point of 30 will give you a relative humidity of 100%, but a temperature of 80 and a dew point of 60 produces a relative humidity of 50%. It would feel much more humid on the 80 degree day with 50% relative humidity than on the 30 degree day with a 100% relative humidity.
Relative humidity decreases as temperature increases. The importance of air temperature to moisture is obvious. At 80Â°, the air has a relatively low humidity and is relatively dry. As it cools, the humidity increases, reaching its saturation point at 40Â°. Now the air is very moist, and clouds will form.
