Natural-gas processing plants purify raw natural gas by removing common contaminants such as water, carbon dioxide (CO2) and hydrogen sulfide (H2S). Some of the substances which contaminate natural gas have economic value and are further processed or sold.
Besides, what is cryogenic processing natural gas?
Cryogenic separation is a processing operation that is commonly used to extract natural gas liquids (NGLs) from raw natural gas. At this temperature, methane (an extremely light hydrocarbon) stays in the stream, while the other heavier hydrocarbons condense into liquid form and flow out.
Likewise, is natural gas liquid or gas?
Overview of Natural Gas, Natural Gas Liquids, Liquefied Natural Gas, and Gas-To-Liquids. Natural Gas – Natural gas is a hydrocarbon gas. It consists primarily of methane but may also include other alkanes, carbon dioxide, nitrogen, and hydrogen sulfide. Natural gas is flammable and can be used for energy.
Why is natural gas dangerous to life?
It is dangerous because natural gas is flammable, which means that if there's a flame or even a spark in the area of a leak, it could cause a fire or explosion. Natural gas can also leak if a natural gas appliance, like a stove, water heater or furnace, isn't hooked up correctly.
Is natural gas from crude oil?
Natural gas also occurs with deposits of crude oil, and this natural gas is called associated natural gas. Natural gas deposits are found on land, and some are offshore and deep under the ocean floor. A type of natural gas found in coal deposits is called coalbed methane.
