What happens gas condensate?

Some gas species within the raw natural gas will condense to a liquid state if the temperature is reduced to below the hydrocarbon dew-point temperature at a definitive pressure. A gas-condensate reservoir (also called a dew point reservoir) is a reservoir in which condensation causes a liquid to leave the gas phase.

Is natural gas a condensate hazardous waste?

Hazard Identification More serious health effects can occur if condensate is inhaled or swallowed. Natural gas condensate (sweet) may contain variable amounts of benzene and n-hexane. Long-term exposure to these materials has been shown to lead to systemic toxicity such as leukemia and peripheral neurotoxicity.

Does condensate have h2s?

Hydrogen sulfide (H2S), a corrosive and toxic gas, when present in produced fluids such as condensate, gas and water, poses serious health and operational hazards.

What is a condensate cargo?

Also known as: Lease condensate. 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.

What is the purpose of natural gas condensate?

Because condensate is typically liquid in ambient conditions and also has very low viscosity, condensate is often used to dilute highly viscous heavier oils that cannot otherwise be efficiently transported via pipelines. In particular, condensate is frequently mixed with bitumen from oil sands to create dilbit.

What is condensate worth?

How Much is a Barrel of Condensate Worth? Just as crude oil prices vary depending on region, quality, and gravity, condensate prices depend on where it is produced, gravity or BTU, and market demand. As of June 2021, a barrel of East Texas Condensate cost nearly $66.

Is condensate toxic?

Furnace condensate is not a toxic liquid; however, it is an acidic solution that consists of water, carbon dioxide, nitric acid, and, in some cases, traces of metal, mold, and mildew. This condensate is corrosive and has to be neutralized before getting drained into the wastewater system.

What is the density of condensate?

0.71-0.76 g/cm3
Physical properties of the API gravity and density of condensate are presented in the range of 55-60° and 0.71-0.76 g/cm3.

How is condensate formed?

Condensate is the liquid formed when steam passes from the vapor to the liquid state. In a heating process, condensate is the result of steam transferring a portion of its heat energy, known as latent heat, to the product, line, or equipment being heated.

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 natural gas liquids and condensate?

The key difference between condensate and natural gas liquids is that condensate is the end product of a condensation reaction, whereas natural gas liquid is the low-density mixture of hydrocarbon liquids that occurs as gaseous compounds in the raw natural gas that forms from many natural gas fields.

Where does condensate come from?

They occur as vapor in natural gas and can be dissolved in crude oil or occur separately in oil reservoirs. 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 Khuff Formation in the Middle East?

For many years, Middle East explorationists have been fascinated by the Khuff Formation – as well they might. Several supergiant gas fields (defined as those with reserves of over 10 Tcf) have been found reservoired in this Permo-Triassic horizon in countries of the Persian Gulf, including Saudi Arabia, Bahrain, Qatar and Iran.

How does diagenesis reduce poroperm in the Khuff reservoir?

Sometimes, as in the Ghawar Field in Saudi Arabia, diagenesis reduces poroperm in the Khuff reservoir by filling the pores with anhydrite. Petrographic study of the Khuff reservoir indicates that the rock has undergone many diagenetic changes.

Where are the khuff gas fields?

Large onshore gas fields, such as Kangan, Dalan and Asaluyeh, have also been discovered in Khuff-equivalent strata in southern Iran. The Khuff formation is developed over several Middle East countries.

What is the Permo-Triassic Khuff Formation?

The Permo-Triassic Khuff Formation can be seen cropping out at the surface in Wadi Shah, on the northern Oman-Emirates border. The thinning- and shaling-up intertidal cycles can be seen clearly in the K3 section, which is abruptly overlain by subtidal sediments of the K2 Khuff horizons. Darker horizons often show evidence of oil staining.
