What causes gas to condense?
Condensation commonly occurs when a vapor is cooled and/or compressed to its saturation limit when the molecular density in the gas phase reaches its maximal threshold. Vapor cooling and compressing equipment that collects condensed liquids is called a “condenser”.
How do you condense natural gas?
Separating the condensate from the raw natural gas The raw natural gas feedstock from a gas well or a group of wells is cooled to lower the gas temperature to below its hydrocarbon dew point at the feedstock pressure. This condenses a large part of the gas condensate hydrocarbons.
How do you remove condensate from natural gas?
Pass natural gas into a heat exchanger to lower the temperature of the gas. Move the heated gas into a low temperature separator. As the gas rapidly cools, water vapor will form into solid ice crystals and drop out of the natural gas.
What does condensate mean in oil and gas?
Condensate is a mixture of light liquid hydrocarbons, similar to a very light (high API) crude oil. It is typically separated out of a natural gas stream at the point of production (field separation) when the temperature and pressure of the gas is dropped to atmospheric conditions.
At what temperature does gas condense?
For temperature above 0 Kelvin and 273.15 Kelvin (0 Celsius) or below then water condensing from the atmosphere would form ice. For temperature between 0 Celsius and 100 Celsius liquid water would condense. Above 100 Celsius water wouldn’t condense unless the gas phase of the system was under pressure.
What is the gravity of condensate?
Condensate specific gravity ranges between 0.74 and 0.82 (60 to 40 °API), although values as high as 0.88 (as low as 29 °API) have been reported [21]. Material balance equations developed for dry gases can be used for a gas condensate reservoir as long as its pressure remains above the dew point.
What Colour is condensate?
The condensate colour can be water-white or dark. Dark condensates usually have relatively high specific gravity and are associated with high dew point gases.
