What is the composition of condensate?
Gas condensate is a hydrocarbon liquid stream separated from natural gas and consists of higher-molecular-weight hydrocarbons that exist in the reservoir as constituents of natural gas but which are recovered as liquids in separators, field facilities, or gas-processing plants.
What is the composition of exhaust gas?
Composition. The largest part of most combustion gas is nitrogen (N2), water vapor (H2O) (except with pure-carbon fuels), and carbon dioxide (CO2) (except for fuels without carbon); these are not toxic or noxious (although water vapor and carbon dioxide are greenhouse gases that contribute to climate change).
What is condensate gas ratio?
Condensate to Gas Ratio (CGR) is a measure of liquid content of a naturally occurring hydrocarbon mixture that is classified as gas condensate at reservoir conditions. It is also one of the most important parameters that impacts the economics of gas projects.
What causes gas to condensate?
Gas condensate condenses out of the raw natural gas if the temperature is reduced to below the hydrocarbon dew point temperature of the raw gas. The composition of the gas condensate liquids is dependent upon the type of natural gas and the composition of the natural gas.
What is natural gas condensate made of?
A natural gas liquid with a low vapor pressure compared with natural gasoline and liquefied petroleum gas. Condensate is mainly composed of propane, butane, pentane and heavier hydrocarbon fractions.
What are the five exhaust gases?
The five gasses measured (for petrol emissions) by the latest technology exhaust analysers are: HC, CO, CO2, O2 and NOx.
What pollutants are in car exhaust?
The following are the major pollutants from motor vehicles:
- Particulate matter (PM). One type of particulate matter is the soot seen in vehicle exhaust.
- Volatile Organic Compounds (VOCs).
- Nitrogen oxides (NOx).
- Carbon monoxide (CO).
- Sulfur dioxide (SO2).
- Greenhouse gases.
How is condensate produced?
Condensates form when their vapor pressure is lowered to the point that the natural gas liquids condense out of the gas stream into a liquid that can be stored at room temperature.
What is the difference between gas and condensate?
A typical ‘natural gas liquids’ breakdown would be about 83% gaseous liquids, and 17% natural gasoline (it varies, and can be as much as 22%). Condensate refers to a specific portion of the ‘Natural Gas Liquids’. It is more usually referred to as ‘lease condensate’.
What is exhaust gas condensation?
The Thermodynamics of Exhaust Gas Condensation 2017-01-9281 Water vapor is, aside from carbon dioxide, the major fossil fuel combustion by-product. Depending on its concentration in the exhaust gas mixture as well as on the exhaust gas pressure, its condensation temperature can be derived.
What is gas condensate made of?
Gas condensate (sometimes referred to as condensate) is a mixture of low-boiling hydrocarbon liquids obtained by condensation of the vapors of these hydrocarbon constituents either in the well or as the gas stream emits from the well.
Does exhaust gas contain pollutants?
The exhaust gas mixture does however contain some pollutants coming from the fuel, engine oil, and charge air, which can react with the water vapor and affect the condensation process. For instance, sulfur trioxide present in the exhaust, reacts with water vapor forming sulfuric acid.
What is the composition of exhaust gases?
The exhaust gases from internal combustion engines. are complex mixtures consisting principally of the products. of complete combustion, small amounts of the oxidation. products of sulfur and nitrogen, and compounds derived. from the fuel and lubricant.
