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.
Humidity is the amount of moisture in the air (in grams per cubic meter for example), but relative humidity is a percentage that shows a comparison between the amount of vapor present and the amount the air can hold (at the maximum) at a given temperature.BSOLUTE HUMIDITY: Absolute humidity (expressed as grams of water vapor per cubic meter volume of air) is a measure of the actual amount of water vapor (moisture) in the air, regardless of the air's temperature.
